Section 1 SWPPP Requirements

1.1 INTRODUCTION This SWPPP has been prepared for the Calimesa - Avenue L Storm Drain, Stage 2 project, located in the city of Calimesa, Riverside County, California, and generally consists of the installation of reinforced concrete pipe storm drain beneath existing paved streets. The project begins approximately 200 feet east of the Avenue L and 4th Street intersection, and traverses approximately 7,100 feet northeasterly ending on Douglas Street. The project's location is shown on the Site Maps in Appendix B.

The terms "discharger", "legally responsible party", "legally responsible person", and "LRP" are used interchangeably in this document and universally refer to the Riverside County Flood Control and Water Conservation District. This Stormwater Pollution Prevention Plan (SWPPP) is designed to comply with California's General Permit for Stormwater Discharges Associated with Construction and Land Disturbance Activities (General Permit or CGP) Order No. 2009-0009-DWQ as amended by Order No. 2010-0014-DWQ (NPDES No. CAS000002) issued by the State Water Resources Control Board (State Water Board).

This SWPPP has been prepared following the SWPPP Template provided on the California Stormwater Quality Association Stormwater Best Management Practice Handbook Portal: Construction (CASQA, 2010). In accordance with the General Permit, Section XIV, this SWPPP is designed to address the following:

• Pollutants and their sources, including sources of sediment associated with construction, construction site erosion and other activities associated with LUP activity are controlled;

• Where not otherwise required to be under a Regional Water Quality Control Board (Regional Water Board) permit, all non-stormwater discharges are identified and eliminated, controlled, or treated; and

• Site BMPs are effective and result in the reduction or elimination of pollutants in stormwater discharges and authorized non-stormwater discharges from construction activity to the Best Available Technology/Best Control Technology (BAT/BCT) standard.

The Calimesa - Avenue L Storm Drain, Stage 2 project is a Linear Underground/Overhead Project (LUP) and, therefore, must comply with provisions set forth in Attachment A of the CGP.

This SWPPP must be evaluated and revised on an ongoing basis by a QSP in order to document the changes and progression of construction activity throughout the life of the project.


1.2 PERMIT REGISTRATION DOCUMENTS Required Permit Registration Documents (PRDs) shall be submitted to the State Water Board via the Stormwater Multi Application and Report Tracking System (SMARTS) by the Legally Responsible Person (LRP), or authorized personnel (i.e., Approved Signatory) under the direction of the LRP.

The project-specific PRDs include (per CGP Attachment A, Section B):

1. Notice of Intent (NOI)

Prior to construction activities, the LRP of a proposed linear underground/overhead project shall utilize the processes and methods provided in Attachment A.2, Permit Registration Documents (PRDs) – General Instructions for Linear Underground/Overhead Projects to comply with the Construction General Permit.

2. Risk Assessment (Construction Site Sediment and Receiving Water Risk Determination)

3. Site Map

LRPs submitting PRDs shall include at least 3 maps. The first map will be a zoomed 1000-1500 ft vicinity map that shows the starting point of the project. The second will be a zoomed map of 1000-1500 ft showing the ending location of the project. The third will be a larger view vicinity map, 1000 ft to 2000 ft, displaying the entire project location depending on the project size, and indicating the LUP type (1, 2 or 3) areas within the total project footprint.

4. Drawings

LRPs submitting PRDs shall include a construction drawing(s) or other appropriate drawing(s) or map(s) that shows the locations of storm drain inlets and waterbodies that may receive discharges from the construction activities and that shows the locations of BMPs to be installed for all those BMPs that can be illustrated on the revisable drawing(s) or map(s). If storm drain inlets, waterbodies, and/or BMPs cannot be adequately shown on the drawing(s) or map(s) they should be described in detail within the SWPPP.

5. Signed Certification Statement (LRP Certification is provided electronically with SMARTS PRD submittal);

6. SWPPP

LUP dischargers shall comply with the SWPPP Preparation, Implementation, and Oversight requirements in Section K of CGP Attachment A.

7. Contact information

LUP dischargers shall include contact information for all contractors (or subcontractors) responsible for each area of an LUP project. This should include the names, telephone numbers, and addresses of contact personnel. Specific areas of responsibility of each contact, and emergency contact numbers should also be included.

A copy of the submitted PRDs shall also be kept in Appendix C along with the CGP App ID confirmation.


1.3 SWPPP AVAILABILITY AND IMPLEMENTATION The discharger shall make the SWPPP available at the construction site during working hours (see Section 7.5 of CSMP for working hours) while construction is occurring and shall be made available upon request by a State or Municipal inspector. When the original SWPPP is retained by a crewmember in a construction vehicle and is not currently at the construction site, current copies of the BMPs and map/drawing will be left with the field crew and the original SWPPP shall be made available via a request by radio/telephone. (CGP Section XIV.C)

The SWPPP shall be implemented concurrently with the start of ground disturbing activities.

1.4 SWPPP AMENDMENTS The SWPPP should be revised when:

• If there is a General Permit violation;

• When there is a reduction or increase in total disturbed acreage (General Permit Section II Part C); or

• BMPs do not meet the objectives of reducing or eliminating pollutants in stormwater discharges.

Additionally, the SWPPP shall be amended when:

• There is a change in construction or operations which may affect the discharge of pollutants to surface waters, groundwater(s), or a municipal separate storm sewer system (MS4);

• When there is a change in the project duration that changes the project's risk level; or

• When deemed necessary by the QSD. The QSD has determined that the changes listed in Table 1.1 can be field determined by the QSP. All other changes shall be made by the QSD as formal amendments to the SWPPP.

The following items shall be included in each amendment:

• Who requested the amendment;

• The location of proposed change;

• The reason for change;

• The original BMP proposed, if any; and

• The new BMP proposed.

The amendment shall be logged at the front of the SWPPP and certification kept in Appendix D. The SWPPP text shall be revised, replaced, and/or hand annotated as necessary to properly convey the amendment. SWPPP amendments must be made by a QSD. The following changes have been designated by the QSD as "to be field determined" and constitute minor changes that the QSP may implement based on field conditions.

Section 2 Project Information

2.1 PROJECT AND SITE DESCRIPTION This Stormwater Pollution Prevention Plan (SWPPP) has been created for the Calimesa - Avenue L Storm Drain, Stage 2 project. Refer to the vicinity map located in Appendix B for the site location.

2.1.1 Site Description The project is located entirely in the city of Calimesa, Riverside County. The project is located in Section 13 of Township 2 South, Range 1 West and Section 18 of Township 2 South, Range 2 West of the U.S. Geological Survey 7.5-minute topographic quadrangle maps for El Casco and Yucaipa (33.9994 North / 117.0444 West).

The project is a linear underground/overhead project (LUP) and begins approximately 200 feet east of the Avenue "L" and 4th Street intersection, and traverses approximately 7,100 feet northeasterly, ending on Douglas Street. Construction of short laterals (less than 100') and catch basins will also occur on the North-South streets intersecting Avenue L namely, Second Street, California Street and Bryant Street. An approximately 150' lateral will be installed North from Avenue L on Third Street. Project exhibits are located in Appendix B of this SWPPP.

Based on the proposed construction activity and the criteria in Attachment A.2 of the CGP ("Calculating Land Disturbance Areas of LUPs"), the initial estimated disturbance area for the Calimesa - Avenue L Storm Drain, Stage 2 project is 6.9 acres (4.6 acres of pavement overlay, 1.3 acres of full depth in-trench pavement replacement, and a 1 acre storage or staging area). Any changes to the initial estimate must be reported electronically (via SMARTS) and recorded in Appendix E of this SWPPP.

2.1.2 Existing Conditions Approximately 100% of the pre-project disturbance area is impervious and post-project imperviousness will not increase.

2.1.3 Existing Drainage Existing drainage in the project area is entirely overland. The tributary area for the project is comprised substantially of residential parcels draining to the public streets, with only two known commercial parcels (also draining to the public streets). The local drainage pattern flows from North to South and East to West and is largely contained in street right of way for the 10 year 24-hour event. Near the beginning of this LUP project there exists several catch basins which tie into the Calimesa - Avenue L Storm Drain, Stage 1 (District Drawing No. 5-197), which runs West in Avenue L to Calimesa Boulevard, where it travels North and West, ending in a sump located near Interstate 10.

2.1.4 Geology and Groundwater Per the project geotechnical report, the majority of the proposed storm drain alignment is underlain by a two-layer sequence of detrital alluvial materials: the upper layer consisting of loose to medium dense very silty sand and stiff to hard non-plastic sandy silt; the lower layer


consisting of massive to indistinctly stratified medium dense to dense silty sand, clayey sand, gravelly sand, and uncommon sandy gravel. No groundwater was encountered in any of the exploratory borings, and is speculated by the project geotechnical report to be very deep. Nearby groundwater monitoring wells have found the average static groundwater surface elevation to vary from 150 to 170 feet below ground surface.

2.1.5 Project Description The project entails the construction of below-ground storm drain facilities as well as related above- and below-ground drainage structures, such as access manholes and catch basins. Street paving, both full depth structural replacement in-trench and pavement overlay outside of trench, will also occur.

The project includes the following type of facilities:

• Storm drain, constructed below ground

• Surface and below ground drainage structures

• Street paving

2.1.6 Developed Condition

2.2 PERMITS AND GOVERNING DOCUMENTS In addition to the General Permit, the following documents have been taken into account while preparing this SWPPP

• Regional Water Board requirements

• Basin Plan requirements

• Contract Documents

• Air Quality Regulations and Permits

• Federal Endangered Species Act

• National Historic Preservation Act/Requirements of the State Historic Preservation Office


• State of California Endangered Species Act

• Clean Water Act Section 401 Water Quality Certifications and 404 Permits

• CA Department of Fish and Game 1600 Streambed Alteration Agreement

2.3 STORMWATER RUN-ON FROM OFFSITE AREAS Runoff and run-on controls are not required for Type 1 LUP.


2.4 FINDINGS OF THE CONSTRUCTION SITE SEDIMENT AND RECEIVING WATER RISK DETERMINATION

A construction site risk assessment has been performed for the project. The result is that this project is classified as a Type 1 LUP, which has the following requirements:

• Less than 30% of soil disturbances occur on unpaved surfaces (including staging areas).

• At the end of the work day, the construction site must be returned to pre-development or equivalent condition. For this project, all disturbed soil piles from trench excavation must be covered and secured with sandbags or other means around the perimeter. Any pipe lain within an open trench will be plugged at the downstream end to eliminate runoff leaving the site via the already installed storm drain line.

The risk level was determined by a site specific analysis. The risk level is based on project duration, location, proximity to impaired receiving waters and soil conditions. A copy of the Risk Level determination submitted on SMARTS with the PRDs is included in Appendix C.

Table 2.2 and Table 2.3 summarize the sediment and receiving water risk factors and document the sources of information used to derive the factors.

2.5 CONSTRUCTION SCHEDULE

The site sediment risk was determined based on construction taking place between April 18, 2012 and November 14, 2012. Modification or extension of the schedule (start and end dates) may affect risk determination and permit requirements. The LRP shall contact the QSD if the schedule changes during construction to address potential impact to the SWPPP. The estimated schedule for planned work can be found in Appendix F.

2.6 POTENTIAL CONSTRUCTION ACTIVITY AND POLLUTANT SOURCES Appendix G includes a list of construction activities and associated materials that are anticipated to be used onsite. These activities and associated materials will or could potentially contribute pollutants, other than sediment, to stormwater runoff.

The anticipated activities and associated pollutants were used in Section 3 to select the Best Management Practices for the project. Location of anticipated pollutants and associated BMPs are show on the Site Map in Appendix B.

2.7 IDENTIFICATION OF NON-STORMWATER DISCHARGES Non-stormwater discharges consist of discharges which do not originate from precipitation events. The General Permit provides allowances for specified non-stormwater discharges that do not cause erosion or carry other pollutants.

Non-stormwater discharges into storm drainage systems or waterways, which are not authorized under the General Permit and listed in the SWPPP, or authorized under a separate NPDES permit, are prohibited.

Non-stormwater discharges that are authorized from this project site include the following:

• None

These authorized non-stormwater discharges will be managed with the stormwater and non-stormwater BMPs described in Section 3 of this SWPPP and will be minimized by the QSP.

Activities at this site that may result in unauthorized non-stormwater discharges include:

•

Steps will be taken, including the implementation of appropriate BMPs, to ensure that unauthorized discharges are eliminated, controlled, disposed, or treated onsite.

Discharges of construction materials and wastes, such as fuel or paint, resulting from dumping, spills, or direct contact with rainwater or stormwater runoff, are also prohibited.

The following additional information is provided regarding non-stormwater discharges:

Dewatering (Discharge of Ponded/Retained Stormwater to Surface Waters

It is the responsibility of the Contractor to contact the appropriate California Regional Water Quality Control Board (Regional Board) to see if a permit is required for this activity. If there is a situation where there is ponded water due to rainfall collecting in a temporary sump condition caused by construction, the water may need to be removed. If approved by the Site LRP, the water may be pumped out of the sump and discharged at the site as long as the water is not pumped directly into the storm drain. The water must


be pumped into an open area, with vegetation, with prior permission of the property owner, so that it can naturally percolate into the ground and not discharge into the storm drain system. In all other cases the water must be pumped to a truck and shipped offsite for proper disposal.

2.8 REQUIRED SITE MAP INFORMATION The Site Maps and Drawings are included in Appendix B of this SWPPP.

Site Maps

In accordance with the CGP, three site maps must be included with the PRDs. The first will be a 1000-1500 ft vicinity map that shows the starting point of the project. The second will be a zoomed map of 1000-1500 ft showing the ending location of the project. The third will be a larger view vicinity map, 1000 ft to 2000 ft, displaying the entire project location depending on the project size, and indicating the LUP type (1, 2 or 3) areas within the total project footprint.

Drawings

Construction drawing(s) or other appropriate drawing(s) or map(s) that show: the locations of the storm drain inlets and waterbodies that may receive discharges from the construction activities; and the locations of BMPs to be installed for all those BMPs that can be illustrated on revisable drawing(s) or map(s).

As conditions change it may be necessary to amend the site maps. Table 2.4 identifies sheet numbers where required elements are illustrated.

3.2 EROSION AND SEDIMENT CONTROL Erosion and sediment controls are required by the General Permit to provide effective reduction or elimination of sediment related pollutants in stormwater discharges and authorized non-stormwater discharges from the Site. Applicable BMPs are identified in this section for erosion control, sediment control, tracking control, and wind erosion control.

3.2.1 Erosion Control Erosion control, also referred to as soil stabilization, consists of source control measures that are designed to prevent soil particles from detaching and becoming transported in stormwater runoff. Erosion control BMPs protect the soil surface by covering and/or binding soil particles.


This construction project will implement the following practices to provide effective temporary and final erosion control during construction:

1. Preserve existing vegetation where required and when feasible.

2. The area of soil disturbing operations shall be controlled such that the Contractor is able to implement erosion control BMPs quickly and effectively.

3. Stabilize non-active areas within 14 days of cessation of construction activities or sooner if stipulated by local requirements.

4. Control erosion in concentrated flow paths by applying erosion control blankets, check dams, erosion control seeding or alternate methods.

5. Prior to the completion of construction, apply permanent erosion control to remaining disturbed soil areas.

Sufficient erosion control materials shall be maintained onsite to allow implementation in conformance with this SWPPP.

The following temporary erosion control BMP selection table indicates the BMPs that shall be implemented to control erosion on the construction site. Fact Sheets for temporary erosion control BMPs are provided in Appendix H.

These temporary erosion control BMPs shall be implemented in conformance with the following guidelines and as outlined in the BMP Factsheets provided in Appendix H. If there is a conflict between documents, the Site Map will prevail over narrative in the body of the SWPPP or guidance in the BMP Fact Sheets. Site specific details in the Site Map prevail over standard details included in the Site Map. The narrative in the body of the SWPPP prevails over guidance in the BMP Fact Sheets.

Scheduling EC-1 Scheduling - The project schedule will show how BMP implementation relates to soil disturbing and re-stabilization practices. Non-active areas will be stabilized within 14 days of the cessation of any soil disturbing activities or one day prior to the onset of precipitation, whichever occurs first. The weather forecast will be monitored for rainfall. When rainfall is predicted, the schedule shall be adjusted to allow for the implementation of soil stabilization and sediment controls on any disturbed areas prior to the onset of rain.

Wind Erosion Control WE – 1 Wind Erosion Control – Water will be applied to disturbed areas and stockpiles as necessary to prevent or alleviate erosion by the forces of wind.

3.2.2 Sediment Controls Sediment controls are temporary or permanent structural measures that are intended to complement the selected erosion control measures and reduce sediment discharges from active construction areas. Sediment controls are designed to intercept and settle out soil particles that have been detached and transported by the force of water.

The following sediment control BMP selection table indicates the BMPs that shall be implemented to control sediment on the construction site. Fact Sheets for temporary sediment control BMPs are provided in Appendix H.

Non-stormwater BMPs shall be implemented in conformance with the following guidelines and in accordance with the BMP Fact Sheets provided in Appendix H. If there is a conflict between documents, the Site Map will prevail over narrative in the body of the SWPPP or guidance in the BMP Fact Sheets. Site specific details in the Site Map prevail over standard details included in the Site Map. The narrative in the body of the SWPPP prevails over guidance in the BMP Fact Sheets.

Water Conservation Practices NS-1 Water Conservation Practices - Water equipment will be kept in good working condition. Leaks will be repaired immediately. Vehicles and equipment will not be washed on site. Water will not be used to clean construction areas.

Paving and Grinding Operation NS-3 Paving and Grinding Operations - Plastic material will be placed under paving equipment when not in use to catch drips or leaks. Paving equipment will be parked overnight at the staging area with plastic material placed underneath. Asphalt coated equipment will be cleaned off-site when possible. Residue from grinding or removal operations will be picked up by mechanical or manual means and disposed of properly. Inlets adjacent to paving operations will be protected. Following paving operations, the area will be swept and the inlets will be inspected for paving materials. If placing thermoplastic striping, the Contractor will fill the pre-heater carefully to avoid spillage and leave 6 inches of space at the top to allow for movement. Thermoplastic or bituminous material will not be transferred, pre-heated or loaded near drain inlets or water courses. Truck beds will be cleaned daily of loose debris and melted thermoplastic.

Illicit Connection- Illegal Discharge Connection NS-6 Illicit Connection/Illegal Discharge Detection and Reporting - The site will be inspected before the Project commences and regularly during the Project for illicit connections or illegal dumping or discharge. If any are found, they will be reported to the Engineering Project Manager and Project Manager at the time of discovery.

Vehicle and Equipment Cleaning NS-8 Vehicle and Equipment Cleaning - Vehicles and equipment will be cleaned off-site. Rinse water, wash waters or wash materials will not be disposed of on any impervious or pervious site surfaces, nor will they be disposed of into the storm drain system.

Vehicle and Equipment Fueling NS-9 Vehicle and Equipment Fueling - Onsite vehicle and equipment fueling should only be used where it is impractical to send vehicles and equipment offsite for fueling. A dedicated fueling area will be designated at the project site. The dedicated fueling area will be located on a level-grade area located at least 50 feet away from downstream drainage facilities and watercourses. The dedicated fueling area will be protected with berms and/or dikes to prevent run-on and run-off and to contain spills.

Absorbent spill clean-up materials and spill kits will be available at the dedicated fueling area. Tanks will not be "topped off". Oil, grease, and fuel will be prevented from leaking to the


ground, storm drains or surface waters. Fluid and oil leaks will be repaired immediately. Leaked material shall be disposed of properly.

Vehicle and Equipment Maintenance NS-10 Vehicle and Equipment Maintenance - Onsite vehicle and equipment maintenance should only be used where it is impractical to send vehicles and equipment offsite for maintenance. A dedicated maintenance area will be designated at the project site. The dedicated maintenance area will be located on a level-grade area located at least 50 feet away from downstream drainage facilities and watercourses. The dedicated maintenance area will be protected with berms and/or dikes to prevent run-on and run-off and to contain spills. Only minor maintenance, such as adding oil, fluids or lubricants will occur at the project site. Drip pans or plastic sheeting will be used when maintenance work is performed. Absorbent spill cleanup materials and spill kits will be available at the dedicated maintenance area. Oil, grease, and fuel will be prevented from leaking to the ground, storm drains or surface waters. Fluid and oil leaks will be repaired immediately. Leaked material shall be disposed of properly.

Concrete Curing NS-12 Concrete Curing - If curing compounds are used, overspray will be avoided. The drift of the curing compound will be minimized by applying the compound close to the concrete surface. An amount of compound that covers the surface but does not allow any run-off of the compound will be applied. Cure water will be directed away from inlets and watercourses to collection areas for proper removal.

Concrete Finishing NS-13 Concrete Finishing – Drift of dust and blast material will be minimized by keeping blasting nozzle close to the surface. Inlets will be protected during sandblasting operations, and water from blasting operations will be directed away from inlets and watercourses to collection areas for infiltration or other means of removal (dewatering).

3.3.2 Materials Management and Waste Management Materials management control practices consist of implementing procedural and structural BMPs for handling, storing and using construction materials to prevent the release of those materials into stormwater discharges. The amount and type of construction materials to be utilized at the site will depend upon the type of construction and the length of the construction period. The materials may be used continuously, such as fuel for vehicles and equipment, or the materials may be used for a discrete period, such as soil binders for temporary stabilization.

Waste management consists of implementing procedural and structural BMPs for handling, storing and ensuring proper disposal of wastes to prevent the release of those wastes into stormwater discharges.

Materials and waste management pollution control BMPs shall be implemented to minimize stormwater contact with construction materials, wastes and service areas; and to prevent materials and wastes from being discharged offsite. The primary mechanisms for stormwater contact that shall be addressed include:

• Direct contact with precipitation


• Contact with stormwater run-on and run-off

• Wind dispersion of loose materials

• Direct discharge to the storm drain system through spills or dumping

• Extended contact with some materials and wastes, such as asphalt cold mix and treated wood products, which can leach pollutants into stormwater

A list of construction activities is provided in Section 2.6. The following Materials and Waste Management BMP selection table indicates the BMPs that shall be implemented to handle materials and control construction site wastes associated with these construction activities. Fact Sheets for Materials and Waste Management BMPs are provided in Appendix H.

Material management BMPs shall be implemented in conformance with the following guidelines and in accordance with the BMP Fact Sheets provided in Appendix H. If there is a conflict between documents, the Site Map will prevail over narrative in the body of the SWPPP or guidance in the BMP Fact Sheets. Site specific details in the Site Map prevail over standard details included in the Site Map. The narrative in the body of the SWPPP prevails over guidance in the BMP Fact Sheets.

Material Delivery and Storage WM-l Material Delivery and Storage - A staging area will be designated at the project site by the Project Manager. The staging area will be used for storage, as needed. Construction materials will be delivered to the site and used quickly. Chemicals will be stored in watertight containers (with appropriate secondary containment to prevent any spillage or leakage) or in a completely enclosed storage shed. Spills and leaks will be contained and cleaned immediately. The exposure of construction materials to precipitation will be minimized. This does not include materials and equipment that are designed to be outdoors and exposed to environmental conditions (i.e. poles, equipment pads, cabinets, conductors, insulators, bricks, etc.). Backfill materials will be stockpiled per BMP WM-3 "Stockpile Management" when not in use.

Material Use

WM-2 Material Use – Hazardous materials use will be minimized onsite, and Material Safety Data Sheets (MSDS) will be available for all materials. Materials will be used only when and where needed to complete the construction activity. Use of erodible landscape materials will be discontinued two (2) days prior to a forecasted rain event, and materials will be covered/stored.

Stockpile Management WM-3 Stockpile Management - Any stockpiles will be located a minimum of 50 feet away from concentrated flows of stormwater, drainage courses, and inlets. All stockpiles will be bermed. Additionally, stockpiles will be covered at all times (to protect them from the wind and the rain) when they are not actively being used. Stockpiles that are unstabilized during construction activities will be sprayed with water as needed for dust control.

Spill Preservation and Control

WM-4 Spill Prevention and Control - The Contractor will assign and train appropriate spill response personnel. Oil, grease, and fuel will be prevented from leaking to the ground, storm drains or surface waters. All spills and leaks will be reported, contained and cleaned up immediately. All spill and leak wastes will be properly disposed of. The Project Manager and the Engineering Project Manager will be immediately notified of any spills and leaks. Spill and leak clean-up materials will be located near storage, unloading and use areas.

Solid Waste Management WM-5 Solid Waste Management- Solid wastes will be loaded directly into trucks and/or waste disposal containers for off-site disposal. Waste disposal containers will be covered at the end of every business day and during rain events. Discharges from waste disposal containers will be prevented from discharging to the stormwater drainage system or receiving water. Construction


debris and litter from the project will be removed weekly and by the end of the project. Collected litter and debris will not be placed by drain inlets or drainage systems.

Hazardous Waste Management WM-6 Hazardous Waste Management - If hazardous materials are encountered or used, such materials will be handled, treated, stored, and disposed of per the project's Special Provisions and all applicable laws and regulations. Hazardous spills will be reported, contained and cleaned up immediately.

Concrete Waste Management WM-8 Concrete Waste Management- All PCC waste shall be collected and properly disposed of. The waste shall be collected by sweeping, shoveling, and/or other mechanical means. The waste should not be allowed to enter the storm drains or watercourses. An above grade or mobile concrete washout will be constructed or placed at the staging area if concrete trucks or concrete equipment will be washed on-site. The washout will be located a minimum of 50 feet away from concentrated flows of stormwater, drainage courses, and inlets. Additional washouts will be utilized as needed. Washouts will be contained so that there is no discharge into the underlying soil and onto the surrounding areas.

Sanitary-Septic Waste Management WM-9 Sanitary/Septic Waste Management- A licensed service will deliver and maintain portable restrooms to the project area. The restrooms will be located away from traffic and drainage facilities on level hard-packed or paved surfaces. Portable restrooms will be contained to prevent discharges of pollutants to the stormwater drainage system or receiving water. The restrooms will be inspected regularly for cleanliness, leaks and spills. They will be cleaned and replaced when needed.

3.4 POST CONSTRUCTION STORMWATER MANAGEMENT MEASURES Post construction BMPs are permanent measures installed during construction, designed to reduce or eliminate pollutant discharges from the site after construction is completed.

The Project Owner (Riverside County Flood Control and Water Conservation District) is responsible for post-construction BMPs (inspection, long term maintenance, etc.). The Owner will identify site design, source controls and treatment controls that will be included in the permanent project as well as a funding mechanism for long term BMP maintenance as applicable. The General Permit requires that all dischargers implement BMPs to reduce pollutants in stormwater discharges that are reasonably foreseeable after all construction phases have been completed at the site. The project is located in an area subject to the requirements of the Santa Ana Regional Water Quality Control Board's Phase I Municipal Separate Storm Sewer System (MS4) Permit (Order No. R8-2010-0033) and the run-off reduction requirements therein.


Section 4 BMP Inspection and Maintenance

4.1 BMP INSPECTION AND MAINTENANCE This section is taken directly from Attachment A of the Construction General Permit.

LUP Type 1 Monitoring and Reporting Requirements

a. LUP Type 1 Inspection Requirements

iii. LUP Type 1 dischargers shall ensure that photographs of the site taken before, during, and after storm events are taken during inspections, and submitted through the State Water Board's SMARTS website once every three rain events.

iv. LUP Type 1 dischargers shall conduct daily visual inspections to verify that:

(1) Appropriate BMPs for stormwater and non-stormwater are being implemented in areas where active construction is occurring (including staging areas);

(2) Project excavations are closed, with properly protected spoils, and that road surfaces are cleaned of excavated material and construction materials such as chemicals by either removing or storing the material in protective storage containers at the end of every construction day;

(3) Land areas disturbed during construction are returned to pre-construction conditions or an equivalent protection is used at the end of each workday to eliminate or minimize erosion and the possible discharge of sediment or other pollutants during a rain event.

v. Inspections may be discontinued in non-active construction areas where soil-disturbing activities are completed and final soil stabilization is achieved (e.g., paving is completed, substructures are installed, vegetation meets minimum cover requirements for final stabilization, or other stabilization requirements are met).

vi. Inspection programs are required for LUP Type 1 projects where temporary and permanent stabilization BMPs are installed and are to be monitored after active construction is completed. Inspection activities shall continue until adequate permanent stabilization is established and, in areas where re-vegetation is chosen, until minimum vegetative coverage is established in accordance with Section C.1 of this Attachment.

b. LUP Type 1 Monitoring Requirements for Non-Visible Pollutants: LUP Type 1 dischargers shall implement sampling and analysis requirements to monitor non-visible pollutants associated with (1) construction sites; (2) activities producing


pollutants that are not visually detectable in stormwater discharges; and (3) activities which could cause or contribute to an exceedance of water quality objectives in the receiving waters.

i. Sampling and analysis for non-visible pollutants is only required where the LUP Type 1 discharger believes pollutants associated with construction activities have the potential to be discharged with stormwater runoff due to a spill or in the event there was a breach, malfunction, failure and/or leak of any BMP. Also, failure to implement BMPs may require sample collection.

(1) Visual observations made during the monitoring program described above will help the LUP Type 1 discharger determine when to collect samples.

(2) The LUP Type 1 discharger is not required to sample if one of the conditions described above (e.g., breach or spill) occurs and the site is cleaned of material and pollutants and/or BMPs are implemented prior to the next storm event.

ii. LUP Type 1 dischargers shall collect samples down-gradient from all discharge locations where the visual observations were made triggering the monitoring, and which can be safely accessed. For sites where sampling and analysis is required, personnel trained in water quality sampling procedures shall collect stormwater samples.

iii. If sampling for non-visible pollutant parameters is required, LUP Type 1 dischargers shall ensure that samples be analyzed for parameters indicating the presence of pollutants identified in the pollutant source assessment required in Section J.2.a.i.

iv. LUP Type 1 dischargers shall collect samples during the first two hours of discharge from rain events that occur during business hours and which generate runoff.

v. LUP Type 1 dischargers shall ensure that a sufficiently large sample of stormwater that has not come into contact with the disturbed soil or the materials stored or used on-site (uncontaminated sample12) will be collected for comparison with the discharge sample. Samples shall be collected during the first two hours of discharge from rain events that occur during daylight hours and which generate run off.

vi. LUP Type 1 dischargers shall compare the uncontaminated sample to the samples of discharge using field analysis or through laboratory analysis. Analyses may include, but are not limited to, indicator parameters such as: pH, specific conductance, dissolved oxygen, conductivity, salinity, and Total Dissolved Solids (TDS).

vii. For laboratory analyses, all sampling, sample preservation, and other analyses must be conducted according to test procedures pursuant to 40 C.F.R. Part 136. LUP Type 1 dischargers shall ensure that field samples are collected and analyzed according to manufacturer specifications of the sampling devices employed. Portable meters shall be calibrated according to manufacturer's specification.

viii. LUP Type 1 dischargers shall ensure that all field and/or analytical data are kept in the SWPPP document.

c. LUP Type 1 Visual Observation Exceptions


i. LUP Type 1 dischargers shall be prepared to collect samples and conduct visual observation (inspections) to meet the minimum visual observation requirements of this Attachment. The Type 1 LUP discharger is not required to physically collect samples or conduct visual observation (inspections) under the following conditions:

(1) During dangerous weather conditions such as flooding and electrical storms;

(2) Outside of scheduled site business hours.

(3) When access to the site is unsafe due to storm events.

ii. If the LUP Type 1 discharger does not collect the required samples or visual observation (inspections) due to these exceptions, an explanation why the sampling or visual observation (inspections) were not conducted shall be included in both the SWPPP and the Annual Report.

d. Particle Size Analysis for Risk Justification: LUP Type 1 dischargers utilizing justifying an alternative project risk shall report a soil particle size analysis used to determine the RUSLE K-Factor. ASTM D-422 (Standard Test Method for Particle-Size Analysis of Soils), as revised, shall be used to determine the percentages of sand, very fine sand, silt, and clay on the site.


Section 5 Training Appendix L identifies the QSPs for the project. To promote stormwater management awareness specific for this project, periodic training of job-site personnel shall be included as part of routine project meetings (e.g., daily/weekly tailgate safety meetings), or task specific trainings as needed.

The QSP shall be responsible for providing this information at the meetings, and subsequently completing the training logs shown in Appendix K, which identifies the site-specific stormwater topics covered as well as the names of site personnel who attended the meeting. Tasks may be delegated to trained employees by the QSP provided adequate supervision and oversight is provided.

3. Land areas disturbed during construction are returned to pre-construction conditions or an equivalent protection is used at the end of each workday to eliminate or minimize erosion and the possible discharge of sediment or other pollutants during a rain event.

e. Inspections may be discontinued in non-active construction areas where soil-disturbing activities are completed and final soil stabilization is achieved (e.g., paving is completed, substructures are installed, vegetation meets minimum cover requirements for final stabilization, or other stabilization requirements are met).

f. An inspection program is required where temporary and permanent stabilization BMPs are installed and are to be monitored after active construction is completed. Inspection activities shall continue until adequate permanent stabilization is established and, in areas where re- vegetation is chosen, until minimum vegetative coverage is established in accordance with Section C.A of Attachment A of the CGP. This project does not include the planting and re- establishment of vegetation.


7.4 MONITORING FOR NON-VISIBLE POLLUTANTS

7.4.1 Non-Visible Pollutant Sampling Strategy (NVPSS) As a Type 1 LUP this project is subject to the sampling requirements for non-visible pollutants. Sampling and analysis is required to determine if non-visible pollutants are present in the discharges from the construction activity and enter the receiving water. This site shall monitor non-visible pollutants associated with (1) construction sites; (2) activities producing pollutants that are not visually detectable in stormwater discharges; and (3) activities which could cause or contribute to an exceedance of water quality objectives in the receiving waters.

Sampling and analysis for non-visible pollutants is required only if the Contractor believes pollutants associated with construction activities have the potential to be discharged with stormwater runoff due to a spill or in the event there was a breach, malfunction, failure and/or leak of any BMPs. Also, failure to implement BMPs may require sample collection.

In the event non-visible pollutant sampling is required it is anticipated that the time required to perform stormwater sampling will be approximately one half hour per location. In order to complete stormwater sampling during the required time period (up to 2 hours after the start of runoff from the storm event), sufficient personnel shall be assigned to complete the task based on the number of sampling locations.

It is also anticipated that stormwater monitoring and visual observations may identify visible pollutants leaving the site, and indicate a need for action on the construction site to identify and repair failed or compromised BMPs. If necessary, additional on-call personnel will respond when action is required in the field to identify and repair failed or compromised BMPs. It is anticipated that for this project, two people will be needed to collect stormwater samples and one person will be needed on-call for as-needed response. The Contractor will be responsible to list the personnel responsible for site inspection, stormwater sampling, and as-needed response in the space provided below:

7.4.2 Identification of Potential Sources of Non-Visible Pollutants Per Attachment A of the CGP LUP Type 1 dischargers shall implement sampling and analysis requirements to monitor non-visible pollutants associated with (1) construction sites; (2) activities producing pollutants that are not visually detectable in stormwater discharges; and (3) activities which could cause or contribute to an exceedance of water quality objectives in the receiving waters.

7.4.3 Pre-Construction Activities No pre-construction activities were in place prior to the commencement of construction activities associated with this project.

7.4.4 Construction Activities During the construction process, the Contractor and Subcontractors will use a mix of heavy equipment and vehicles typical for construction activities such as; trenching, road construction, paving, and transport of construction materials. Operation and maintenance of this equipment may cause oil and grease and petroleum hydrocarbons to come into contact with stormwater.

7.4.5 Construction Materials During the construction process, many different materials will be used on-site. Table 7.1 lists various categories of construction activities as well as typical construction materials that may be used during those activities.

7.4.6 Non-Visible Pollutants to be Monitored Based on the sources of non-visible pollutants identified above, the following indicator parameters will be analyzed to determine if pollutants are being conveyed from the site by stormwater:

• pH

• Biological Oxygen Demand (BOD)

• Nitrate

• Total Dissolved Solids (TDS)

• Oil and Grease

Additional testing may be necessary based on the pollutant suspected to have entered stormwater. The analyses will be performed by an analytical laboratory that has been accredited by the California Department of Health Services Environmental Laboratory Accreditation Program (ELAP). The laboratory will be selected by the Contractor prior to the commencement of construction activities.

The following analyses may be performed in the field using field meters: pH and Turbidity. This Non-Visible Pollutant Sampling Strategy (NVPSS) assumes that field meters will not be used, and all constituents will be analyzed by an analytical laboratory. If field meters are used, the meters will be calibrated, maintained, and operated by trained staff according to the manufacturer's specifications, and calibration records will be stored at the end of this document.

The Contractor has selected and contacted the following analytical laboratory(ies) for sample analyses. (The Contractor will be responsible to list the name, address, phone number, and contact person of the selected laboratory):

Analytical laboratory:

Street:

City, State Zip Code:

Phone Number:

Contact Name:

The laboratory will provide properly cleaned and preserved (if applicable) sampling containers (bottles) for the samples, and labels on the sample bottles. The sample bottle labels will identify the analysis to be performed and any preservative contained in the bottles, and provide room for recording the sample location and time and date of collection. The laboratory will also provide chain-of-custody forms. The laboratory will conduct analyses in accordance with 40 CFR Part 136. Table 7.2 lists the EPA method numbers for the laboratory analytical methods to be used and requirements for sample collection bottles, preservatives, and holding times for the analyses. The holding time is the amount of time after collection of the sample within which the laboratory analysis must be performed.

Specific volume requirements will vary by laboratory and must be verified with the laboratory when bottles are ordered. 2Do not pre‐rinse or overfill sample containers that contain preservative.3All samples must be kept chilled to 4°C (keep samples on ice for delivery to analytical laboratory)

7.4.7 Implementation of NVPSS Sampling and analysis is required when non-visible pollutants have the potential to contact stormwater and be conveyed from the construction site by stormwater into a storm drainage system or water body. Some examples of this situation are:

• Where construction materials and compounds are stored or used such that they are in contact with stormwater.

• For construction projects that utilize soil amendments that are in contact with stormwater runoff, unless independent test data are available that demonstrate acceptable concentration levels.

• When a leakage or spill occurs prior to a storm event and is not fully contained and cleaned.

• When a leakage or spill occurs during a storm event and it cannot immediately be isolated and/or cleaned up, and the possibility of an off-site discharge exists.

• During regular inspections of stockpiles it is discovered that cover and containment BMPs have been compromised and stormwater comes in contact with the materials, and the resulting runoff discharges into a storm drain system or water body.

• If material storage BMPs have been compromised, breached, or have failed.


If the Contractor determines that none of the conditions listed above exist at the site, and the following conditions are met, stormwater sampling may not be required. However, this NVPSS will be maintained in the SWPPP and sampling equipment and bottles will be kept at the site as a contingency sampling plan to be used in the event of an incidental discharge. Under the following conditions, sampling may not be required to be implemented:

• Where a construction project is "self-contained", meaning that the project contributes no runoff to other sources or areas and that any potential discharge of pollutants can be totally contained within the construction project site without discharging to a water body or storm drain system.

• Where construction materials and compounds are kept or used so that they are not in contact with stormwater (e.g., in water tight containers, under a water-tight roof, inside a building, etc.).

• Where for specific pollutants, the BMPs implemented at the construction site fully contain the exposed pollutants (e.g., bermed concrete washout area).

• For building materials that are in their final constructed form (e.g., fence materials, support structures and equipment that will remain exposed at the completion of the project, etc.).

• Where pollutants that may have been spilled or released on-site but have been properly cleaned up and stormwater exposure has been eliminated prior to a storm event.

• For stockpiles of construction materials for which both cover and containment BMPs have been properly implemented to protect them from run-on and from contributing pollutants to stormwater runoff.

The Contractor will apply a benchmark criteria discussed below to cease stormwater sampling at outfalls where laboratory data for three consecutive rain events for the specific outfall indicates that the discharges at that outfall are below benchmarks for the analyte and no new construction activity or materials have been added in the area draining to the outfall. However, if construction activity in the area draining to the outfall changes, a spill or breach occurs within the drainage area, or a BMP in the area is observed to be compromised, the Contractor will re-institute testing at that outfall.

7.4.8 Monitoring Locations The objective of sampling direct runoff from the construction site for non-visible pollutants is to determine whether materials or activities on the site have contributed to contamination of runoff leaving the site.

The control sample is a sample of stormwater that has not come in contact with the disturbed soil or the materials stored or used on-site (''uncontaminated sample"). Uncontaminated samples may be collected from discharge locations from the construction site where activities are not occurring on the site.

The Contractor will identify the non-visible pollutant sampling locations based on the activities occurring on the jobsite which might contribute to a discharge of non-visible pollutants. Space is provided below to list monitoring locations for non-visible pollutants as applicable.


7.4.8.1 Site Sampling Locations for Non-Visible Pollutants.

The monitoring locations below represent locations where stormwater runoff has come into contact with material which has spilled or leaked at the project site.

Monitoring Location A: Immediately upstream of existing catch basins on Avenue L, approximately 150' east of 4th Street (see Site Maps Sheet 2).

Monitoring Location B:

Monitoring Location C:

Monitoring Location D:

Monitoring Location E:

7.4.8.2 Control Samples

Stormwater uncontaminated sampling locations (control locations) must represent locations where stormwater runoff has not come into contact with material which has spilled or leaked at the project site. The below locations represent the project's control sampling locations.

Monitoring Location F: Sundar/Avenue L intersection (see Site Maps Sheet 3)

Monitoring Location G: 2nd Place/Avenue L intersection (see Site Maps Sheet 7)

Monitoring Location H: Bryant Street, approximately 100' north of Avenue L intersection (see Site Maps Sheet 13)

Monitoring Location I: North of project end, on Douglas Street (see Site Maps Sheet 17)

7.4.9 Sample Collection Strategy and Schedule A sample collection schedule is not applicable to this program due to the variable nature of the weather as well as the changing construction activities occurring on-site. Stormwater runoff samples will be collected during storm events in which material has leaked or spilled or there is reason to believe the discharge of stormwater from the project may result in the discharge of non-visible pollutants regardless of the time of year or status of the construction. Sampling will be conducted during the first 2-hours of runoff, during business hours only.

7.4.9.1 Weather Tracking

Each day, the QSP shall consult the NOAA website at http://www.srh.noaa.gov for the current weather forecast. Weather reports should be printed and maintained with the SWPPP in Appendix O, "Weather Reports".

If a storm is forecasted this will trigger mobilization for non-visible pollutant stormwater sample collection. Table 7.3 describes different stages of action based on forecasted weather. Table 7.3 refers to Sections below for actions such as mobilization, sampling and post-storm event procedures.

Go Storm event has started Note time of storm event start and record on Sampling Event Worksheet. Begin storm event field visual inspection. Note time of runoff start and record on storm event worksheet. Proceed with sampling at start of runoff. Note: Only non-visible pollutant sampling is required for this project.

Post-Storm Event

Precipitation and runoff have ceased or stormwater sampling and site inspections have been completed

Demobilize and complete storm event paperwork. Monitor weather forecasts daily or weekly depending on whether further storm systems are currently developing.

7.4.9.2 Pre-Event Mobilization (Action Levels Pre-Alert and Alert)

Mobilization for stormwater sampling must begin when a storm event is predicted to occur within 48 hours. Use the following procedure to mobilize for stormwater sampling. Begin early because storms may approach faster than originally forecasted.

When a storm is predicted to occur within the next 48 hours (Pre-Alert):

1. Review inventory of stormwater sampling equipment - use Sampling Equipment Checklist.

2. If necessary, obtain any equipment that has been removed from the inventory.

When a storm event is predicted to occur within 24 hours (Alert):

1. Load the sampling equipment and paperwork into the vehicle that will be used for storm event field inspection and stormwater sampling.

2. Contact the analytical laboratory if it is anticipated that the delivery of samples may occur after the laboratory's normal business hours to arrange a late or weekend drop-off of samples.


On the day that the storm event is predicted to occur, buy ice and place the ice in the cooler.

7.4.9.2.1 Sampling Equipment

All sampling equipment will be kept on-site in an accessible location. Typical sampling equipment will include:

• Sample bottle sets appropriate to the samples that will be collected. Note all sample bottles require labels.

• New, clean sample collection containers appropriate to the sample locations, "disposable" containers for single use are preferred. This may include plastic buckets with handle and pourable lip, plastic cups, plastic dipper cup attached to pole, plastic dustpans (for collection of shallow sheet flow).

• Sampling Event Worksheet

• Visual Observation Worksheets

• Chain-of-Custody forms

• Clipboard

• Wax pencils, felt tip markers, or other appropriate writing instrument for wet conditions

• Paper towels

• Crowbar, if necessary to access cleanout or manhole

• Rope, if necessary for lowering buckets into flow

• Keys or record of lock combinations, if necessary to access sampling locations

• Any other equipment necessary for site access

• Alconox soap

• Gallon jugs of distilled water

• 5-gallon bucket or other container to carry equipment

• 5-gallon bucket to rinse sampling equipment

• Cooler(s) adequate to carry filled sample bottles

• Field meters, if applicable

When a storm event is expected to occur, ice will be purchased and stored in the cooler(s).

7.4.9.2.2 Sample Bottles

Sample bottles are to be provided by the analytical laboratory. The sample bottles require labels indicating the analysis, preservative (if applicable), and space to record the sample collection location, date and time. The laboratory must provide bottles appropriate to the expected sampling parameters, and certify that the bottles are clean. An order for bottles must be placed prior to the first mobilization of the season so that the bottles will be on hand for mobilization. Enough bottles should be ordered for multiple events in order to have plenty of bottles on hand.


Different bottles are used for different sampling parameters. Table 7.2 lists sampling parameters and appropriate bottles. Sets of bottles should be pre-assembled for the suite of analyses for each location to be sampled (i.e., for each sampling location on the project, a box or Ziploc bag containing the appropriate sample bottles for the location should be prepared in advance of sampling). The bottles may be pre-labeled with the sampling location if known.

7.4.9.3 Sample Collection and Handling

Upon the start of a sampling storm event, the personnel responsible for site inspection and stormwater sampling will begin the site inspection and proceed to the sampling points to collect samples of stormwater runoff. All necessary equipment mobilized during pre-event mobilization will be transported to the sampling locations. Samples will be collected during the first two hours of runoff from the site.

Samples will be collected manually "grab samples" by filling the bottles directly in the flow of stormwater where possible, or by dipping a bucket or other container in the flow and decanting the stormwater into the bottles. For samples that cannot be collected directly into the sample bottle, new, clean, disposable buckets or other containers will be used for each sampling location. The sample bottle or sampling container will be pre-rinsed in the flow of stormwater to be collected prior to collection of the sample, with the exception of sample bottles that contain preservatives. Bottles will be filled completely and closed tightly. If it is necessary to use the same equipment at multiple locations, the equipment will be rinsed in a bucket with Alconox soap and distilled water between sample locations.

The time and date of the sample and the sampling location will be recorded on the sample bottles. Each sample will be recorded on a chain of custody form. Samples will be placed in a cooler with ice. Concurrently with sample collection, visual observation of runoff at each sampling location will be performed. A Visual Observation Worksheet will be filled for each sampling location and storm event. Visual Observation Worksheets are provided in Appendix A. If visual observations indicate that visible pollutants are being transported from the site, appropriate personnel will be contacted to determine the source of the pollutants, contain the pollutants, and repair or replace any BMPs that are determined to have failed or been compromised.

After samples have been collected from all locations, they will be immediately transported to the analytical laboratory. Samples must be transported to the laboratory on the day of collection to ensure that the laboratory may complete the requested analyses within the required holding time (refer to Table 7.2). If sample collection will be completed outside of the analytical laboratory's normal business hours, call the laboratory in advance to arrange for a late or weekend drop-off of the samples.

The chain-of-custody form will be transported to the analytical laboratory with the samples. Upon receipt of the samples, the analytical laboratory will log in the samples received in their logbook. The sampling personnel and the analytical laboratory will sign the chain-of-custody form releasing the samples to the analytical laboratory, and the analytical laboratory will provide a signed copy of the chain-of-custody form to the person delivering the samples. If the samples are transported by a courier, the sampling personnel and the courier will sign the chain-of- custody form releasing the samples to the courier, and the courier will release the samples to the analytical laboratory by the same procedure.


7.4.9.4 Post-Storm Event Procedures

Following completion of stormwater sampling and site inspection for a storm event, all Visual Observation Worksheets and field Visual Inspection Forms will be reviewed to determine if further action is required on the site to correct any failed or compromised BMPs. Corrective actions that were taken on the site will be recorded on the Visual Observation Worksheets where visual observations indicated that action was required.

All sampling equipment will be cleaned and inspected. New bottles will be obtained to replace bottles used for sampling as necessary. Any compromised pieces of equipment will be replaced.

The Sampling Event Worksheet will be completed and filed with the Visual Observation Worksheets and the Chain of Custody forms in Appendix G of this SWPPP.

7.4.10 Analytical Data Evaluation

Typical laboratory turnaround time to return sample results ranges from 10 days to several weeks. If visual observations made during the storm event indicate that action is required in the field to correct failed or compromised BMPs, the action will be taken immediately, before sample results are received. Upon receipt of sample results, the results will be reviewed and compared with Visual Observation Worksheets and field Visual Inspection Forms to determine whether further action is required on the site to upgrade BMPs (e.g., if it is found that visual observations in the field did not indicate that action was required, but sample results exceed benchmark levels discussed below). The Contractor will be responsible to designate the person(s) responsible for this task and record the information:

Name: Phone number: If it is determined that BMPs must be upgraded based on sample results, the SWPPP will be amended accordingly and the SWPPP Amendment is to be logged in at the beginning of this SWPPP and certified by the QSD in Appendix D.

Table H.4 Benchmark Criteria for Decision Making

Analyte Benchmark Concentration Reference pH <6.5 or>8.5 Basin Plan BOD >30 mgll USEPA* Nitrate >45 mg/1 as nitrate Basin Plan TDS >500 mg/L Basin Plan Oil and Grease >15 mg/1 USEPA *United States Environmental Protection Agency Multi-Sector Industrial Permit

When laboratory analysis shows that a tested analyte exceeds the benchmark concentration, the Contractor will perform a root cause analysis. Records of any corrective action take are to be kept in Appendix G of this SWPPP.


7.4.11 Sampling and Analysis Records

All Sampling Event Worksheets, Visual Observation Worksheets, chain-of-custody forms laboratory analysis data, and other documentation relating to sampling and analysis will be kept on-site with the SWPPP, which is to remain at the construction site at all times until a Notice of Termination for the project is submitted and approved. The General Construction Permit requires that records of all inspections, compliance certifications, and non-compliance reporting must be retained for a period of at least three years from the date generated or after project completion.

7.4.12 Modification to This Procedure

The QSD will review this procedure after the first sampled storm event and periodically during its implementation, and will revise procedures as needed. Anticipated situations that may cause the QSD to revise the SWPPP or NVPSS include but are not limited to:

• Comparison of analytical results with benchmarks for analytes tested

• Changes in construction activity occurring on-site that result in changes to pollutants of concern

7.4.13 Training For Sampling Personnel

Samples will be collected by personnel trained in field sample collection and the objectives of this NVPSS. The Contractor will provide training prior to the first mobilization for stormwater sample collection.

C) LS Factor (weighted average, by area, for all slopes)

The soil-erodibility factor K represents: (1) susceptibility of soil or surface material to erosion, (2) transportability of the sediment, and (3) the amount and rate of runoff given a particular rainfall input, as measured under a standard condition. Fine-textured soils that are high in clay have low K values (about 0.05 to 0.15) because the particles are resistant to detachment. Coarse-textured soils, such as sandy soils, also have low K values (about 0.05 to 0.2) because of high infiltration resulting in low runoff even though these particles are easily detached. Medium-textured soils, such as a silt loam, have moderate K values (about 0.25 to 0.45) because they are moderately susceptible to particle detachment and they produce runoff at moderate rates. Soils having a high silt content are especially susceptible to erosion and have high K values, which can exceed 0.45 and can be as large as 0.65. Silt-size particles are easily detached and tend to crust, producing high rates and large volumes of runoff. Use Site-specific data must be submitted.

The effect of topography on erosion is accounted for by the LS factor, which combines the effects of a hillslope-length factor, L, and a hillslope-gradient factor, S. Generally speaking, as hillslope length and/or hillslope gradient increase, soil loss increases. As hillslope length increases, total soil loss and soil loss per unit area increase due to the progressive accumulation of runoff in the downslope direction. As the hillslope gradient increases, the velocity and erosivity of runoff increases. Use the LS table located in separate tab of this spreadsheet to determine LS factors. Estimate the weighted LS for the site prior to construction.

B) K Factor (weighted average, by area, for all site soils)

Analyses of data indicated that when factors other than rainfall are held constant, soil loss is directly proportional to a rainfall factor composed of total storm kinetic energy (E) times the maximum 30-min intensity (I30) (Wischmeier and Smith, 1958). The numerical value of R is the average annual sum of EI30 for storm events during a rainfall record of at least 22 years. "Isoerodent" maps were developed based on R values calculated for more than 1000 locations in the Western U.S. Refer to the link below to determine the R factor for the project site.http://cfpub.epa.gov/npdes/stormwater/LEW/lewCalculator.cfm

AGI recommends the uppermost 12 inches of soil materials below pavement

subgrades be processed and compacted to a minimum of 95 percent of the

laboratory maximum dry density determined by ASTM D 1557-09. Caltrans Class

2 aggregate base material should be compacted to a minimum of 95 percent of

maximum dry density. Pavement gradients should result in rapid and unimpaired

flows of runoff water to road shoulders and the new drainage improvements.

6.11 Soil Corrosivity

Chemical analyses were performed to provide a general evaluation of the corrosivity

of native alluvial soils. Tests included soluble sulfate and chloride ion contents, pH,

and saturated resistivity. Findings indicate the project soils should not be highly

aggressive to concrete but may be moderately corrosive to metal. Analytic tests of

3 samples of older alluvium reported peak soluble sulfate and chloride contents of

0.0029 percent and 20 parts per million respectively, with pH values of 6.7 to 7.0,

and a lowest-value saturated minimum resistivity of 3,000 ohm-cm. District

standards or a qualified corrosion engineer should be consulted for design details

and/or more in-depth evaluations of soils effects on buried ferrous objects, and for

any special corrosion protection design that may be required.

The very low sulfate concentrations indicate that normal Type I-II cement should be

suitable for concrete mix designs utilized for this project, based on American

Concrete Institute (ACI) 318 Table 4.3.1. AGI recommends that all concrete which

will contact on-site soil materials be selected, batched, and placed in accordance

with the latest Standard Specifications for Public Works Construction “Greenbook”

and ACI technical recommendations.

6.12 Soil Erosion Potential

The proposed construction will be taking place entirely within developed areas, and

will not be representative of disturbances in virgin ground. Soil erosion from local

streets is currently nil. However, some migration of soils from private property to the

streets has been observed by AGI staff during storms within the last two years.

A soil’s resistance to sheet and rill erosion is a function of textural gradation, clay

type, organic content, vegetation cover, structure of the surface horizon, and

permeability. Using data and estimations from this investigation, AGI would assign

a soil erodibility “K” factor of 0.15 to vacant bare-ground or tilled Calimesa older

alluvium per the methods of Wischmeier, Johnson and Cross (1971). For a typical

local construction site, this value would rise to roughly 0.20 considering surface

compaction and reduced infiltration capacity. Soil stockpiles would have lower “K”

factors.

Later work by the USDA distilled the Wischmeier et al. equation into a triangular

nomograph utilizing only the variables of percent silt + fine sand (0.002-0.1 mm),

percent sand (0.1-2.0 mm), and percent clay. A tested sample of near-surface

alluvium along the project alignment had about 58 percent, 34 percent, and 8

percent of these constituents, respectively, on a normalized basis minus coarser

fractions. The resulting “K” factor would be approximately 0.34. This highest-

estimated value would be conservative if needed for site risk classification in storm

water pollution plans or other water quality permit requirements.

6.13 Construction Observations

The preliminary geotechnical recommendations presented in this report are based

on the assumption that flood control improvements will be placed on competent

native materials or properly compacted engineered fill approved by this office. It is

recommended that trench backfill and street restoration operations be performed

with observation and quality control testing by AGI personnel. AGI services would

exclude direction of the contractor’s means and methods, field supervision of the

contractor’s workmen, or assumption of any responsibility for jobsite safety.

6.14 Investigation Limitations

The findings in this preliminary report may require modification as a result of later

field exploration or observations made prior to or during drain installation. If

conditions encountered during construction vary significantly from those indicated by

this report, then additional geotechnical recommendations may be required from this

LUP Flowcharts - Definition of Terms Determining if your project qualifies for coverage

State Water Board Order 2009-0009-DWQ 1. Emergency Activities – These are activities associated with responding to emergencies to protect public health and

safety and restoration of public services after natural or manmade disasters. 2. Linear Construction Activity – Linear construction activity consists of underground/ overhead facilities that

typically include, but are not limited to, any conveyance, pipe or pipeline for the transportation of any gaseous, liquid (including water, wastewater for domestic municipal services), liquescent, or slurry substance; any cable line or wire for the transmission of electrical energy; any cable line or wire for communications (e.g., telephone, telegraph, radio or television messages); and associated ancillary facilities. Construction activities associated with LUPs include, but are not limited to those activities necessary for the installation of underground and overhead linear facilities (e.g., conduits, substructures, pipelines, towers, poles, cables, wires, connectors, switching, regulating and transforming equipment and associated ancillary facilities) and include, but are not limited to, underground utility mark-out, potholing, concrete and asphalt cutting and removal, trenching, excavation, boring and drilling, access road and pole/ tower pad and cable/ wire pull station, substation construction, substructure installation, construction of tower footings and/or foundations, pole and tower installations, pipeline installations, welding, concrete and/or pavement repair or replacement, and stockpile/ borrow locations.

3. Planning/ Designing Activities – These are field activities associated with the planning and design of a project (e.g., activities associated with route selection). These could include, but are not limited to, potholing, sediment coring, and limited excavations to verify conflicts or contaminated soils.

4. Pre-Development Activities – These are construction activities associated with LUPs conducted by a discharger or its authorized representative to remove and/or relocate lines and facilities prior to the start of construction for new development and redevelopment projects that are owned or operated by third parties or municipal agencies. Soil disturbances from preconstruction projects are considered separately from the development or redevelopment projects for the purposes of determining if they meet minimum threshold requirements for areas of soil disturbance that would require coverage by a construction storm water permit.

5. Redevelopment Projects – Involve construction activities associated with LUPs constructed by the discharger to relocate lines or convert facilities from overhead to underground as a result of a redevelopment project owned or operated by a third party or municipal agency.

6. Routine Maintenance Activities – Activities associated with operations and maintenance activities that are conducted on existing lines and facilities and within existing right-of-ways, easements, franchise agreements, or other legally binding agreements of the discharger. Routine maintenance projects include, but are not limited to projects conducted to:

a. Maintain the original purpose of the facility or hydraulic capacity. b. Update existing lines1 and facilities to comply with applicable codes, standards, and regulations

regardless if such projects result in increased capacity. c. Repairing leaks

Routine maintenance does not include construction of new2 lines or facilities resulting from compliance with applicable coders, standards, and regulations. Routine maintenance does not include those areas of maintenance projects that are outside of an existing right-of-way, franchise, easements, or agreements.

7. Tie-in Activities – Activities conducted immediately adjacent to “energized” or “pressurized” facilities by the discharger or their authorized representative and are not considered small construction activities where all other LUP construction activities associated with the tie-in are covered by an NOI and SWPPP of a third party or municipal agency.

1 Update existing lines includes replacing existing lines with new materials or pipes. 2 New lines are those not associated with existing facilities and are not part of a project to update or replace existing lines.

(Date)

Good Housekeeping for Construction Materials

Inventory of products (excluding materials designed to be outdoors)

Stockpiled construction materials not actively in use are covered and bermed

All chemicals are stored in watertight containers with appropriate secondary containment, or in a completely enclosed storage shed

Construction materials are minimally exposed to precipitation

BMPs preventing the off-site tracking of materials are implemented and properly effective

Good Housekeeping for Waste Management Wash/rinse water and materials are prevented from being disposed into the storm drain system

Portable toilets are contained to prevent discharges of waste

Sanitation facilities are clean and with no apparent for leaks and spills

Equipment is in place to cover waste disposal containers at the end of business day and during rain events

Discharges from waste disposal containers are prevented from discharging to the storm drain system / receiving water

Stockpiled waste material is securely protected from wind and rain if not actively in use

Procedures are in place for addressing hazardous and non-hazardous spills

Appropriate spill response personnel are assigned and trained

Equipment and materials for cleanup of spills is available onsite

Washout areas (e.g., concrete) are contained appropriately to prevent discharge or infiltration into the underlying soil

Good Housekeeping for Vehicle Storage and Maintenance

Measures are in place to prevent oil, grease, or fuel from leaking into the ground, storm drains, or surface waters

All equipment or vehicles are fueled, maintained, and stored in a designated area with appropriate BMPs

Vehicle and equipment leaks are cleaned immediately and disposed of properly

(Date)

Good Housekeeping for Landscape Materials

Stockpiled landscape materials such as mulches and topsoil are contained and covered when not actively in use

Erodible landscape material has not been applied 2 days before a forecasted rain event or during an event

Erodible landscape materials are applied at quantities and rates in accordance with manufacturer recommendations

Bagged erodible landscape materials are stored on pallets and covered

Good Housekeeping for Air Deposition of Site Materials

Good housekeeping measures are implemented onsite to control the air deposition of site materials and from site operations

Non-Stormwater Management

Non-Stormwater discharges are properly controlled

Vehicles are washed in a manner to prevent non-stormwater discharges to surface waters or drainage systems

Streets are cleaned in a manner to prevent unauthorized non-stormwater discharges to surface waters or drainage systems.

Erosion Controls

Wind erosion controls are effectively implemented

Effective soil cover is provided for disturbed areas inactive (i.e., not scheduled to be disturbed for 14 days) as well as finished slopes, open space, utility backfill, and completed lots

The use of plastic materials is limited in cases when a more sustainable, environmentally friendly alternative exists.

Sediment Controls

Perimeter controls are established and effective at controlling erosion and sediment discharges from the site

Entrances and exits are stabilized to control erosion and sediment discharges from the site

Sediment basins are properly maintained

Linear sediment control along toe of slope, face of slope an at grade breaks (Risk Level 2 & 3 Only)

Limit construction activity to and from site to entrances and exits that employ effective controls to prevent offsite tracking (Risk Level 2 & 3 Only)


Ensure all storm, drain inlets and perimeter controls, runoff control BMPs and pollutants controls at entrances and exits are maintained and protected from activities the reduce their effectiveness (Risk Level 2 & 3 Only)

Inspect all immediate access roads daily (Risk Level 2 & 3 Only)

Run-On and Run-Off Controls

Run-on to the site is effectively managed and directed away from all disturbed areas.
