Laws, Regulations, andCompliance Documents
Laws and Regulations• Guam Administrative Rules, Title 22, Chapter 7• Guam Administrative Rules, Title 22, Chapter 6-Section 53106 of the Guam Safe Drinking Water Act-Section 6141.5 of Guam Primary & Secondary SDW Regs.• Section 438 of the Energy Independence and Security Act
DoD Compliance Documents• Unified Facilities Criteria (UFC) 3-210-10 & 3-210-10N• Dept. of Navy LID Policy for Storm Water Management
Other Standards and Guidance• CNMI and Guam Stormwater Management Manual
12/1/2010
16
Laws and Regulations
Guam Administrative Rules, Title 22, Chapter 7, Section 7130“…no person shall construct, utilize, operate, occupy or cause, allow or let, permit or suffer or to be constructed, utilized, operated or occupied any land use served or to be served by septic tank and leached field, sanitary sewer, storm water disposal method, or liquid waste storage, disposal or treatment method, and which is within the GWMPZ and within any 1,000 feet radius of any public utility potable water supply well, until the person has obtained prior written approval of the Administrator…”
Section 438 of the EISA“The sponsor of any development or redevelopment project involving a Federal facility with a footprint that exceeds 5,000 square feet shall use site planning, design, construction, and maintenance strategies for the property to maintain or restore, to the maximum extent technically feasible, the predevelopment hydrology of the property with regard to the temperature, rate, volume, and duration of flow.”
12/1/2010
17
DoD Compliance Documents
UFC 3-210-10, Low Impact Development• This UFC provides guidelines for LID planning, design, construction, and O&M• “…reduce the hydrologic impact of the development and to incorporate techniques
that maintain or restore the site’s hydrologic and hydraulic functions…”
UFC 3-210-10N, Low Impact Development• Provides technical criteria, requirements and references for the planning & design
to comply with stormwater requirements under EISA
• Maintain or restore predevelopment hydrology to the maximum extent technically feasible
• State and local standards for LID Integrated Management Practices (IMP) design shall be used if available.
12/1/2010
18
CNMI and Guam Stormwater Management Manual
• Provides minimum criteria for BMPs that are acceptable for meeting construction & post-construction stormwater criteria and water quality treatment goals
• Specifies that infiltration of stormwater runoff from “hotspots” is not allowed without prior water quality treatment, and that a Stormwater Pollution Prevention Plan (SWPPP) must be prepared and implemented for “hotspots” to reduce the generation of pollutants and prevent contact of rainfall with the pollutants.
• The Navy has made a commitment with GEPA to comply with this document in anticipation of the adoption of Guam’s updated Erosion Control and Stormwater Management Regulations into Guam’s new regulations.
12/1/2010
19
What does all this mean?
• Need to protect Guam’s water resources• Need Guam EPA’s approval for water systems (siting approvals
and design approvals)• Need Guam EPA’s approval for sewer system (design approvals)• Need Guam EPA’s approval for wellhead protection• Need to pay special attention to projects inside the 1,000’ circles*especially for “high risk” land uses/activities
• Follow standards and guidelines in the 2006 CNMI & Guam SWMM
• Follow DoD Low Impact Development policies

Overall Stormwater Management & Compliance Strategy

Planning
Design
Operations/ Maintenance
21
Planning Phase
Mitigation Strategies
• Relocate certain types of activities (entire or pollutant-generating part) outside of WHPA
• Convey and infiltrate runoff outside WHPA
• Consider relocating certain wellhead(s) (possible example: low producing well with high chlorides) or consider shutdown of certain wellheads or designating them for non-potable use
12/1/2010
22
Planning: Categories of proposed“High Risk” Activities that encroach into WHPAs
12/1/2010
A. Vehicle fueling stations
B. Vehicle service and maintenance facilities
C. Vehicle and equipment cleaning facilities
D. Outdoor loading/unloading facilities
E. Facilities that generate or store hazardous materials and/or liquid or solid waste
F. Stormwater disposal facilities
G. Dining facilities / food preparation
H. Engineering Training Pit
*Also we need to pay special attention to parking lots
23
Design Phase – LID Site Design
LID Site Design strategies reduce the hydrologic impact of development and incorporate techniques that maintain or restore the site’s hydrologic and hydraulic functions to pre-project conditions. Strategies include:
• Reduce amount of impervious areas
• Disconnect impervious areas
• Direct runoff into or across vegetated areas
• Preserve, or design into the infrastructure, naturally vegetated areas that are in close proximity to parking areas, buildings, and other impervious expanses in order to slow runoff, filter out pollutants, and facilitate infiltration
**Taking care of water “at the source” instead of the traditional “end of pipe” approach using small scale approaches or Integrated Management Practices (IMPs)**
12/1/2010
24
Design Phase – BMP/IMP &Treatment Trains
12/1/2010
Pollutants of concern:• TSS• Nutrients (TN and TP)• Metals• Bacteria• Hydrocarbons
BMP/IMP Treatment Trains are multiple treatment devices operatingin series designed to remove specific pollutants of concern.
* Finegayan Main Cantonment Area Comprehensive Drainage and Low ImpactDevelopment Implementation Study Final Report (April 2010)
Applicable BMPs/IMPs*:• Proprietary oil/grit separator; Filter Strip, Dry Swale, Bioretention
Basin, TSS filter Chamber, Inlet Protector, Rain Barrel / Cistern
Treatment Trains developed for*:• Roof Runoff• Impervious paved areas w/insignificant oil or suspended metals• Impervious paved areas w/significant oil or suspended metals• Impervious paved roadways with insignificant oil or suspended
metals• Landscaping, grass and recreational areas• Site-Optional porous pavement (non-vehicle)
25
Design Phase – Source Control BMPs
Source Control BMPs are low-technology practices designed to prevent pollutants from contacting runoff or to prevent discharge of contaminated runoff to the storm drainage system, such as:
• Include an overhanging roof structure or canopy over fuel dispensing areas, vehicle wash areas, and outdoor work areas
• Pave fuel dispensing areas, repair/maintenance floor areas, hazardous material or waste storage areas, and loading/unloading areas with Portland cement concrete instead of asphalt concrete
• Slope/grade/berm fuel dispensing areas, vehicle wash areas, outdoor repair bays, and material storage areas to prevent ponding and run-on
• Prevent spilled materials and wash-down waters from repair bays from entering the storm drain system.
• Install sumps to collect wash water from cleaning facilities or loading/unloading areas
12/1/2010
26
Operations and Maintenance Phase
Industrial SWPPP
• Be in compliance with NPDES regulations
• Identify potential stormwater pollution sources
• Implement & maintain stormwater control measures
• Procedures to follow to comply with MSGP or state general industrial stormwater permit
Components of Industrial SWPPP
• Stormwater pollution prevention team
• Site description
• Summary of potential pollutant sources
• Description of control measures
• Schedules and procedures
• Documentation to support eligibility considerations under other federal laws
• Certification of the SWPPP
12/1/2010
27
Operations and Maintenance Phase (cont.)
General Guidelines for O&M• Prevent pollution
• Minimize exposure
• Combine controls
• Examine site pollutant sources
• Maximize infiltration
• Use existing vegetated areas
• Buffer on-site or adjacent waterbodies or drainage systems
• Use structural practices (as applicable)
• Implement good procedures and practices
• Worker awareness & education12/1/2010
