1.0 STORMWATER SITE PLAN SUMMARY
This Stormwater Site Plan outlines the applicable drainage regulations and presents supporting
calculations to demonstrate that the proposed stormwater system complies with the Whatcom
County Code (WCC) Chapter 20.80.630 Stormwater and Drainage and in accordance with the
2012 Stormwater Management Manual for the Western Washington, 2014 amendment (DOE
Manual or Manual). In addition, a SEPA application/determination and the Wetland Mitigation
Report prepared by AECOM will indicate further requirements for this project. This stormwater
site plan is supplemental documentation to the other submitted project plans and applications.
The Green Apple Renewable Fuels, LLC Green Apple project is a partnership between
Renewable Energy Group (REG) and Phillips 66 (P66) to develop a co-located renewable
synthetic fuels plant inside the refinery fence at P66’s Ferndale Refinery; refer to Figures 1 and
2. Green Apple will produce renewable diesel and liquid co-products—naphtha and liquefied
petroleum gas (LPG). Some storm runoff from the proposed rail area will be sent to the P66
Ferndale Refinery for further processing at the onsite wastewater treatment plant (WWTP). The
Green Apple project will be designed to operate jointly with the refinery.
The proposed project involves two separate areas within the refinery boundary where
improvements are planned:
• Inside Battery Limits (ISBL). This is the new process unit to be developed in an existing
open area in P66 Ferndale Refinery’s northeast property. This scope is being developed by
Worley.
• Outside Battery Limits (OSBL). This is the additional infrastructure required for the project
outside of the new processing unit. This scope is being developed by Anvil Corporation and
includes the following:
- Proposed Rail Facility: Expansion of the rail rack and storage track area in the northwest
corner of the refinery, including rail lateral, storage tracks, and unloading rack. The rail
improvements layout is still being defined, and current design may be revised.
- Inside Refinery Improvements: Additional tankage building modifications, process
equipment areas, and piping systems.
The ISBL and OSBL areas drain to different discharge points and will have separate stormwater
plans. The focus of this report is on the OSBL project area.
The OSBL has two distinct stormwater discharge conditions. The OSBL inside plant
improvements stormwater will discharge to the existing refinery sewer system and pass through
the refinery wastewater treatment plant prior to offsite discharge. The proposed rail facility
expansion will have two distinct stormwater discharge locations. The proposed rail facility
expansion unloading rack area and storage track area will be routed to the refinery sewer system.
The incoming lateral track area drainage and upland drainage will be routed to the wooded area
west of the developed refinery to an existing stormwater outfall.

STORMWATER SITE PLAN
REG092/P66 18030 PAGE 2 of 18 ISSUE FOR PERMIT, REVISION A ANVIL 108976 NOVEMBER 21, 2019
The Phillips 66 Ferndale Refinery has been issued a National Pollutant Discharge Elimination
System Permit (No. WA0002984) (NPDES Permit) by the Washington State Department of
Ecology that provides the regulatory requirements for the discharge of stormwater offsite and
into the waters of the state. This permit issued March 11, 2014, and effective April 1, 2014,
requires the update and implementation of a site-specific Stormwater Pollution Prevention Plan
(SWPPP). This plan establishes the Best Management Practices (BMPs) and the pollution
prevention project team requirements necessary to identify, reduce, eliminate, and/or prevent the
discharge of stormwater pollutants in compliance with this NPDES Permit. The SWPPP portion
of this site plan addresses only the stormwater discharges that are independent of the site’s
wastewater treatment system.
2.0 PROJECT LOCATION AND BASIN AREA
The project is located within Phillips 66 Refinery, 3901 Unick Road, Ferndale, Washington, in
Whatcom County. The subject basin areas are on the south side of Unick Road, which drains
southward towards Georgia Strait. The project site latitude and longitude coordinates are as
follows:
• 48.833° N
• 122.693° W
Additional project information includes the following:
• The project’s parcel number is 390133197340.
• The land use designation is HII – Heavy Impact Industrial.
• The project is inland from any shoreline land-use designations/restrictions.

3.0 SOILS ANALYSIS INFORMATION
The drainage Manual requires large development drainage plans to include a soil analysis if
existing soils information is not adequate. This report used information from the Web Soil
Survey (WSS), which provides soil data and information produced by the National Cooperative
Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and
provides access to the largest natural resource information system in the world
(http://websoilsurvey.sc.egov.usda.gov/App/WebSoilSurvey.aspx).
Soils information at the project site is described in the Soil Survey of Whatcom County Area,
Washington, published by the NRCS. Soils underlying the project site are composed of the
Whitehorn silt loam (#184) soil series with Urban Land (#171), Kickerville silt loam (#79 & 80),
and Birchbay silt loam (#12, 13, and 14) located along the perimeter of the site. The soils are
classified as Hydrologic Group C/D soils. Appendix B of this report contains copies of the
NRCS soils boundary map, soil descriptions, and a table with the hydrologic group classification.
Also, see the figure below for a summary view.

Figure 6. Soils Information
For the purpose of drainage characteristics, the soil is assumed to be Group C per the Web Soil
Survey (WSS) and Group C for the Western Washington Hydrology Model (WWHM) software
per guidance and modelling instructions provided with the program. These soils are
Glaciomarine Drift deposits composed of low permeability pebbly, sandy clay that will have a
very slow infiltration rate when thoroughly wet and a high runoff potential. These soils consist
chiefly of silty clays that have a high shrink-swell potential, soils that have a high-water table,
soils that have a clay pan or clay layer at or near the surface, and soils that are shallow over
nearly impervious material. These soils have a very slow rate of water transmission.
4.0 GEOTECHNICAL ANALYSIS
Section III-3.2.1 of the Manual requires large development drainage plan to include a
geotechnical analysis when:
• Grading or the construction of stormwater facilities is proposed with 200 ft of slopes steeper
than 15%;
• The County deems that the proposed construction poses a potential hazard due its proximity
to a geologically hazardous area or aquifer recharge area.
These conditions do not apply to the project, and a geotechnical analysis is not included in this
drainage plan. A geotechnical report will be prepared later for the design of supporting
structures, walls, and berms to satisfy the building code requirements.
5.0 PROJECT LAYOUT – OSBL
The project has two stormwater discharge conditions:
• The natural wooded area to the west of the proposed rail facility (west of M Street)
• The refinery sewer system, which is routed to the refinery wastewater treatment facility

STORMWATER SITE PLAN
REG092/P66 18030 PAGE 7 of 18 ISSUE FOR PERMIT, REVISION A ANVIL 108976 NOVEMBER 21, 2019
The primary focus of this report is the storm water routed to woodland area to the west of the
proposed rail facility. Other proposed improvements’ storm water will be routed to the refinery
sewer system. Figure 7 is the existing stormwater site plan. Figure 8 is the proposed stormwater
site plan
Referring to Figure 7 below , the area for the rail improvements is currently an open grassy field
east of K Street and north of 2nd Street. The existing truck rack portion generally drains southerly
towards existing catch basins that are connected to the refinery sewer system. The remainder of
the site generally drains westerly in an existing ditch and culvert system to an existing outfall in
the woodland area west of K Street. This area will be referred to as the rail area upland basin.
Stormwater runoff generated for the proposed facility unloading racks and storage track area will
be directed to the existing refinery sewer system.
Figures 9 and 10 show the WWHM modeled basins for the predeveloped and developed rail area
basin. The project will reduce the rail upland area basin by approximately 2.5 acres. The area
that will be routed to the refinery sewer system was not modeled for this report.

6.0 COMPLIANCE WITH MINIMUM REQUIREMENTS
In accordance with Whatcom County Code Section 20.80.630, this site, as an industrial area, is
considered a High Land Use Intensity for stormwater management. Therefore, Minimum
Requirements (MR) 1 through 9 from the Manual for redevelopment apply and are discussed in
the subsequent sections of this report.
• MR1: Preparation of Stormwater Site Plan
• MR2: Construction Stormwater Pollution Prevention (SWPP)
• MR3: Source Control of Pollution
• MR4: Preservation of Natural Drainage Systems and Outfalls
• MR5: Onsite Stormwater Management
• MR6: Runoff Treatment
• MR7: Flow Control
• MR8: Wetlands Protection

6.2 MR2: Construction Stormwater Pollution Prevention Plan
The Stormwater Pollution Prevention Plan (SWPPP) is included in the construction drawings;
see list in Appendix C. This Plan provides erosion and sediment control information, locations
where Best Management Practices (BMPs) must be implemented, and requirements that the
contractor must follow throughout construction.
6.2.1 Rail Facility Improvements
At the start of and during the construction phase of the project, erosion and sediment control
measures will be implemented. The project contractor will provide their own certified erosion
and sediment control lead (CESCL) who will be monitoring the site and working with the project
coordinator and a Green Apple Renewable Fuels, LLC stormwater representative to ensure site
stormwater discharges are in accordance with requirements. The construction stormwater will be
routed to a temporary pond that will provide some initial sediment trapping. The collected storm
water from this pond will then be discharged to a dispersion piping system in the woodlands west
of M Street for vegetation filtration.
The anticipated construction sequence is as follows:
• Step 1: Install high visibility fence around wetland 25-ft buffer. Install compost berm, silt
fence, or straw wattles around the site and install construction entrances.
• Step 2: Construct the sediment pond and sump pump connecting force main to vegetation
filter distribution system.
• Step 3: Construct erosion measures around topsoil stockpile area, catch ditches, ditch to
sediment settling area, access road, etc.
• Step 4: Separate topsoil from other excavated material (approximately first 12 inches of
excavation) and haul to stockpile site.
• Step 5: Begin clearing for the sediment pond area first and then move on to the remainder of
the site. Haul topsoil to stockpile and haul remainder to project disposal site.
• Step 6: Continue constructing the remainder of the project. Consider sequencing these pad
excavations so that when one is ready, gravel can quickly be placed and limit how much soil
could be tracked around the site or beyond.
• Step 7: Cover disturbed soils with straw and hold in place. Cover the topsoil stockpile(s) with
plastic sheets and secure them for the construction duration. (BMP S429)
• Step 8: Maintain all the above measures and any others provided throughout the construction
period.
• Step 9: Remove all measures when construction is completed and implement any final
permanent measures. (See Appendix C.)
6.2.2 Refinery Area OSBL
Additional construction stormwater measures may be required for work sites within the refinery.
The tank construction sites currently drain to existing catch basins connected to the refinery
sewer system. The refinery construction sites will be drained to the refinery sewer system and
will not be discharged off site.

6.3 MR3: Source Control of Pollution – Rail Facility
The drainage Manual requires large development to provide stormwater source controls to
prevent runoff from coming into contact with pollutants. The applicable Manual BMP is S422
BMPs for Railroad Yards. S422 summarizes the applicable source control treatment as follows:
The rail rack area for loading and unloading rail cars will have concrete aprons to capture,
contain, and direct any spills around the rail cars to the existing sewer system and onsite
treatment facility. The storage track area east of K Street will be on ballast and gravel backfill
that will have perforated pipe subdrains. These subdrains will also be routed to the refinery sewer
system. Current refinery procedures for handling materials will be implemented and maintained.
The lateral tracks to the west of K Street are not considered to require source control BMPs.
These tracks will not be used for storage tracks, rail car unloading, or rail equipment
maintenance.
6.4 MR4: Preservation of Natural Drainage Systems and Outfalls – Rail Facility
The proposed drainage system design for the rail facility will continue to use the existing
drainage outfall to the west for the area upland of the storage and unloading tracks. There will be
some diversion of the existing site drainage from the existing basin to the refinery sewer system.
The project is not anticipated to cause significant adverse downstream impacts.
The figure below shows the stormwater drainage system in the vicinity of the frail facility project
site. The runoff sheet flows towards the existing ditches where it is captured, conveyed under the
rail and roadway, conveyed westerly, discharged into Wetland “E” and continues overland
draining into Georgia Strait. The ditches and culverts are currently operating sufficiently, and no
deficiencies have been reported or observed. There are no known conveyance system capacity
problems or localized flooding of downstream areas. There are no known upland erosion
impacts, and no impacts due to development are anticipated.

REG092/P66 18030 PAGE 13 of 18 ISSUE FOR PERMIT, REVISION A ANVIL 108976 NOVEMBER 21, 2019
6.5 MR5: Onsite Stormwater Management – Rail Facility
The drainage Manual requires that developments provide onsite conveyance facilities (ditches,
pipes, etc.) to convey without flooding or otherwise damaging existing or proposed structures for
a peak runoff rate from the 100-year 24-hr storm event. The conveyance system is still under
design development at this time. The discharge to the existing rail area outfall will be reduced
due to the reduction in the basin area. See sections for Minimum Requirement 7 (Flow Control)
and Minimum Requirement 8 (Wetlands Protection).
6.6 MR6: Runoff Treatment – Rail Facility
The drainage Manual requires large development to provide stormwater quality control for large
area improvements where applicable. As stated in Section 6.3, rail facility areas that potentially
could release pollutants will have storm water routed to the refinery sewer system. All the paved
(concrete unloading pad and modified truck loading area) developed area will be directed to the
refinery sewer system so there is no need for additional treatment BMPs. The area where rail
cars are being stored has a layer of gravel and gravel ballast about two feet thick. Runoff from
this area will percolate through the gravels to perforated lines placed to collect this water and
will be connected to the refinery sewer system.
The incoming trackage to the west of K Street was assessed using the Manual Treatment Facility
Selection Flow Chart (Figure 13). Interpretation of this flow chart indicates that flow control
BMPs will not be required for the rail upland basin area.

6.7 MR7: Flow Control – Rail Facility
The Manual requires large development peak flow rates to match or be less than the pre-
development peak flows for the 10- and 100-year events. In addition, the design is required to
match the 2-year storm event to 50% of the pre-development flow. Additionally, the area serves
to feed some downstream wetlands. Balancing and maintaining the runoff releases to the
wetlands will take priority with these project outflows. (See report section addressing Minimum
Requirement 8 – Wetlands Protection.)
The flow control analysis was conducted using the Western Washington Hydrology Model
WWHM 2012. The point of compliance (POC 1) is the stormwater discharge to the existing
culvert crossing the rail laterals. The WHMM model was used to assess the flow frequency and
flow duration. The WWHM model results are summarized below. See Appendix A for the
WWHM report.
The rail car loading/unloading and the storage track area will be directed to the refinery sewer
system. This removes approximately 2.5 acres of developed flow from the rail area upland basin.
The final rail upland basin area runoff is reduced by approximately 11% from the pre-developed
conditions as shown in Figure 14.

6.8 MR8: Wetlands Protection – Rail Facility
In addition to MR 6 (Runoff Treatment) and MR 7 (Flow Control), the Manual also requires
additional analysis for protection of wetlands. The upland rail basin portion of the project
discharges into a downstream Category III wetland area (Wetland “E”) This area has been
preliminarily assessed for wetlands, and the project biologist is in the process of conducting
additional field work and will be preparing a critical areas report for the area (AECOM). The
proposed design is being reviewed by the project wetlands biologist (AECOM). They will
continue to review this design and offer comments when changes are proposed.
Wetlands impacted within the project area upland area will be mitigated. The mitigation plans
are not part of this report.
The Manual Appendix I-D: Guidelines for Wetlands when Managing Stormwater was applied to
the proposed stormwater system design. The guidelines are presented as a series of Guide Sheets.
These are addressed in sequence below:
6.8.1 Guide Sheet 1: Criteria that exclude wetlands from serving as a treatment or flow
control BMP/facility
These criteria specifically require that Category I wetlands, Category II wetlands, and wetlands
that provide habitat for threatened or endangered species meet the requirements of Guide Sheet
3.
6.8.2 Guide Sheet 2: Criteria for including wetlands as a treatment or flow control
BMP/facility
Category IV and Category III wetlands with a habitat score of 19 points or less can potentially be
used for stormwater treatment or flow control. Currently the project is not proposing to use the
downstream wetlands for treatment or flow control.
6.8.3 Guide Sheet 3A: General guidelines for protecting function and values of wetlands
The project plan is consistent with the requirements for protecting the functions and values of
Wetland “E” including:
• Maintain wetland buffer.
• Retain areas for native vegetation, connecting the wetland and its buffer with nearby
wetlands and other continuous areas of native vegetation.
• Avoid compaction of soil and introduction of exotic plant species.
• Do not produce general urban impacts.
• Make no modifications to the wetland inlet.
6.8.4 Guide Sheet 3B: Protecting wetlands from impacts of changes in water flows
This guide requires that increases or decreases in total flow (volume) to Category I, Category II,
and some Category III wetlands are within the following limits:
• Criterion 1: Total volume of water into a wetland during a single precipitation event should
not be more than 20% higher or lower than the per-project volumes.
GREEN APPLE RENEWABLE FUELS, LLC GREEN APPLE PROJECT: OSBL
STORMWATER SITE PLAN
REG092/P66 18030 PAGE 17 of 18 ISSUE FOR PERMIT, REVISION A ANVIL 108976 NOVEMBER 21, 2019
• Criterion 2: Total volume of water into a wetland on a monthly basis should not be more than
15% higher or lower that the per-project volumes.
The WWHM model was used to analyze the volume variance between the pre-development
condition and the post-development condition. The model results were that the post-development
volume flowrate was reduced by 11% from the pre-development flow rate, which means the
proposed project meets the requirements of Guide Sheet 3B.
6.8.5 Guide Sheet 4: Jurisdictional planning for wetlands and stormwater management
This guideline is for local jurisdictional planning and management policies. This is not
considered to be an issue that needs to be addressed by this report. The project biologist will be
preparing a report addressing the wetlands impacted by the project.
6.9 MR9: Operations and Maintenance – Rail
Phillips 66 Ferndale Refinery (property owner) and Green Apple Renewable Fuels, LLC
(operations leaseholder) will be responsible for operating and maintaining these facilities in
order to meet County and State requirements. Refinery procedures will be in alignment with their
NPDES permit requirements. No operation and maintenance manual is provided in this submittal
package.
7.0 EASEMENTS, TRACTS, AND COVENANTS
The drainage Manual requires that easements be provided for stormwater and drainage
conveyance systems that are not located in public right-of-way. The project is within the P66
property and not accessible without a P66 personnel escort. Similar to other stormwater
management systems on site, the proposed facilities will be regularly monitored by P66’s
stormwater management personnel and maintained as required. This will all be done in
accordance with the requirements of P66’s individual NPDES stormwater permit. It is assumed
that additional easements are not required for this project.
8.0 BOND QUANTITIES WORKSHEET
Whatcom County Public Works will not require a performance bond (or other financial
guarantee) for proper construction and operation of construction site BMPs. Therefore, a bond
quantities worksheet is not required at this time.

PrefaceSoil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?cid=nrcs142p2_053951).
Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

How Soil Surveys Are MadeSoil surveys are made to provide information about the soils and miscellaneous areas in a specific area. They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity.
Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA.
The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape.
Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries.
Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil
5
scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research.
The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas.
Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape.
Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties.
While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil.
Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date.
After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and

identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

Map Unit DescriptionsThe map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area. The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas

are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas.
An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.
