Introduction and Background
1.1 Purpose and Scope of this Manual
Caltrans has a commitment to prevent pollution in stormwater runoff from Caltrans properties, facilities, and activities. This manual is part of Caltrans’ comprehensive and coordinated statewide effort to prevent pollution in stormwater runoff from Caltrans construction sites.
This document guides Contractors and Caltrans staff through the process of preparing a Water Pollution Control Program (WPCP). Prior to June 2021, the WPCP Template was Microsoft Access based; in June, the template was modified to a FileMaker Pro platform. The organization of this Manual is shown below. Working details and instructions for the implementation of construction site Best Management Practices (BMPs) are presented in the Standard Plans, Contract Plans, Standard Specifications and Contract Special Provisions. The Caltrans Construction Site Best Management Practices Manual should be used as guidance for temporary construction site BMPs.
• Section 1 provides the purpose and scope of this Manual and background information on the National Pollutant Discharge Elimination System (NPDES) regulations including the Caltrans Statewide NPDES Permit.
• Section 2 provides general information of the determination of site Best Management Practices (BMPs).
• Section 3 provides detailed instructions for the preparation of a WPCP. • Section 4 provides step-by-step WPCP Builder instructions for accessing, printing, editing a WPCP using FileMaker Pro.
• Section 5 covers the actual input descriptions and instructions for the development of the WPCP for projects in Caltrans right-of-way.
• Section 6 provides step-by-step instructions for preparing WPCP Attachments A–D. • Section 7 provides Appendices A through H, Caltrans CEM forms used to document and report information necessary for WPCP implementation.
• Appendix A provides definitions of terms used throughout this Manual. • Appendix B provides a list of standard Caltrans Construction Site BMP symbols to be used on Water Pollution Control Drawings (WPCDs).
1.2 Federal Regulations
Federal regulations for controlling discharges of pollutants from municipal separate storm sewer systems, construction sites, and industrial activities, were brought under the NPDES permit process by the 1987 amendments to the Clean Water Act (CWA), and the subsequent 1990 promulgation of federal stormwater regulations issued by the U.S. Environmental Protection Agency (USEPA). The USEPA regulations require municipal and industrial stormwater discharges to comply with an NPDES permit. In California, the USEPA delegated authority to issue NPDES permits to the State Water Resources Control Board (SWRCB) and the nine Regional Water Quality Control Boards (RWQCBs).
Water Pollution Control Program (WPCP) Preparation Manual Section 1 1-2
1.3 Caltrans Statewide NPDES Permit
The SWRCB issued a Statewide Stormwater NPDES Permit (Caltrans Permit) to Caltrans, to regulate stormwater and non-stormwater discharges from Caltrans properties and facilities, and discharges associated with operation and maintenance of the State highway system. The Caltrans Permit contains three basic requirements:
1. Caltrans must comply with the requirements of the Construction General Permit (CGP) or the Lake Tahoe CGP for construction projects that have an acre or more of soil disturbance;
2. Caltrans must implement a year-round program in all parts of the State to effectively control stormwater and non-stormwater discharges; and
3. Caltrans stormwater discharges must meet water quality standards through implementation of permanent and temporary (Construction Site) BMPs and other measures.
Copies of the Caltrans Permit can be downloaded from the SWRCB website, at:
http://www.waterboards.ca.gov/water_issues/programs/stormwater/caltrans.shtml For construction projects, the Caltrans Permit requires projects to obtain coverage for stormwater discharges associated with construction activities under Order No. 2009-0009- Division of Water Quality (DWQ) Statewide Construction General Permit (CGP) and associated amendments (Order No. 2010-0014-DWQ and Order No. 2012-0006-DWQ), or for construction projects within the Lake Tahoe Hydrologic Unit the Caltrans Permit requires Caltrans to obtain coverage for stormwater discharges associated with construction activities under the Lake Tahoe Construction General Permit (LTCGP) Order No. RGT-2011-0019 NPDES No.
CAG616002. This manual does not intend to include all permit requirements. For more information and a complete listing of all requirements, refer to the Caltrans Permit, the CGP or the LTCGP.
This Manual only covers projects that disturb less than an acre of soil and require the preparation and implementation of a Water Pollution Control Program (WPCP). Table 1-1 shows where Caltrans Permit requirements are incorporated into the WPCP.

1.3.1 Qualifications for Certification and Training Requirements The CGP and the LTCGP require certification and mandate that all persons responsible for implementing the requirements of the CGP and the LTCGP meet appropriate training. Caltrans has taken those requirements and made them similar for Water Pollution Control Program work.
Water Pollution Control Program (WPCP) Preparation Manual Section 1 1-3
Training should be both formal and informal and occur on an ongoing basis. Training should include those provided by recognized governmental agencies or professional organizations.
1.3.1.1 Qualifications for Certification Requirements
For Caltrans projects, the Standard Specifications Section 13-1 outline the certification requirements for the developer of the WPCP and the WPCM who implements the approved document. This function can be performed by the same person or not; but they each must meet the minimum requirements. The WPCP must be written and certified by a person who at a minimum must have the qualifications of a QSP. The WPCP implementation must be under the supervision of the WPC Manager who also must be at a minimum a QSP.
1.3.1.2 Training Requirements
Caltrans requires water pollution control (WPC) training for project managers, supervisory personnel, subcontractors, and employees. Employees involved in WPC work must be trained in stormwater BMP implementation, maintenance standards and repair.
All employees, including subcontractor’s employees, must be trained in the following subjects:
• Water pollution control rules and regulations
• Implementation and maintenance for:
− 2.1. Temporary Soil Stabilization
− 2.2. Temporary Sediment Control
− 2.3. Tracking Control
− 2.4. Wind Erosion Control
− 2.5. Material pollution prevention and control
− 2.6. Waste management
− 2.7. Non-stormwater management
WPC training must be completed prior to working on the job.
Caltrans contract specifications require that the Contractor conduct ongoing weekly training meetings that cover:
• WPC BMPs deficiencies and corrective actions,
• BMPs that are required for work activities during the week, • Spill prevention and control,
• Material delivery, storage, use, and disposal,
• Waste management, and
• Non-stormwater management procedures.
In addition, Caltrans requires the WPCM and the alternate/substitute WPCM as well as an assistant (if one is assigned) to complete the Caltrans 8-hour WPCM training.
1.3.2 Risk Determination Requirements
1.3.2.1 Rainfall Erosivity Waiver
Projects that have a disturbed soil area (DSA) between one (1) and less than five (5) acres may qualify for a rainfall erosivity waiver under the CGP if the rainfall erosivity factor (R factor) is less than a value of 5. The R factor takes into account project location, length of construction period, Water Pollution Control Program (WPCP) Preparation Manual Section 1 1-4
and time of year, so projects that begin and complete construction within a short period are likely to qualify for a rainfall erosivity waiver.
Projects that qualify for a rainfall erosivity waiver do not need to prepare a SWPPP but must file proper permit registration documents (PRD) via SMARTS. In addition, a WPCP must be prepared by the Contractor as outlined in Section 3 of this Manual.
The R factor is calculated using the EPA Rainfall Erosivity Calculator at:
http://water.epa.gov/polwaste/npdes/stormwater/Welcome-to-the-Rainfall-Erosivity-FactorCalculator.cfm
1.3.2.2 Visual Site Monitoring
All CGP projects are required to conduct quarterly non-storm water visual site monitoring inspections.
The WPC Manager must maintain on-site records of all visual observations, personnel performing the observations, observation dates, weather conditions, locations observed, and corrective actions taken in response to the observations.
1.3.2.3 Training Documentation
Documentation of all training for individuals responsible for activities associated with BMP installation, inspection, maintenance, and repair must be included. Additionally, training and training documentation is required for individuals that are responsible for overseeing, revising, and amending the SWPPP. Training material includes documentation of informal and formal training conducted by the WPC Manager, QSD, QSP, or a qualified trainer. Documentation for informal on-site training should include: topics covered, time, date, attendees, and trainer name. 2-1
Determination of Construction
Site Best Management Practices
This section provides instructions for the determination of some construction site BMPs. The Caltrans Construction Site BMPs Manual should be used as guidance for determining project construction site BMPs. It is important to note that the requirements of this Section are based on Caltrans minimum requirements and that contract special provisions and plans may impose more stringent requirements on a project-by-project basis. Any changes to the BMP implementation after approval of the WPCP will require updating or amending the WPCP.
2.1 Definitions
2.1.1 Stormwater Discharge
Stormwater discharges consist only of those discharges that originate from precipitation events.
Stormwater is defined in the CFRs (40 C.F.R. § 122.26(b)(13)) as stormwater runoff, snowmelt runoff, and surface runoff and drainage. During precipitation events, stormwater picks up and transports pollutants into and through MS4s and ultimately to waters of the United States.
2.1.2 Non-Stormwater Discharge
Non-storm water discharges consist of all discharges that do not originate from precipitation events. Generally, non-stormwater discharges to an MS4 are prohibited, conditionally exempt from prohibition, or regulated separately by an NPDES permit. The categories of conditionally exempt non-stormwater discharge are specified at 40 CFRs section 122.26(d)(2)(iv)(B)(1).
Non-stormwater discharges that are regulated by a separate NPDES permit are not subject to the discharge prohibition. Prohibited non-stormwater discharges include conditionally exempt discharges that are found to be a source of pollutants to waters of the United States. Illicit discharges must also be prohibited. An illicit discharge is defined in 40 CFRs section 122.26(b)(2) as "any discharge to a municipal storm sewer that is not composed entirely of storm water except discharges pursuant to an NPDES permit (other than the NPDES Permit for discharges from the MS4) and discharges resulting from firefighting activities." Provision B of the Caltrans Permit addresses non-storm water discharge. Non-storm water discharges to an MS4 with a discharge to an Areas of Special Biological Significance (ASBS) are subject to a different set of conditions as stated in Finding 22.a of the Caltrans Permit.
2.1.3 Disturbed Soil Area
DSAs are areas of exposed, erodible soil that are within the construction limits and that result from construction activities. The following are not considered DSAs:
• Areas where temporary soil stabilization, erosion control, or slope protection have been applied and associated drainage facilities are in place, functional, and stabilized. • Roadways, construction roads, access roads or contractor's yards that have been stabilized by the placement of compacted sub-base, base material, or paved surfacing.
Water Pollution Control Program (WPCP) Preparation Manual Section 2 2-2
• Areas where construction has been completed in conformance with the contract plans and permanent erosion control is in place and functional or permanent vegetation is established. • For areas without permanent hard covers, soil stabilization is considered functional when a uniform vegetative cover equivalent to 70 percent of the native background vegetation coverage has been established or equivalent stabilization measures have been employed.
2.1.4 Active Areas and Inactive Areas
Active Areas are construction areas where soil-disturbing work activities have occurred at least once within 15 days. Inactive Areas are areas where soil-disturbing work activities have not occurred within 15 days. The SWPPP applies to all areas and item work of the project. A water pollution control schedule (WPCS) must be submitted with the SWPPP and must be updated regularly to ensure all areas, item work and associated temporary BMPs are adequately installed, maintained and documented. The Resident Engineer (RE) will conduct a review of the existing WPCS and active areas on a regular basis to determine if an inactive status should be applied to some DSAs.
2.1.5 Slope Length and Benches
Slope length is measured or calculated along the continuous inclined surface. Each discrete slope is between one of the following: top to toe, top to bench, bench to bench, and bench to toe.
Benches are drainage facilities that intercept surface flow, break up slope lengths and convey the resulting concentrated flow away from a slope. For the purpose of determining slope lengths, fiber rolls or other appropriate BMPs can be considered equivalent to a bench.
2.2 Temporary Soil Stabilization and Sediment Control
Implementation Guidance
Stormwater pollution control measures are required to be implemented on a year-round basis at an appropriate level. The requirements must be implemented in a proactive manner during all seasons while construction is ongoing. California has varied rainfall patterns throughout the state; therefore, the appropriate level of BMP implementation will also vary throughout the state.
The temporary soil stabilization and sediment control BMPs specified in this section are based on rainfall patterns (time frames, intensities, and amounts), general soil types, seasons, slope inclinations and slope lengths. Appropriate water pollution control includes the implementation of an effective combination of both soil stabilizing erosion and sediment control BMPs.
The following subsections describe both general principles and specific guidance for selecting and implementing temporary soil stabilization and sediment control BMPs. See Table 2-1 for a summary of the required temporary soil stabilization and sediment control BMPs.

a. BMP requirements of the CGP with associated Caltrans approved BMP options to meet the requirements. b. BMP numbers from the Caltrans Construction Site BMPs Manual. c. Required immediately for inactive DSAs which include all finished slopes and disturbed areas of construction not scheduled to be re-disturbed for at least 15 days.
d. Sediment controls and barriers include all temporary sediment control construction BMPs identified in the Storm Water Management Program (SWMP).
e. Required for active areas at least 24 hours prior to a forecasted storm event. f. Grade break BMPs are linear barriers that must be installed perpendicular to flow in accordance with the following: flat to 25 percent slopes maximum every 20-foot spacing, 25-50 percent slopes maximum every 15-foot spacing, and steeper than 50 percent slopes maximum every 10-foot spacing.
2.2.1 Scheduling
Construction scheduling shall consider the amount and duration of soil exposed to erosion by wind, rainfall, runoff, and vehicle tracking. Construction activities should be scheduled to minimize DSA during the time of the year when rainfall can be expected. A graphical WPCS shall be prepared that shows the sequencing of construction activities with the installation and maintenance of soil stabilization and sediment control BMPs. The WPCS should be updated routinely to ensure it reflects site conditions.
Water Pollution Control Program (WPCP) Preparation Manual Section 2 2-4
2.2.2 Preservation of Existing Vegetation
Preserving existing vegetation to the maximum extent possible and for as long as possible on a construction site reduces or eliminates erosion in those areas. To facilitate this practice, temporary fencing should be installed prior to commencement of clearing, grubbing or other soil-disturbing activities in areas where no construction activity is planned.
2.2.3 Stormwater Run-on and Concentrated Flows
The diversion of stormwater run-on and conveyance of concentrated flows must be considered in determining the appropriateness of the BMPs chosen. BMPs to divert or manage concentrated flows in a non-erodible fashion may be required on a project-by-project basis to divert off-site drainage through or around the construction site or to properly manage construction site stormwater runoff.
2.2.4 DSA Management
The DSA management guidelines are based on rainfall patterns (time frames, intensities, and amounts), general soil types, seasons, slope inclinations, and slope lengths. All of these factors must be considered in order to develop the appropriate levels of soil stabilizing and sediment control measures.
2.2.5 DSA Size Limitations
Limiting the amount of disturbed soil is a critical component in conducting an effective stormwater management program.
The Caltrans Standard Specifications place no limitations on the size of the project's total DSA.
The limitation on DSA has been removed because of the risk based approach taken by the CGP and the requirements for year round sediment and erosion control BMPs. The contractor can opt to utilize DSA size limitations as a BMP.
DSAs shall be protected as follows:
• Temporary control practices for inactive DSAs shall be implemented in accordance with Table 2-1 of this Manual and shown on the WPCS.
• Temporary control practices for active DSAs shall be implemented in accordance with Table 2-1 of this Manual.
For inactive DSAs, limit the erosive effects of stormwater flow on slopes by implementing BMPs such as fiber rolls to break up the slope lengths as follows:
1. Slope inclination 1:4 (Vertical versus Horizontal [V:H]) and flatter: BMPs shall be placed on slopes at intervals no greater than 20 feet.
a. Slope inclination between 1:4 (V:H) and 1:2 (V:H):
BMPs shall be placed on slopes at intervals no greater than 15 feet. b. Slope inclination 1:2 (V:H) or greater:
BMPs shall be placed on slopes at intervals no greater than 10 feet.
For-inactive DSAs, permanent erosion control shall be applied to areas deemed complete as soon as possible but may need to be delayed until the project's defined seeding window.
Provide construction site BMPs in addition to those specified in Table 2-1 to convey concentrated flows in a non-erodible fashion.
Water Pollution Control Program (WPCP) Preparation Manual Section 2 2-5
Do not use fiber rolls on slopes where soil conditions do not warrant (slopes prone to surface failure).
2.2.6 Soil Stockpiles
Temporary soil stockpiles shall be protected with temporary soil stabilization and/or sediment controls when required per Caltrans Standard Specifications and Standard Plans. Section 500 of the SWPPP or Section 30 of the WPCP lists various materials that can be used for soil stockpile management.
Caltrans specifications require Contractors to cover active and inactive soil stockpiles with soil stabilization material or a temporary cover and surround them with a linear sediment barrier.
2.2.7 Sediment/Desilting Basins
The nature of linear projects and constrained rights-of-way inherent to Caltrans work may prohibit the use of sediment/desilting basins at some locations on certain projects and on some projects altogether. Sediment basins shall, at minimum, be designed according to Caltrans requirements or the method provided in California Stormwater Quality Association’s (CASQA)’s Construction BMP Guidance Handbook. The required sediment/desilting basin shall be constructed in accordance with contract documents and in conjunction with other soil stabilization and sediment control measures.
2.3 Guidance for Implementation of Other BMPs
2.3.1 Mobile Operations
Mobile operations common to the construction of a project include asphalt recycling, concrete mixing, crushing and the storage of materials. BMPs shall be implemented as necessary, to control potential pollution that mobile operations may create.
The Caltrans Permit requires Caltrans to obtain coverage for any stormwater discharges associated with industrial activities under the Statewide Industrial General Permit for each batch plant and industrial facility, as defined in the Statewide Industrial General Permit. Please check with your District NPDES coordinator to determine specific regional requirements or exemptions.
The State Board website specifically addresses this issue noting that: “…if a contractor plans to operate: (1) a batch plant to manufacture Portland Cement Concrete, Hot Mixed Asphalt, or other material, or (2) a crushing plant to produce rock or aggregate, as part of a Caltrans project, either outside the job site or within the job site, that serves 1 or more contracts, the contractor must obtain coverage under the Industrial General Permit.”1
2.3.2 Wind Erosion Controls
Wind erosion controls shall be considered for all DSAs on the project site that are subject to wind erosion and when significant wind and dry conditions are anticipated during construction of the project. Refer to the Caltrans Standard Specifications for BMP line items for Wind Erosion Control BMPs, Caltrans Standard Specifications and for further reference see the Construction Site BMPs Manual.
1 State Water Resources Control Board, Frequently Asked Questions, Caltrans Construction, available at http://www.waterboards.ca.gov/water_issues/programs/stormwater/caltrans.shtml Water Pollution Control Program (WPCP) Preparation Manual Section 2 2-6
2.3.3 Tracking Controls
Tracking controls shall be implemented, as needed, to reduce the tracking of sediment and debris from the construction site. At a minimum, entrances and exits shall be inspected daily, and controls implemented as needed. Refer to the Caltrans Standard Specifications for BMP line items for Tracking Control BMPs (including Street Sweeping), Caltrans Standard Plans and for further reference see the Construction Site BMPs Manual.
2.3.4 Job Site Management (Non-Stormwater and Waste Management and Materials Pollution Controls)
The objective of the job site management (non-stormwater and waste management and materials pollution controls) is to reduce the discharge of materials other than stormwater to the stormwater drainage system or to receiving waters. These controls shall be implemented year round for all applicable activities, material usage, and site conditions. Refer to the Caltrans Standard Specifications and for further reference see the Construction Site BMPs Manual. 3-1
Preparing a Water Pollution
Control Program
3.1 Preparation and Approval of a WPCP
The Caltrans contract specifications require the contractor to prepare a Water Pollution Control Program (WPCP) for each project where the construction work results in less than 1 acre of soil disturbance or for small construction projects (1 to 5 acres of DSA) that have an approved Rainfall Erosivity Waiver authorized by the USEPA and therefore not subject to the requirements of the CGP or the LTCGP. The WPCP prepared for a project must comply with Caltrans Standard Specifications Section 13 Water Pollution Control and the contract special provisions following the procedures and format set forth in this Manual.
This section provides detailed, step-by-step procedures and instructions that contractors shall use to prepare a WPCP. This section also contains instructions for preparation of the WPCP Attachments and Appendices.
The contractor shall prepare and submit a complete WPCP to the Caltrans RE for review and acceptance. If revisions are required, as determined by the RE, the contractor must revise and resubmit the WPCP. The time frames for WPCP submittal, review, and re-submittal are specified in the contract special provisions or Caltrans Standard Specifications Section 13 Water Pollution Control. No activity having the potential to cause water pollution, as determined by the RE, shall be performed until the WPCP has been accepted by the RE. Construction activities that will not threaten water quality, such as traffic control, may proceed without an approved WPCP if authorized by the RE.
The WPCP template allows for the Alternate/Substitute WPCM and/or an Assistant WPCM to be included in case the primary designees are unavailable. The Alternate/Substitute WPCM must have the training and qualifications necessary to ensure the WPCP is in full compliance.
3.1.1 Information Provided by Caltrans
In addition to information in the contract special provisions and shown on the contract plans, Caltrans may supply to the contractor certain information developed during the design process.
The stormwater information necessary for the preparation of a project WPCP should be provided in the project Information Handout (IH) or should be requested from the project RE.
The contractor shall use this information to prepare the WPCP, as appropriate.
3.1.1.1 Vicinity Map
A map extending approximately one quarter mile (1,320 feet) beyond the property boundaries of the construction site showing: the construction site; surface water bodies (including known springs and wetlands); known wells; an outline of off-site drainage areas that discharge into the construction site; general topography; and the anticipated discharge location(s) where the construction site's stormwater discharges to a municipal storm drain system or other water body. A U.S. Geological Survey (USGS) quad map may be used for showing the project site Water Pollution Control Program (WPCP) Preparation Manual Section 3 3-2
and a one-quarter mile (1,320 feet) extension beyond the property boundaries of the construction site.
3.1.1.2 Soils/Geotechnical Report, Project Materials Report and/or Other Reports Toxic History of the Site: To the extent information is available from the soils/geotechnical report, the project materials report, site investigation report developed by the Hazardous Waste Section, or other regulatory or environmental compliance documentation (e.g. CEQA Initial Study, Phase I Environmental Site Assessment), the IH may include a description of all toxic materials known to have been treated, stored, disposed, spilled, or leaked in significant quantities onto the construction site.
Site Geotechnical Report: The IH may include a copy of the project materials report (geotechnical report). The contractor must describe the conditions of the fill and native soil materials that can be found at the construction site. Fill material should be described as whether it is native or non-native, contaminated or uncontaminated, and its stabilization technique (i.e., native soil coverage, asphalt or concrete coverage, landscape).
3.1.1.3 List of Pre-Construction (Existing) BMPs
The IH may provide a list and written descriptions of existing pre-construction practices, if any, that are already in place to reduce sediment and other pollutants in stormwater discharges.
These permanent BMPs may consist of biofiltration swales and strips, media filters, etc. Indicate whether there are existing pre-construction BMPs.
3.1.1.4 List of Permanent (Post-Construction) Stormwater Control Measures (BMPs) The IH may provide a written listing and narrative descriptions of post-construction permanent BMPs that have been included in the project. Narrative descriptions may also include operation and maintenance (O&M) procedures for the permanent BMPs, O&M short term and long term funding, and a statement indicating that the Maintenance Department will be responsible for O&M of the post construction BMPs.
3.1.1.5 Layout Sheets Showing Suggested Temporary BMP Locations The contract plan layouts sheets will show the location of anticipated construction site BMPs or the BMPs will be shown on contract plan quantity summary sheets. The contract plan layout sheets may show the location of anticipated contractor staging areas and other contractor support facilities.
3.1.1.6 Explanation of Construction Site (Temporary) BMPs The IH may provide a brief narrative explanation of the various temporary BMPs that may be implemented in the project, including any existing permanent BMPs that may be present within the project limits that can be used during construction, as well as any permanent BMPs that should be constructed early for use as a temporary BMP during construction, such as early application of permanent soil stabilization measures in areas that will no longer experience soil disturbance during construction.
3.1.1.7 Drainage Report
The IH may include a copy of the drainage report for the project or appropriate information, such as the hydrology maps, delineation of drainage boundaries, concentrations of runoff, and runoff coefficients.
Water Pollution Control Program (WPCP) Preparation Manual Section 3 3-3
3.1.1.8 Construction Site Estimates
The IH may contain portions of the Storm Water Data Report which includes for the project site an estimate of the:
• Construction site area in acres;
• Disturbed soil area in acres;
• Runoff coefficient of the construction site before and after construction; and • Percentage of the construction site impervious area (e.g., pavement, building) before and after construction.
3.1.1.9 Other Information
The IH may also include any other information that would explain the decisions or thought process behind the selection and deployment of the temporary BMPs chosen by the designer.
Examples include the designer’s proposed staging of the project and estimated time of year for those stages, and any specific BMP deployments that are considered to be critical to the success of the contractor’s WPCP.
3.1.1.10 Other Plans/Permits/Agreements
Other agencies may have issued permits/agreements or have plan requirements for the construction of the project or imposed certain conditions. If so, a written description of the permit/agreement conditions and a copy of the permit/agreement will be provided by Caltrans for inclusion in an attachment to the WPCP. Hazardous materials must be handled in accordance with specific laws and regulations and disposed of as a hazardous waste as outlines in Section 14 of the Standard Specifications. If during the preparation of the contract, it is known that special permits for accomplishing disposal of hazardous waste is known, then a written explanation will be provided to the contractor to be incorporated within this section and it must be consistent with other specifications in the contract. In addition, information regarding other related permits/agreements such as California Department of Fish and Wildlife or USACOE permits/agreements may also be included. For oversight projects, the Local Agency/Private Entity administering the project, is responsible for securing all necessary permits, certifications, and approvals. Copies of such documents shall be provided by the Local Agency/Private Entity and included as an attachment to the WPCP.
3.1.2 Minimum Requirements for Construction Sites
In order to ensure a minimum level of water pollution control, Caltrans has designated some BMPs as minimum requirements that contractors must implement during construction of highway projects statewide. The minimum required BMPs are specified in the contract standard specifications and contract special provisions. More information about minimum required BMPs can be found in the Caltrans Construction Site Best Management Practices (BMPs) Manual. 4-1

6.1.4 Highway Planting / Erosion Control Establishment Phase Highway planting including clearing and grubbing operations, soil preparation (grading, incorporation of soil amendments, placement of topsoil), irrigation (trenching, installation, trench backfilling), minor grading (top dressing, fine grading lawn and ground cover areas), hardscaping, planting (seeding and planting of plants), mulch (application of wood chips or other mulches) and plant establishment (weeding, plant replacement and if needed: fertilizer application, irrigation maintenance, reapplication of mulch). Erosion control includes placement of permanent erosion control materials and maintenance of temporary sediment controls during the erosion control establishment period.
The WPCDs for grading phase and highway construction phase may need to show different stages to completely identify all required BMPs. The stage construction sheets of the project plans may be used as base sheets for the WPCDs when staging is required.
The WPCDs provide field staff with the information on where to install BMPs so that they are effective. The WPCDs and WPCS provide the necessary tools for a contractor to plan and implement BMPs to meet the requirements of the project WPCP.
Prepare WPCDs in conformance with the following instructions and requirements. The WPCDs shall be no smaller than the “reduced plans” (approximately 11”x17”) issued by Caltrans. • The WPCDs shall show locations for the BMPs that will be used. • Include cover sheet(s) listing the BMPs that will be used along with the associated BMP symbols used on the WPCDs. Standard symbols and line types are shown in this Manual, Appendix B.
• Temporary WPC details not shown on applicable Standard Plans or contract plans must be shown in Attachment A.
• Additional BMP details may be necessary to describe site-specific BMP applications. BMP details other than the ones shown in the contract plans and Standard Plans shall be submitted to the RE for approval.
Use project layout, grading, stage construction, drainage sheets and/or erosion sheets as base sheets for the WPCDs. Use Section 30.1.2 as a guide to identify pollutant sources and BMPs for construction activities. Select BMPs that are appropriate for the site and show their locations on the WPCDs. The base sheets shall show the construction project in detail, including:
• The construction site perimeter
• Geographic features within or immediately adjacent to the site. Include surface waters such as lakes, streams, springs, wetlands, estuaries, ponds, and the ocean • Site topography before and after construction. Include roads, paved areas, buildings, slopes, drainage facilities, and areas of known or suspected contamination • Permanent (post-construction) BMPs. These are usually shown on the contract plans.
Delineate the following site information on the WPCDs:
• Discharge points from the project to site storm drain systems or receiving waters • Tributary areas and drainage patterns across the project area (show using flow arrows) into each onsite stormwater inlet or receiving water
• Tributary areas and drainage patterns to each onsite stormwater inlet, receiving water or discharge point
Water Pollution Control Program (WPCP) Preparation Manual Section 6 6-3
• Off-site tributary drainage areas that generate run-on to the project. (Where off-site tributary drainage areas are too large to depict on the drawings, use map notes or inserts illustrating the upstream drainage areas)

Active Areas. An area where soil disturbing activities have occurred at least once within 15 days.
Areas of Construction. All areas subject to land surface disturbance activities related to the project including, but not limited to, project staging areas, immediate access areas and storage areas.
Air Deposition. Airborne particulates from construction activities.
Beneficial Uses. As defined in the California Water Code, beneficial uses of the waters of the state that may be protected against quality degradation include, but are not limited to, domestic, municipal, agricultural and industrial supply; power generation; recreation; aesthetic enjoyment; navigation; and preservation and enhancement of fish, wildlife, and other aquatic resources or preserves.
Best Management Practices (BMPs). BMPs are scheduling of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the discharge of pollutants. BMPs also include treatment requirements, operating procedures, and practices to control site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.
Caltrans Permit. The Caltrans Statewide NPDES Permit for discharges from Caltrans properties, facilities, and activities (Order No. 2012-011-DWQ, NPDES No. CAS000003), issues by the SWRCB.
Chain of Custody (COC). Form used to track sample handling as samples progress from sample collection to the analytical laboratory. The COC is then used to track the resulting analytical data from the laboratory to the client. COC forms can be obtained from an analytical laboratory upon request.
Coagulation. The clumping of particles in a discharge to settle out impurities, often induced by chemicals such as lime, alum, and iron salts.
Common Plan of Development. Generally, a contiguous area where multiple, distinct construction activities may be taking place at different times under one plan. A plan is generally defined as any piece of documentation or physical demarcation that indicates that construction activities may occur on a common plot. Such documentation could consist of a tract map, parcel map, demolition plans, grading plans or contract documents. Any of these documents could delineate the boundaries of a common plan area. However, broad planning documents, such as land use master plans, conceptual master plans, or broad-based CEQA or NEPA documents that identify potential projects for an agency or facility are not considered common plans of development.
Construction Activity. Includes clearing, grading, or excavation and contractor activities that result in soil disturbance.
Construction Site. The area involved in a construction project as a whole.
Construction Site BMPs. Temporary control practices (BMPs) that are required only temporarily to address a short-term stormwater contamination threat. For example, silt fences are located near the base of newly graded slopes that have substantial area of exposed soil. Then, during rainfall, the silt fences allow capture sediment from erosion of the slopes.
Contamination. An impairment of the quality of the waters of the state by waste to a degree that creates a hazard to the public health through poisoning or through the spread of disease including any equivalent effect resulting from the disposal of waste, whether or not waters of the state are affected.
Contractor. Party responsible for carrying out the contract per plans and specifications. The Standard Specifications and contract special provisions contain stormwater protection requirements the contractor must address.
