5 Section 1 SWPPP Requirements 1.1 Introduction King Park is located in north central San Mateo and covers approximately 6.2 acres in total. The park is bounded by East Santa Inez Avenue to the north, North Fremont Street to the east, Monte Diablo Avenue to the south and North El Dorado Street to the west. The property is owned and operated by the. The park includes a community center, parking lot, lighted natural grass field, children s playgrounds, basketball court, pathways, and other supporting amenities. The construction activities planned for this project will disturb approximately 3.5 acres of the 6.2-acre site. The proposed project will convert the natural grass field to synthetic turf, replace chain link fencing at the perimeter of the field, supplement existing site furnishings, re-locate a park pathway, modify site lighting, and renovate landscape areas. The project s location is shown on the Vicinity Map below. This project has been classified as a Risk Level 2 project. Information to support the project s risk level is attached in Appendix J. 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) Order No DWQ as amended by Order No DWQ (NPDES No. CAS000002) issued by the State Water Resources Control Board.

7 This SWPPP has been prepared to comply with the California s General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities (General Permit) Order No DWQ as amended by Order No DWQ (NPDES No. CAS000002) issued by the State Water Resources Control Board (SWRCB). A copy of the General Permit can be found in Appendix A. 1.1 SWPPP Objectives: The discharger shall ensure that the SWPPPs for all traditional project sites are developed and amended or revised by a QSD. The SWPPP is designed to address the following objectives: 1. All pollutants and their sources, including sources of sediment associated with construction, construction site erosion and all other activities associated with construction activity are controlled; 2. Where not otherwise required to be under a Regional Water Quality Control Board (RWQCB) permit, all non-storm water discharges are identified and either eliminated, controlled, or treated; 3. Site BMPs are effective and result in the reduction or elimination of pollutants in storm water discharges and authorized non-storm water discharges from construction activity to the Best Available Technology/Best Control Technology (BAT/BCT) standard; 4. Calculations and design details as well as BMP controls for site run-on are complete and correct, and 5. Identify stabilization BMPs to be installed to reduce or eliminate pollutants after construction. 6. Identify post-construction BMPs, which are those measures to be installed during construction that are intended to reduce or eliminate pollutants after construction is completed (post-construction BMPs are required for all sites by Section XIII.B of the General Permit). Note that post-construction BMPs should be developed early in the project planning/design process and reports or drawings related to permanent BMP design should be referenced as needed. 7. Identify and provide methods to implement BMP inspection, visual monitoring, Rain Event Action Plan (REAP) and Construction Site Monitoring Program (CSMP) requirements to comply with the General Permit.

11 1.5 Retention Records The General Permit (Section I.J.69 and IV.G) requires that all dischargers maintain a paper or electronic copy of all required records for three years from the date generated or date submitted, whichever is last. These records must be available at the construction site until construction is completed. The discharger shall furnish the RWQCB, SWRCB, or US Environmental Protection Agency (EPA), within a reasonable time, any requested information to determine compliance with this General Permit. The documents will be kept on site in the construction trailer for the duration of construction and uploaded to the SMARTS system. 1.6 Required Non-Compliance Reporting If a discharge occurs or if the project receives a written notice of non-compliance, the QSP shall immediately notify the LRP. The LRP will file a violation report to the Regional Water Board within 30 days of identification of non-compliance using SMARTS. Corrective measures will be implemented immediately following the discharge, notice or order. Exceedances and violations should be reported using the SMARTS system and include the following: Numeric Action Level (NAL) exceedances (NAL Exceedance Report upon request of the RWQCB); Numeric Effluent Limitation (NEL) Violation Report; Self- reporting of any other discharge violations or to comply with RWQCB enforcement actions; and Discharges which contain a hazardous substance in excess of reportable quantities established in 40 CRF and 302.4, unless a separate NPDES Permit has been issued to regulate those discharges. Documentation of all reportable exceedances shall be included in this SWPPP. The results of an NAL exceedance site evaluation along with other non-compliance events will be included in Appendix D. Reporting requirements for Numeric Action Levels (NALs) exceedances are discussed in Section 7.8. Section _SWPPP.doc Page 1-7

To change the acreage covered, the permittee must electronically file modifications to PRDs (revised NOI, site map, SWPPP revisions as appropriate, and certification that new landowners have been notified of applicable requirements to obtain permit coverage (including name, address, phone number, an address of new landowner) in accordance with requirements of the General Permit within 30 days of a reduction or increase in total disturbed area. Include any updates to PRDs submitted via SMARTS in SWPPP Appendix E. Document any related SWPPP revisions/amendments (Section II.C.2) in SWPPP Appendix C. 1.9 Notice of Termination To terminate coverage under the General Permit, a Notice of Termination (NOT) must be submitted electronically by the LRP via SMARTS. A final site map and photos are required to be submitted with the NOT. Filing a NOT certifies that all General Permit requirements have been met. The NOT is submitted when the construction project is complete and within 90 days of meeting all General Permit requirements for termination and final stabilization (Section II.D) including: Section _SWPPP.doc Page 1-8

13 The site will not pose any additional sediment discharge risk than it did prior to construction activity. All construction related equipment, materials and any temporary BMPs no longer needed are removed from the site. Post-construction stormwater management measures are installed and a long-term maintenance plan that is designed for a minimum of five years has been developed. The NOT must demonstrate through photos, Revised Universal Soil Loss Equation (RUSLE) results, or results of testing and analysis that the project meets all of the requirements of Section II.D.1 of the General Permit by one of the following methods: 70% final cover method (no computational proof required); or RUSLE/RUSLE2 method (computational proof required); or Custom method (discharge demonstrates that site complies with final stabilization).

14 Section 2 Project Information 2.1 Introduction and Site Description Existing Conditions For Site Map, see Exhibit 1.1 in Section 1.1. The existing site is located within a developed area of San Mateo and is currently used as a community park. This use will not change as a result of this project. The large grass field is surrounded by mature street trees on three sides and open park space to the south. Project has Fill Material: Yes No Project has Native Material: Yes No Unique Features Onsite: Water Bodies Wetlands Endangered or Protected Species Environmentally Sensitive Areas Other None Drainage In general, stormwater sheet flows to the north and east towards San Francisco Bay. The northeast corner of the park is the lowest point. There are no off-site piped storm drains in the streets adjacent to the park. Stormwater is conveyed into curb inlets via gutters in the street. The inlets fill with water and bubble up and convey excess water to the next downstream inlet, and so on. Water Quality Impairments The project site is located within the Pump Stations sub-watershed within the San Mateo Creek watershed. San Mateo Creek discharges into San Francisco Bay. Per the State s published 303d list of water quality impairments, San Mateo Creek is currently impaired for Toxicity, diazinon and trash. San Mateo Creek watershed is listed as COLD, SPAWN and MIGRATORY under existing and proposed beneficial uses. Geology and Groundwater The site geology consists primarily of sandy silt, dark brown silty clay and mottled brown and tan clay to the extent of each of the borings. Groundwater was not encountered in any of the borings at the time conducted. Laboratory testing indicated that the soils are highly plastic and thus expansive. Percolation rates were measured and ranged between 0.25 and 1.0 inches per hour. More detailed soil information can be found in the report titled Geotechnical Investigation for Proposed Turf Field MLK Field 725 Monte Diablo Avenue, San Mateo, California prepared by GeoForensics Inc., dated January 19, Section _SWPPP.doc Page 2-1

15 Proposed Improvements The proposed project will convert the field from natural grass to synthetic turf and renovate surrounding park areas. The other park improvements include new pathways, resurfaced basketball court, picnic area, lighting, fencing and landscape. Section _SWPPP.doc Page 2-2

There is no storm water run-on coming from offsite areas. See Appendix O for site exhibits. Section _SWPPP.doc Page 2-3

17 2.3 Findings of the Construction Site Sediment and Receiving Water Risk Determination The project s overall Sediment Risk is Low. Runoff from the project site eventually discharges into San Mateo Creek which discharges into San Francisco Bay. The overall Receiving Water Risk is High. Therefore, the project has been identified as a Risk Level 2. The SWPPP must comply with requirements spelled out in Risk 2 determination. See Appendix B for completed Risk determination worksheet and Appendix J for Risk 2 requirements. 2.4 Construction Schedule The construction schedule shall identify specific phases of construction activities that can result in different water quality effects from different water quality pollutants. Grading and Land Development Phase Vertical Construction Phase Final Landscaping and Site Stabilization Phase The Site sediment risk was determined based on the construction taking place between March 7, 2019 and August 21, Modifications or extension of the schedule (start and end dates) may affect the 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 project construction schedule will be supplied by the Contractor and located in Appendix F. 2.5 Potential Construction Site Pollutant Sources The following is a list of construction materials that will be used and activities that will be performed that will have the potential to contribute pollutants, other than sediment, to stormwater runoff [control practices for each activity are identified in the Erosion Control Plans (Appendix O), see Appendix G and/or in Section 3.2 through 3.3 for the BMPs.

Section _SWPPP.doc Page 3-4

24 Section 4 BMP Inspection, Maintenance, and Rain Event Action Plans 4.1 BMP Inspection and Maintenance Inspections will be conducted as follows: Prior to a forecast storm After a rain event that causes runoff from the construction site At 24-hour intervals during extended rain events At any other time(s) or intervals of time specified in the contract documents Blank inspection checklists can be found in Appendix I. Contractor to fill out construction checklists as required. The General Permit requires (Attachments C, D, E: Section G.5) that completed inspection checklists be maintained with the on-site SWPPP. In general the information required to be recorded for BMP/facility inspections includes: the date of the inspection, weather information, site information, observations, descriptions of the inspected BMPs and any deficiencies, and the corrective actions that were taken such as BMPs that were fixed or additional BMPs that were implemented, and the inspectors name, title, and signature. The required frequency of BMP inspections depends on the type of BMP that is implemented. The General Permit (Attachments C, D, E; Section G.2) requires routine weekly inspections and daily inspections during rain events of all BMPs (for all Risk Categories); however, some BMPs (e.g. tracking controls; Attachments D & E, Section E.7) may require daily monitoring. BMPs must be maintained regularly based on permitrequired inspections and observations during the course of normal construction activities. The General Permit requires dischargers to begin implementing corrective actions within 72 hours for deficiencies identified during inspections (Attachments C, D, E; Section G.3). SWPPP amendments should be prepared by the QSD if warranted by the problem encountered and corrective action required. 4.2 Rain Event Action Plans (REAPs) This project is a Risk Level 2, therefore is required to do REAPs. The REAP is a written document designed to be used as a planning tool by the QSP to protect exposed portions of the project site and to ensure that the discharger has adequate materials, staff and time to implement erosion and sediment control measures. These measures are intended to reduce the amount of sediment and other pollutants that could be Section _SWPPP.doc Page 4-1

25 generated during the rain event. It is the responsibility of the QSP to be aware of precipitation forecast and to obtain and print copies of forecasted precipitation from NOAA s National Weather Service Forecast Office. See Appendix Q for REAPs template. The QSP will need to customize the templates for each rain event. The QSP shall maintain a paper copy of the completed REAPs in compliance with the record retention requirements of the SWPPP.Completed REAPs shall be located in Appendix Q as well. The QSP will develop a event specific REAP 48 hours in advance of a precipitation event forecast to have 50% or greater chance of producing precipitation in the project area. The REAP will be onsite and be implemented 24 hours in advance of any predicted precipitation event. Section _SWPPP.doc Page 4-2

26 Section 5 Training The General Permit requires (Section VII) that all elements of the SWPPP be developed by a QSD and implemented by a QSP. The QSP may delegate tasks to trained employees provided adequate supervision and oversight is provided. Personnel at the site shall receive training appropriate for individual roles and responsibilities on the project. Appropriate personnel shall receive training on SWPPP implementation, BMP inspection and maintenance, and record keeping. Document all training activities (formal and informal) and retain a record of training activities in SWPPP Appendix K. Training documentation must also be submitted in the Annual Report.

30 Section 7 Construction Site Monitoring Program 7.1 Purpose The General Permit (Attachments C, D, E; Section I.1.a) requires that a written site specific Construction Site Monitoring Program (CSMP) be developed by each discharger prior to the commencement of construction activities, and be revised as necessary to reflect project revisions and that the CSMP be included with the SWPPP. This CSMP was developed to address the following objectives: 1. To demonstrate that the site is in compliance with the Discharge Prohibitions NALs of the Construction General Permit. 2. To determine whether non-visible pollutants are present at the construction site and are causing or contributing to exceedances of water quality objectives; 3. To determine whether immediate corrective actions, additional Best Management Practices (BMP) implementation, or SWPPP revisions are necessary to reduce pollutants in stormwater discharges and authorized non-stormwater discharges; 4. To determine whether BMPs included in the SWPPP and REAP are effective in preventing or reducing pollutants in stormwater discharges and authorized nonstormwater discharges. 7.2 Applicability of Permit Requirements The Construction Site Monitoring Program (CSMP) has been developed for this site to help demonstrate that the site is in compliance with the specific requirements and objectives identified in the General Permit. The CSMP will describe the monitoring requirements for stormwater and non-stormwater visual observations; stormwater and non-stormwater sample collection; and receiving water monitoring. The CSMP will identify the applicable monitoring requirements; inspection and observation; and sampling frequency based on this project s Risk Level 1 designation. Implementation of this CSMP will help the contractor in determining the appropriate BMP s to reduce visible and non-visible pollutants present at the site. This project has been determined to be a Risk Level 2 project. The General Permit identifies the following types of monitoring as being applicable for a Risk Level 2 project. Risk Level 2 Visual inspections of Best Management Practices (BMPs); Visual monitoring of the site related to qualifying storm events; Visual monitoring of the site for non-stormwater discharges; Sampling and analysis of construction site runoff for ph and turbidity; Sampling and analysis of construction site runoff for non-visible pollutants when applicable; and Sampling and analysis of non-stormwater discharges when applicable.

31 Visual Inspections Sampling & Analysis Storm Water Pollution Prevention Plan (SWPPP) 7.3 Monitoring Visual monitoring of the site shall be performed before, during and after all qualifying rain events to ensure BMP s are functioning properly. Measures shall also be checked weekly during periods of heavy usage, and monthly during periods of normal usage. All erosion and sediment control measures shall be maintained until disturbed areas are stabilized. Problem areas shall be documented, measures identified and implemented. Table 7.3 a below summarizes the monitoring requirements for this Risk Level 2 site. Risk Level 2: Visual monitoring, inspections, and sampling requirements of the General Permit are triggered by a qualifying rain event. The General Permit defines a qualifying rain event as any event that produces ½ inch of precipitation. A minimum of 48 hours of dry weather will be used to distinguish between separate qualifying storm events. Table 7.3a Summary of Risk Level 2 Monitoring Requirements Type of Monitoring When Within first two hours of discharge from site. Non-visible pollutants; spill/bmp failure based on pollutant source assessment Collect samples of runoff affected by the spilled or released material(s) and runoff that is unaffected by the spilled or released materials(s). Particle Size Effluent sampling: Turbidity Effluent sampling: ph Contained rain water. Non- stormwater Other When sediment basins are used. If needed to justify site specific sediment risk using the Revised Universal Soil Loss Equation (RUSLE). Collect a minimum of three samples per day. Collect runoff samples representative of site discharges. During construction phases with high risk of ph discharge. Collect a minimum of three samples per day. Collect runoff samples representative of site discharges. At time of discharge. At locations where discharged off the site. RWQCB or Total Maximum Daily Loads (TMDLs) may require other monitoring. Non-stormwater inspection Quarterly for each drainage area. Qualifying rain event: Post-rain inspection All discharge locations within two business days after each qualifying rain event. Visually observe discharge of contained stormwater when discharged. Section _SWPPP.doc Page 7-2

32 Qualifying rain event: Pre-rain inspection During rain inspection BMP All drainage areas, BMPs, and stormwater containments within two business days of each qualifying rain event. See BMP inspection below. Weekly and every 24 hours during extended storm events. A. BMP Inspections The General Permit requires that BMPs be inspected weekly and once each 24-hour period during extended storm events. The purpose of these inspections is to identify BMPs that: Need maintenance to operate effectively; Failed; or Could fail to operate as intended. If deficiencies are identified during BMP inspections, repairs or design changes to BMPs must be initiated within 72 hours of identification and need to be completed as soon as possible. All BMP inspections must be documented on an inspection checklist. See Stormwater Quality Construction Site Inspection Checklist in Appendix N. Include photographs taken during inspection if necessary. B. Qualifying Rain Event Inspections The General Permit requires that the construction site be inspected within two days prior to a predicted Qualifying Rain Event is and within two days after a Qualifying Rain Event. These inspections are only required during normal business hours of the construction site. A Qualifying Rain Event is defined in the General Permit as one that produces ½ -inch or more of precipitation with a 48 hour or greater period between rain events. The General Permit requires that dischargers only use weather forecasts from the National Oceanographic and Atmospheric Administration (NOAA). Pre-project inspections should be initiated after consulting NOAA for a qualifying rain event with 50% or greater probability of precipitation (PoP). These forecasts can be obtained at Records must be kept of all qualifying rain event inspections. Records need to be maintained on site and document: Personnel performing the observations; Observation dates (time and date); Section _SWPPP.doc Page 7-3

33 Weather conditions (including the rain gauge reading for the qualifying rain event); Locations observed; and Corrective actions taken in response to observations. See Storm Water Quality Construction Site Inspection Checklist in Appendix N for all rain event, pre-rain event and post-rain event inspections. 1. Pre-rain Event Inspection The purpose of the pre-rain event inspection is to make sure the site and the BMPs are ready for the predicted rain. Consistent with guidance from the State Water Resources Control Board, pre-rain BMP inspections and visual monitoring will be triggered by a NOAA forecast that indicates a probability of precipitation of 50% or more in the project area. Within 48-hours prior to a qualifying event a stormwater visual monitoring site inspection needs to cover: All stormwater drainage areas to identify any spills, leaks, or uncontrolled pollutant sources; All BMPs to identify whether they have been properly implemented per the SWPPP and/or REAP; Stormwater storage and containment areas to detect leaks and ensure maintenance of adequate freeboard; and The presence or absence of floating and suspended materials, a sheen on the surface, discolorations, turbidity, odors, and source(s) of any observed pollutants within stored stormwater. 2. Extended Rain Event Inspection During an extended rain event BMP inspections will be conducted to identify and record: BMPs that are properly installed; BMPs that need maintenance to operate effectively; BMPs that have failed; or BMPs that could fail to operate as intended. If the construction site is not accessible during the rain event, the visual inspections shall be performed at all relevant outfalls, discharge points, downstream locations. The inspections should record any projected maintenance activities. 3. Post-Rain Event Inspection The purpose of the post-rain event inspection is to observe the discharge locations and the discharge of any stored or contained rainwater; determine if BMPs functioned as designed; and indentify if any additional BMPs are required. Within 48 hours following a qualifying rain event (0.5 inches of rain) a stormwater visual Section _SWPPP.doc Page 7-4

34 monitoring site inspection needs to cover: All stormwater discharge locations; Storm Water Pollution Prevention Plan (SWPPP) The discharge of stored or contained stormwater that is derived from and discharged subsequent to a qualifying rain event; and All BMPs to determine if they were adequately designed, implemented, and effective. After assessing BMPs it should be noted on the inspection form whether the BMPs need maintenance. C. Visual Monitoring Procedures Visual monitoring shall be conducted by the QSP or staff trained by and under the supervision of the QSP. The name(s) and contact number(s) of the site visual monitoring personnel are listed below and their training qualifications are provided in Appendix L. Assigned inspector: Contact phone: Alternate inspector: Contact phone: Stormwater observations shall be documented on the Visual Inspection Field Log Sheet, See Appendix N. D. Non-stormwater Discharges Inspections The General Permit requires that construction sites, regardless of risk level, be inspected quarterly for the presence of non-stormwater discharges. Records must be kept of all inspections and must be maintained on site. Non-stormwater discharge inspections are only required during normal business hours of the construction site. The purpose of these inspections is to detect unauthorized nonstormwater discharges and observe authorized non-stormwater discharges. Quarterly inspections need to include each drainage area of the project and document: Presence of indications of unauthorized and authorized non-stormwater discharges and their sources; Pollutant characteristics of the non-stormwater discharge (floating and suspended material, sheen, discoloration, turbidity, odor, etc.) Personnel performing the observations; Dates and approximate time each drainage area and non-stormwater discharge was observed; and Response taken to observations. Section _SWPPP.doc Page 7-5

35 E. Active Treatment Systems Monitoring This project does not require a project specific Sampling and Analysis Plan for an ATS because deployment of an ATS is not planned. F. Bioassessment Monitoring This project is not subject to bioassessment monitoring because it is not a Risk Level 3 project. 7.4 Water Quality Sampling and Analysis Procedures Water quality sampling and analysis is required for all Risk Level 2 and 3 projects. Typically, Risk Level 1 projects are not required to conduct water quality sampling and analysis unless there is a risk of non-visible pollutant discharge. See Sampling Activity Log in Attachment N. The purpose of sampling is to determine whether BMPs implemented on a construction site are effective in controlling potential construction site pollutants, which come in contact with stormwater or non-stormwater, and to demonstrate compliance with the applicable NALs or NELs. This section discusses the procedures and the information that need to be included in the CSMP for water quality sampling and analysis. This section is divided into the following: Potential pollutant sources; Monitoring constituents by risk level; Sampling locations; Sample collection and handling; and Analytical methods, laboratories, and field meters. A. Potential Pollutant Sources 1. Sediment and Turbidity Conditions or areas at a construction site that may cause sediment, silt, and /or turbidity in site runoff include: Exposed soil areas with inadequate erosion control measures; Areas of active grading; Poorly stabilized slopes; Section _SWPPP.doc Page 7-6

36 Lack of perimeter sediment controls; Areas of concentrated flow on unprotected soils; Poorly maintained erosion and sediment control measures; Tracking sediment onto roads and paved surfaces; Unprotected soil stockpiles; and Failure of an erosion or sediment control measure. 2. High ph Storm Water Pollution Prevention Plan (SWPPP) Conditions or areas at a construction site that may cause high ph in site discharges include: Concrete pours and curing; Concrete waste management areas; Soil amendments (e.g. fly ash and lime); and Mortar and stucco mixing, application, and waste management areas. 3. Non-Visible Pollutants Monitoring for pollutants not visually detectable is only required if those pollutants are determined to be potentially present in stormwater leaving the construction site; and is typically the result of a BMP failure or spill on the construction site. This determination is documented in the pollutant source assessment in the SWPPP. Projects should attempt to eliminate the exposure of construction materials to prevent stormwater pollution and limit sampling and analysis requirements. It is important to note that covered construction materials or those that are in their final constructed form, do not need to be monitored. Materials that are stored exposed to precipitation and may generate runoff need to be considered for non-visible pollutant monitoring. Non-visible pollutants may also exist on the project site as a result of the land use prior to the start of the construction activity. To determine the potential of pollutants to exist on the construction site as a result of past land use activities, dischargers should review existing environmental and real estate documentation. Good sources of information on previously existing contamination and past land uses include, but are not limited to the following: Initial Studies or Environmental Impact Reports (EIRs) prepared under the requirements of the California Environmental Quality Act (CEQA); Environmental Assessments or Environmental Impact Statements (EIS) Section _SWPPP.doc Page 7-7

37 prepared under the requirements of the Nation Environmental Policy Act (NEPA); and Phase I Assessments prepared for property transfers. Non-visible pollutants in site discharges may result from materials that: Are being used in construction activities; Are stored on the construction site; Were spilled during construction operations and not cleaned up; Were store (or used) in a manner that presented the potential for a release of the material during past land use activities; Were spilled during previous land use activities and not cleaned up; or Were applied to soil as part of past land use activities. B. Monitoring Constituents Risk Level 2 At a minimum, risk Level 2 projects are required to collect water quality samples for ph (during construction phases with a high risk of high ph discharge) and turbidity (all phases). Additional monitoring may be required by the RWQCB. Risk Level 2 projects are required to collect water quality samples if there is a BMP breach, malfunction, leakage, or spill. Water quality samples should be taken for non-visible pollutants that may have been discharged from the site as identified in the site pollutant source assessment. Particle size analysis may be needed if a Risk Level 2 project is using a sediment basin or if needed to justify a site specific risk level calculation using RUSLE. The particle size analysis provides the information needed to determine the K-factor. C. Sampling Locations 1. Stormwater Runoff Risk Level 2 and 3 projects are required to collect water quality samples of runoff that is discharged off-site. Samples must be representative of the runoff associated with construction activity from the entire project disturbed area. Samples locations representative of runoff in each drainage area should be considered to ensure adequate representation of the flow and characteristics of the site s discharges. 2. Non-Stormwater Runoff Risk Level 2 and 3 projects are also required to collect water quality samples to Section _SWPPP.doc Page 7-8

38 characterize authorized and unauthorized non-stormwater discharged from the site. 3. Receiving Water The project does not have a direct discharge to any receiving waters, therefore receiving water monitoring is not required. 4. Non-Visible Pollutant Monitoring In situations where a breach, malfunction, leakage, or spill has occurred, dischargers must collect a sample of runoff that has come into contact with the no come in contact with the materials and must also collect a runoff sample that has not come into contact materials (uncontaminated sample ) for comparison. D. Sample Collection and Handling It is important to use the correct methods to collect and handle samples to ensure the samples are valid. While the handling requirements apply primarily to grab samples collected for laboratory analysis, filed measurements can be affected by sample collection procedures. The General Permit requires dischargers to designate and train personnel to collect, maintain, and ship water quality samples in accordance with the Surface Water Ambient Monitoring Program (SWAMP) 2008 Quality Assurance Program Plan (QAPrP), which is available at Sampling methods, handling procedures, and locations should be identified in advance of the sampling event in order to provide sufficient time to gather the supplies and equipment necessary to sample and plan for safe access by the sampling crew(s). Adherence to SWAMP sampling guidance and proper development of a sampling plan provides for consistent, reproducible, and accurate results. For some constituents, especially trace metals, trace organics, and organic carbon, sampling protocols are very important as contamination of samples due to incorrect sampling protocols is possible. Design of the field sampling procedures should carefully consider contamination potential from sample location (e.g., sediment disturbances, equipment exhaust), sampling techniques, and sample handling. Field crews should be trained in the appropriate site specific methods specified in the sampling plan. Clean sampling based on the US Environmental Protection Agency (EPA) Method 1669 should be used when sufficiently low detection concentrations are expected for at least trace metals and mercury. However, it is recommended that all sampling plans incorporate a clean technique approach including the following protocols: Samples (for laboratory analysis) are collected only in analytical laboratory-provided sample containers; Clean, powder-free nitrile gloves should be worn for collection of samples; Glove are changed whenever something not known to be clean has been touched; Section _SWPPP.doc Page 7-9

39 Decontaminate all equipment (e.g. bucket, tubing) except laboratory provided sample containers, prior to sample collection using a trisodium phosphate (TSP)- soapy water wash, distilled water rinse, and final rinse with distilled water. (Dispose of wash and rinse water appropriately, i.e., do not discharge to storm drain or receiving water); and To reduce potential contamination, sample collecting personnel must adhere to the following rules while collecting samples: o o o o o No Smoking; Never sample near a running vehicle; Do not park vehicles in the immediate sample collection are (even non-running vehicles); Do not eat or drink during sample collection; and Do not breathe, sneeze, or cough in the direction of an open sample container. The most important aspect of grab sampling is to make sure that the sample best represents the entire runoff stream. Water quality samples should be collected in appropriate sample containers and be of adequate volume to conduct the required measurements or laboratory analyses. Typically, samples are collected by dipping the collection container in the runoff flow paths and streams as noted below. Note, however that depending upon the specific test that is required, some bottles may contain preservatives. These bottles should never be dipped in the stream, but filled indirectly from the collection container. i. For small streams and flow paths, simply dip the bottle facing upstream until full. ii. iii. iv. For larger stream that can be safely accessed, collect and sample in the middle of the flow stream by directly dipping the mouth of the bottle. Once again making sure that the opening of the bottle is facing upstream as to avoid any contamination by the sampler. For larger streams that cannot be safely waded, pole-samplers may be needed to safely access the representative flow. Avoid collecting samples from ponded, sluggish or stagnant water. v. Avoid collecting samples directly downstream from a bridge as the samples can be affected by the bridge structure or runoff from road surface. All sampling and sample preservation must be in accordance with the current edition of Standard Methods for the Examination of Water and Wastewater (American Public Health Association). Section _SWPPP.doc Page 7-10

40 All samples must be maintained between 0-6 degrees Celsius during delivery to the laboratory. Samples must be kept on ice, or refrigerated, from sample collection through delivery to the laboratory. Shipped samples should be place inside coolers with ice. Make sure the sample bottles are well packaged to prevent breakage and secure cooler lids with packaging tape. Ship samples that will be laboratory analyzed to the analytical laboratory right away. Many analytical methods have short hold-times before which the analysis must be started. Hold times are measured from the time the sample is collected to the time the sample is analyzed. The General Permit requires that samples be received by the analytical laboratory within 48 hours of the physical sampling (unless otherwise required by the analytical laboratory). Most sites will require the use of some sort of field meter to measure turbidity and ph. Some field meters can be placed directly in the flow of water and gather instantaneous data. Meters with probes that can be directly placed into the flow are ideal, however low flow conditions may not allow for this type of measurement. In this case, grab samples can be collected and placed within the field meter s recording container. Section 7.0 of this guidance document provided step-by-step instruction using an example field meter. All monitoring instruments and equipment (including a discharger s own field instruments for measuring ph and turbidity) should be calibrated and maintained in accordance with manufacturers specifications to ensure accurate measurements. Many manufacturers provide step-by-step instructions for the use and calibration of their meters and these instructions should be followed. If using field meters, ph and turbidity measurements should be conducted immediately (i.e. samples should not be stored for later measurements). Collect proper information regarding time and sampling conditions, appropriately label the bottles, and fill out the required chain of custody forms and field logs. E. Analytical Methods, Laboratories, and Field Meters All laboratory analyses must be conducted according to analytical procedures specified in 40 Code of Federal Regulations (CFR) Part 136, unless other analytical procedures have been specified in the General Permit or by the RWQCB. With the exception of field analyses conducted by the discharger for turbidity and ph, all analyses must be sent to and conducted by a state-certified analytical laboratory. Currently, the SSC method is not state certified and a limited number of laboratories have the capability of doing this analysis. Analytical laboratories should be contacted and a contract should be worked out before the wet season to minimize potential disruptions during the critical sampling period. A laboratory should be chosen foremost by their accreditation, ability to perform the required samples in the desired turn-around-time, and then by their proximity for ease of sample Section _SWPPP.doc Page 7-11

41 delivery. Although with overnight mail delivery, proximity is less important, it may still be an important factor to avoid bottle breakage during shipment. State-certified analytical laboratories can be found by using the Environmental Laboratory Accreditation Program s (ELAP) website at: The analytical method/protocol, minimum detection limits, and reporting units for the water quality constituents specifically indentified in the General Permit are presented in Table 7.4- A. Table 7.4-A Parameter Water Quality Constituent Analytical Method/Protocol, Minimum Detection Limits, Sample Size and container Requirements. Test Method/Protocol Minimum Detection Limit Minimum Sample Volume Container Type ph Field meter or ph test kit 0.2 ph Units NA Plastic Turbidity Field meter or EPA NTU 500 ml Plastic SSC ASTM Method D mg/l 200 ml Contact Lab Non-visible pollutants may include a wide range of analytical methods. A list of potential non-visible pollutants based on common construction activities is shown in Table 7.4-B. This list is not meant to be inclusive but to provide general guidance for projects. Consult with the analytical laboratory or 40 CFR Part 136 to identify specific analytical methods, sample volume, and containers needed for the expected non-visible pollutants. Dischargers can perform ph analysis on site with a calibrated ph meter, or ph test kit. Dischargers can perform turbidity analysis using a calibrated turbidity meter (turbidimeter), either on site or at an accredited analytical laboratory. Many manufacturers offer single parameter meters of multiple parameter meters with various optional probes. Dischargers will need to determine the best type of meter for their individual situation. Any meter selected for field monitoring should have the ability to be calibrated, be accompanied by detailed operation instructions, and should be ruggedly designed for filed use and long term storage (you are unlikely to need it during the dry season).

Multi-parameter meters are more costly, but provide increased versatility, have user friendly interfaces, and can provide instantaneous readings of multiple parameters. Probes for the multi-parameter meters can be attached to cables of varying lengths that make it possible to sample at a great distance from the runoff flow. Hach, Hydrolab, Global Water, Fisher Scientific, and LaMott are some known manufacturer and/or vendors of turbidity and ph meters. Whichever turbidimeter is selected, it is important to use the same meter; different meters may have different results even if properly calibrated. If you need to use several turbidimeters, then assign to each meter to a specific location. Section _SWPPP.doc Page 7-13

43 Dischargers utilizing a sediment basis are required to conduct a soil particle analysis. Dischargers may also want to conduct this analysis to establish site-specific particle size information, which can be used to justify the project risk level using RUSLE. (The particle size analysis provides the K factor.) The soil particle analysis is conducted using the American Society for Testing and Materials (ASTM) test method ASTM D-422 (Standard Test Method for Particle-Size analysis of Soils), as revised, to determine the percentages of sand, very fine sand, silt, and clay on the site. The percentages of particles less than 0.02 mm in diameter must also be determined. This analysis is conducted before construction starts and is reported with the Permit Registration Documents (PRDs). 7.5 Watershed Monitoring Option Dischargers who are part of a qualified regional watershed-based monitoring program may be eligible for relief from the sampling and analysis requirements. The RWQCB may approve proposals to substitute an acceptable watershed-based monitoring program by determining if the watershed-based monitoring program will provide substantially similar monitoring information in evaluating discharger compliance with the requirements of the General Permit. 7.6 Monitoring Exemptions Dischargers are not required to physically collect samples or conduct visual observations during dangerous weather conditions (flooding, electrical storms, etc.) or outside of scheduled construction site business hours. An explanation must be provided in the annual Report is a project was unable to collect required samples or visual observations because of dangerous weather conditions. 7.7 Quality Assurance /Quality Control An effective QA/QC plan will be implemented as part of the CSMP to ensure that analytical data can be used with confidence. QA/QC procedures to be initiated include the following: Field logs; Clean sampling techniques; Sample Chains of Custody (COCs); and Data verification Each of these procedures is discussed in more detail in the following sections. A. Field Logs Section _SWPPP.doc Page 7-14

44 The purpose of field logs is to record sampling information and field observations during monitoring that may explain any uncharacteristic analytical results. Sampling information to be included in the field log include the date and time of water quality sample collection, sampling personnel, sample container identification numbers, and types of samples that were collected. Field observations should be noted in the field log for any abnormalities at the sampling location (color, odor, BMPs, etc.). Field measurements for ph and turbidity should also be recorded in the field log. Field log to record visual inspections and sample collection and field measurements are provided in Appendix N. B. Clean Sampling Techniques Clean sampling techniques involve the use of certified clean containers for sample collection and clean powder-free nitrile gloves during sample collection and handling. As discussed previously, adoption of a clean sampling approach will minimize the chance of field contamination and questionable data results. C. Sample Chain-of-Custody The sample COC is an important documentation step that racks samples from collection through analysis to ensure the validity of the sample. Sample COC procedures include the following: Proper labeling of samples; Use of COC forms for all samples; and Prompt sample delivery to the analytical laboratory. Analytical laboratories usually provide COC forms to be filled out for sample containers. D. Data Verification After analytical results are received from the analytical laboratory, the data should be verified to ensure that it is complete, accurate, and the appropriate QA/QC requirements were met. Data should be verified as soon as the data reports are received. The COC and laboratory reports need to be checked to make sure all requested analysis were performed and all samples are accounted for in the reports. Check laboratory reports to make sure hold times were met and that the reporting levels meet or are lower than the reporting levels agreed to in the contract. Check data for outlier values and follow up with the laboratory. Occasionally typographical Section _SWPPP.doc Page 7-15

45 errors, unit reporting errors, or incomplete results are reported and should be easily detected. These errors need to be identified, clarified, and corrected quickly by the laboratory. Attention should be paid to data that is an order of magnitude or more different than similar locations, or is inconsistent with previous data from the same location. For laboratory analyses, EPA establishes QA/QC checks and acceptable criteria. These data typically reported along with the sample results. Data reviewers should evaluate the reported QA/QC data to check for contamination (look at method, field, and equipment blanks), precision (laboratory matrix spike duplicates), and accuracy (matrix spikes and laboratory control samples). When QA/QC checks are outside acceptable ranges, the laboratory must flat the data, and usually provides an explanation of the potential impact to the sample results. Check the data set for outlier values and, accordingly, confirm results and re-analyze samples where appropriate. Sample re-analysis should only be undertaken when it appears that some part of the QA/QC resulted in a value out of the expected range. Initial data, even if outside the expected range may not be discounted unless the analytical laboratory identifies the required QA/QC criteria were not met. If this occurs, the project should obtain a written statement from the analytical laboratory regarding the validity of the sample result. Similarly, field data needs to be checked as soon as possible to identify potential errors. Reported data and observations should be verified to ensure that it is complete and accurate and as soon as the field logs are received. Field logs should be checked to make sure all required measurements were completed and appropriately documented. Crews may occasionally miss-record a value. Reported values that appear out of the typical range of inconsistent, should be followed up on immediately to identify potential reporting or equipment problems. Equipment calibration notations should be verified for outlier data, and if appropriate equipment calibrations should be checked after sampling. Observations noted on the field logs can also help to identify potential interferences. Notations should be made of any errors and actions taken to correct the equipment or recording errors. When using a field meters it is important to record the value and then make note of any possible meter failures or interferences that could have led to an exceedance. Some possible instrument problems may include the need to recalibrate; the need to replace the batter; problems with the sample container (such as scratches on glass or plastic optical sample cells or particles on the outside of the optical sample cells); or fouled probes. 7.8 Reporting and Records Retention Most reporting will typically occur in the Annual Report. Section _SWPPP.doc Page 7-16

46 A. Numeric Action Level Exceedance Report Storm Water Pollution Prevention Plan (SWPPP) In the event that the storm event average of the samples exceeds an applicable NAL, Risk Level 2 and 3 dischargers must electronically submit all storm event sampling results to the SWRCB s SMARTS no later than 10 days after the conclusion of the storm event. (Note, however that Risk Level 3 dischargers must submit all field data regardless of exceedance status within five days of the storm event conclusion). In addition, the RWQCBs may request the submittal of an NAL Exceedance Report. The discharger must certify each NAL Exceedance Report in accordance with the General Permit s Special Provisions for Construction Activity. An NAL Exceedance Report must contain the following information: Analytical method(s), method reporting unit(s), and MDL(s) of each analytical parameter; Date, place, time of sampling, visual observation (inspections), and/or measurements, including precipitation; and Description of the current BMPs associated with the sample that exceeded the NAL and the proposed corrective actions taken. B. Annual Report All dischargers are required to prepare and electronically submit an Annual Report no later than September 1 each year. The Annual Reports must be certified in accordance with the Special Provision in the General Permit. The Annual Report must include the following stormwater monitoring information: A summary an evaluation of all sampling and analysis results, including original laboratory reports; The analytical method(s), method report unit(s), and MDLs) of each analytical parameter (analytical results that are less than the MDL must be reported as less than the MDL or <MDL ); A summary of all corrective actions taken during the compliance year; Identification of any compliance activities or corrective actions that were not implemented; A summary of all violations of the General Permit; The individual(s) who performed facility inspections, sampling, visual observation (inspections), and/or measurements; The date, place, time of facility inspections, sampling, visual observation (inspections), and/or measurements, including precipitation (rain gauge); and The visual observations and sample collection exception records and reports. Section _SWPPP.doc Page 7-17

47 C. Records Retention Dischargers must retain records of all stormwater monitoring information and copies of all reports (including Annual Reports) for a period of at least three years from the date of submittal or longer if required by the RWQCB. ATS dischargers must retain all records for three years after the completion of the construction project. Records are to be kept on site while construction is ongoing. These records include: The date, place, and time of facility inspections, sampling, visual observations (inspections), and/or measurements, including precipitation; The individual(s) who performed the facility inspections, sampling, visual observation (inspections), and/or measurements; The date and approximate time of analyses; The individual(s) who performed the analyses; A summary of all analytical results from the last three years, the method detection limits and reporting limits, and the analytical techniques or methods used; Rain gauge readings from the site inspections; QA/QC records and results; Non-stormwater discharge inspections and visual observations (inspections) and stormwater discharge visual observation records; Visual observation and sample collection exemption records NAL Exceedance Reports and NEL Violation Reports; and The records of any corrective actions and follow-up activities that resulted from analytical results, visual observations (inspections), or inspections. Results of field measurements and laboratory analyses must be kept in the SWPPP. It is also recommended that training logs, COCs, and other documentation related to sampling analysis be kept with the project s SWPPP. Section _SWPPP.doc Page 7-18
