I. Introduction and Certifications

I.A. SWPPP Objectives

This SWPPP has been developed for the Camp Richardson Resort Campground Retrofit Project to comply with the requirements to implement BMPs to achieve compliance with effluent limits and receiving water objectives as directed by the Construction General Permit for the Lake

Tahoe Hydrologic Unit (Board Order R6T-2011-0019, NPDES No. CAG616002). This SWPPP has been developed and will be amended, when necessary, to meet the following objectives:

1. Identify, construct, implement and maintain BMPs to reduce or eliminate pollutants in storm water discharges and authorized non-storm water discharges from construction sites.

2. Identify pollutant sources including sediment sources that may affect the quality of storm water discharges associated with construction activity.

3. Identify non-storm water discharges.

4. Identify all effluent discharge outfall locations, sampling and analysis strategy and protocols, and a sampling schedule for discharges from the identified outfalls from the project area.

I.B. SWPPP Implementation Schedule

The specific construction schedule will be determined by the contractor when a contractor is selected for this work. The project at Badger’s Den Campground on the North side of Highway

89 and the construction of the day use restroom near the Beacon Bar and Grill is planned for summer of 2015. The project at Eagle’s Nest Campground on the South side of Highway 89 is planned for summer of 2016. There are several aspects of the construction that will be controlled by the Forest Service, including:

Construction will occur between May 1 and October 15.

Micro-basins will be one of the first features constructed. They will be used as a BMP to capture storm water flows from open graded or impervious surfaces.

Temporary BMPs (such as silt fence at the day use restroom) will be required to be on site prior to any grading.

II. Project Information

II.A. Project Description, site address and driving directions

The Camp Richardson Resort Campground Retrofit project will renovate existing campgrounds within the Camp Richardson Resort. The project will consist of reconstructing Badger’s Den

Campground, reconstructing Eagle’s Nest Campground, and building a day-use restroom.

Badger’s Den Campground and the day-use restroom are scheduled for implementation in May

2015. Eagle’s Nest Campground is scheduled to begin construction in May of 2016.

The project is located in South Lake Tahoe, CA adjacent to Highway 89. It is located in Section 6 of Township 13N, Range 18E, and covers approximately 35 acres (see Figure 1).

II.A.1. Badger’s Den Campground

Badger’s Den Campground is currently a Forest Service campground on the north side of

Highway 89. It is bordered by Pope Beach Road to the east, and a thick line of SEZ vegetation to the north. It consists of native surface roads and campsites that are undefined and unrestricted, which has resulted in excess disturbance and compaction. Several campsites are currently within the SEZ boundary.

Badger’s Den Campground Reconstruction is scheduled to start in May, 2015 (see Figure 2). This project will define roads and campsite areas to decrease excess disturbance. Roads and campsites will be paved, and approximately 5,600 square feet of current disturbance in the SEZ will be removed by decompacting and mulching the areas. 84 campsites will be constructed, including single and double sites, and living areas with tent pads and site amenities will be attached to each. Infiltration basins will be constructed to capture storm water from impervious surfaces. They will be constructed prior to uphill ground disturbing activities and establishment of staging areas, so as to serve as both temporary and permanent BMPs. Site grading will ensure that surface storm water drains to these infiltration basins. Within the project boundary, the highly used Pope-Baldwin National Recreation Trail will be re-routed away from the highway, creating a safer buffer distance from the crowded Camp Richardson highway corridor. A drainage swale will be established for the outflow from the large basin in the southwest corner of Badger’s Den Campground and between the culverts near Highway 89 (see

Figure 2) and will include stabilization of outflows and sides of drainage swales with rock armoring. Arrays of 3 – 24” culverts will convey storm water under the proposed bike path and campground road. These culverts are consistent with the capacity of CalTrans conveyance under the highway (upstream crossing), with performance requirements indicated in project hydrology and hydraulic analysis, and will accommodate a 100-year flood flow without overtopping. 227 trees between 6” and 36” dbh will be removed as part of this project. Tree removal will include felling, limbing, bucking, stump removal, decking, and chipping. The same

BMPs will be used for tree removal as in the rest of the project.

II.A.2. Eagle’s Nest Campground

Eagle’s Nest Campground is very similar to Badger’s Den, and is currently a Forest Service campground on the south side of Highway 89. It also consists of native surface roads and campsites that are undefined and unrestricted. It is connected to the west by a dirt road leading to the Camp Richardson RV Campground.

Eagle’s Nest Campground Reconstruction is scheduled to start in 2016 (see Figure 3 and 4).

Because design for this campground is not yet complete, final drawings will be added to the

SWPPP prior to construction. This project will have the same goals as Badger’s Den

Campground Reconstruction, such as defining paved roads and campsites, as well as with constructing infiltration basins to capture storm water from impervious surfaces. The main campground kiosk will be built near the entrance, followed by a paved roundabout to easily access other amenities in Camp Richardson Resort. A group loop will be constructed to the east to accommodate for large parties of campers. Two more camping loops will be constructed west of the group loop, each containing tent pads and site amenities. A double lane paved road will also be constructed leading west from the roundabout to the RV campground (see Figure

4).

II.A.3. Day-use Restroom

A new day-use restroom will be constructed just west of the Beacon Bar and Grill (see Figure 5).

The restroom will be located near the beach and have electrical, water, and sewer utilities. It will be located above the Lake Tahoe high water mark (6229’) and outside of SEZ boundaries.

Permanent infiltration basins will be constructed to capture storm water during and after construction.

III. Best Management Practices

III.A. Site Management Narrative

Construction site management shall consist of controlling potential sources of pollution before they come in contact with storm water systems or watercourses. Potential sources of pollution may include storm water over newly graded areas, asphalt grindings, uncompacted pavement, concrete waste, open sewer piping, or stockpiles. Other potential pollutants may include improperly functioning portable restrooms, fluids from mechanical equipment used on site, or excessive dust. See Tables 2 – 5 for specific CASQA BMPs used to mitigate these possible pollutants. Appropriate site management measures shall be implemented to control material pollution and manage waste by implementing effective handling, storage, use and disposal practices. Additionally, many non-storm water pollution control BMPs (below) are necessary for proper site management.

Waste management and materials pollution control BMPs shall be implemented to minimize storm water contact with construction materials, wastes and service areas and to prevent materials and wastes from being discharged off-site. The primary mechanisms for storm water contact that shall be addressed include:

Direct contact with precipitation

Contact with storm water run-on and runoff

Wind dispersion of loose materials

Direct discharge to watercourses and Lake Tahoe through spills or dumping

The following Waste Management and Materials Pollution Control BMPs Table indicates the

BMPs that shall be implemented to handle materials and control construction site wastes associated with these construction activities. See Appendix B for identified CASQA specifications.

The following list of BMPs and narrative explain how the selected BMPs will be incorporated into the project. Where CASQA fact sheets contradict information contained in the Technical

Specifications or the Drawings, the QSD shall determine which criteria applies. Selection criteria will be documented in a SWPPP Amendment.

WM-1, WM-2 Materials Delivery, Storage and Use

In general, BMPs shall be implemented to help prevent discharges of construction materials during delivery, storage and use. See Figure 2 and 3 for specific staging areas. Materials, equipment, stockpiles, spoils, and waste will be limited to already disturbed and flat areas. A barrier shall be provided along the downslope edge of the staging areas to prevent runoff leaving the area. If the QSP determines there is a risk of run-on, a barrier shall be provided along the upslope edge of the staging area.

WM-3 Stockpile Management

Stockpile Management shall be implemented to reduce or eliminate pollution of storm water from stockpiles of soil and rock materials. Any stockpiles will be located in already disturbed and flat areas. All stockpiles will be located to avoid run-on. Stockpiles shall be surrounded with sediment controls, and if a soil stockpile is inactive for 14 days it will be stabilized with hydraulic mulch or geotextile. If any soil or other erodible material is stockpiled over the winter, it will be covered with hydraulic mulch by October 15

WM-4 Spill Prevention and Control

Spill Prevention and Control shall be implemented to contain and clean up spills, and to prevent material discharge to waterways.

WM-5, WM-6, WM-10 Solid, Liquid, and Hazardous Waste Management

Solid Waste Management, Liquid Waste Management, and Hazardous Waste Management

BMPs shall be implemented to minimize storm water contact with waste materials and prevent waste discharges. Solid wastes (trash) shall be disposed of offsite daily. If onsite storage is necessary, solid wastes shall be stored inside a locked storage container.

Liquid hazardous waste shall be disposed of offsite the same day it is generated. If it is necessary to store liquid hazardous waste, it will be stored in the same storage container referenced above. Hazardous wastes shall be contained in appropriate and clearly marked containers and segregated from other non‐waste materials. All hazardous waste shall be stored, transported and disposed as required.

WM-8 Concrete Waste Management

All concrete waste, including concrete washout, shall be collected and taken offsite. A majority of concrete will be underground (i.e. gate posts).

WM-9 Sanitary and Septic Wastes

Portable toilets shall be located and maintained at the staging areas for the duration of the project. Specific locations will be determined in the field by the QSD. Weekly maintenance shall be provided and wastes shall be disposed offsite. The toilets shall be located away from concentrated flow paths. Toilet location shall not interfere with traffic flow.

III.B. Sediment and Erosion/Stabilization Control Narrative

III.B.1. Erosion Control

Erosion control is any source control practice that protects the soil surface and prevents soil particles from being detached by rainfall, flowing water or wind. Erosion control consists of using project scheduling and planning to reduce soil and/or vegetation disturbance, controlling drainage in disturbed areas and preparing and stabilizing disturbed soil areas.

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

Preserve existing vegetation; disturbed soil areas are displayed on Figures 2 – 5, existing vegetation will be preserved outside of these boundaries;

The area of soil disturbing operations shall be controlled such that either erosion control

BMPs (Table 3) can be quickly and effectively implemented or the site can be permanently stabilized in that area;

Stabilize drainage swale side slopes and outflows with rock armoring.

Non-active areas will be stabilized within 14 days of cessation of construction activities;

Prior to the completion of construction, apply permanent stabilization to disturbed soil areas.

Sufficient erosion control materials shall be maintained onsite to allow implementation in conformance with this SWPPP. This includes implementation requirements for active and non-active areas that require deployment of BMPs before the onset of rain.

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

WE-1 Wind Erosion Control

Specifications or the Drawings, the more stringent criteria (as determined by the QSD) shall apply. Selection criteria will be documented in a SWPPP Amendment.

EC-1, EC-2 Scheduling, Preservation of Existing Vegetation

Surface disturbance activities will begin May 1 and continue no later than October 15. Grading activities are scheduled to be completed prior to October 3, ensuring enough time for winterization activities before the October 15 grading deadline. A grading ordinance exemption may be requested from TRPA and LRWQCB if the QSD and Project Engineer deem it necessary and appropriate to work past October 15. When there is a 30 percent or greater chance of precipitation in the project area as predicted by the National Oceanographic and Atmospheric

Administration (NOAA), further actions may be taken (see section IV.B. Rain Event Action Plan

Narrative).

The project schedule will sequence construction activities with the installation of both soil stabilization and sediment control measures. Micro-basins and/or other temporary BMPs will be constructed before major ground disturbing activity begins, in order to capture stormwater flows from open graded or impervious surfaces. BMPs will be deployed in a sequence to precede the progress of grading and construction (including staging areas and tree removal).

The construction schedule will be arranged as much as practicable to leave existing vegetation and other ground cover undisturbed until immediately prior to grading. See Figures 2 – 5 for disturbed soil areas; existing vegetation will be preserved outside of these displayed boundaries. Construction fencing may be used as a safety precaution during construction.

EC-3 Hydraulic Mulch

Soil stockpiles that are not actively being used will be covered with hydraulic mulch or a plastic cover.

EC-8, EC-16 Wood Mulching, Non-Vegetated Stabilization

Decompaction of soils and application of wood mulch will be used in combination with slash material as long‐term stabilization for disturbed areas that will not be paved upon completion of the project. These areas include staging and stockpile areas as well as disturbed areas inside the SEZ.

Wood mulch may be used to cover small exposed soil areas that have the potential to release sediment discharge to a live waterbody prior to a forecast storm event. If wood mulch is used in such an instance it shall be applied to depth that will protect soil and prevent movement to mulch (approximately 2”– 4”).

EC-9 Drainage Swales

Drainage features, such as pavement outsloping and shoulder grading, will be used as permanent BMPs to convey water from travel surfaces. See Figures 2 – 5 for locations of infiltration basins, where water will be conveyed to.

EC-10 Velocity Dissipation Devices

A rock velocity dissipation device will be used at the outlet of all culverts and micro basins.

EC-15 Soil Preparation / Roughening

Compacted areas to be restored will be decompacted to increase water infiltration capacity. A uniform decompaction of the soil will be accomplished to a depth of 6 to 12 inches.

WE-1 Wind Erosion Control

Water shall be applied to disturbed areas to control dust, and the water will be applied using water trucks. Water application rates will be minimized as necessary to prevent runoff and ponding. Water equipment leaks will be repaired as soon as possible. Material stockpiles may also be watered if wind erosion is evident.

III.B.2. Sediment Control

Sediment controls are structural measures that are intended to complement and enhance the selected erosion control measures and reduce sediment discharges from construction areas.

Sediment controls are designed to intercept and settle out soil particles that have been detached and transported by the force of water. Additional temporary sediment control materials will be maintained onsite throughout the duration of the project, ready for implementation in an anticipated precipitation event (see Section IV.B. Rain Event Action Plan

Narrative for protocol during an anticipated precipitation event), rapid response to failures, or emergencies, as described below. This includes implementation requirements for active areas and non‐active areas before the onset of rain. The following sediment control BMP selection table (Table 4) indicates the BMPs that shall be implemented to control sediment on the construction site.

SE-1 Silt Fence

Within the day-use restroom site, silt fence will be installed on the downhill side of the project area. If precipitation occurs, and before disturbed soil area runoff occurs, silt fence may be installed to contain erosion from openly graded areas.

SE-2 Sediment Basin

Permanent infiltration basins will be constructed before any major grading begins. The basins will be built to capture the eroded or disturbed soil that is washed off during storms, and protect the quality of all nearby surface water.

SE-5 Fiber Rolls

Fiber rolls will be used to surround any stockpile area that is inactive for more than 14 days or when there is an anticipated precipitation event (see Section IV.B. Rain Event Action Plan

Narrative for a definition of an anticipated precipitation event). They may also be used to stabilize newly graded slopes during the threat of precipitation. Additional fiber rolls will be kept on-site to be deployed as needed.

SE-7 Street Sweeping

If tracking is evident due to construction, the excess sediment from the project site will be broomed to an area where it won’t be carried away by storm water flows.

TC-1, TC-2 Stabilized Construction Entrance/Exit, Entrance Outlet Tire Wash

Tracking will not occur off Forest Service property. Brooming will be the main BMP used to prevent tracking off of Forest Service property. If this is not sufficient as determined by the

QSP, a stabilized exit and/or a tire wash may be used.

III.C. Non-Storm water and Material Management Narrative

The selection of non‐storm water BMPs is based on the list of construction activities with a potential for non‐storm water discharges identified above. The following non‐storm water control BMP selection table (Table 5) indicates the BMPs that shall be implemented to prevent non‐storm water discharges at the construction Site.

Water application rates will be minimized as necessary to prevent runoff and ponding. Water equipment leaks will be repaired immediately. If irrigation is used to establish vegetation, irrigated areas within the construction limits will be inspected for excess watering and watering times and schedules will be adjusted to ensure that the appropriate amount of water is being used and runoff is avoided.

NS-3 Paving and Grinding Operations

Asphalt waste will be disposed of offsite. Any material produced from potential grinding operations may be used as base in non-SEZ areas. Micro-basins will be in place to capture storm water flow from paved surfaces.

NS-6 Illicit Connection and Illegal Discharge Connection

The LTBMU will implement the Illicit Connection/Illegal Discharge Detection Reporting BMP throughout the duration of the project.

NS-8, NS-9, NS-10 Vehicle and Equipment Operations

Vehicle and Equipment Fueling (NS-9), and Vehicle and Equipment Maintenance BMPs (NS-10) will be utilized to prevent discharges of fuel and other vehicle fluids. Vehicles will be cleaned and inspected (NS-8) prior to arrival on site. Vehicle cleaning will not be performed onsite, except as part of normal maintenance to remove excess dirt/mud from equipment. This type of cleaning will take place within the staging area (BMP area) and be performed such that runoff is not generated; wash water will be contained within the project area.

Fuel trucks, each equipped with absorbent spill clean‐up materials, shall be used for all onsite fueling. Drip pans or absorbent pads shall be used during all vehicle and equipment maintenance activities that involve grease, oil, solvents, or other vehicle fluids. All vehicle maintenance shall be conducted at least 50 feet away from stream channels and on a level graded area. If mobile maintenance is necessary due to an equipment failure within the construction area that prevents the equipment from be moved to a staging area, drip pans and/or absorbent pads shall be used to prevent any contamination of the site.

NS-12, 13 Concrete Curing, Concrete Finishing

There will be concrete used for the following portions of this project: building foundation, gate post and faucet installations, and sewer and water underground utility relocations. Any surface concrete curing will be covered during predicted storms, and will not affect surface waters.

III.D. Dewatering and Diversion Plan Narrative No dewatering and diversion actions are planned as part of this project. Culverts will be installed only when channels are dry.

III.E. Active Treatment System Plan Narrative

No active treatment system operations are planned as part of this project.

III.F. Post-Construction Storm Water Management Measures Narrative

All features constructed during this project, including roads, camping spurs, and drainages are designed to function during storms. Micro-basins will be designed to handle the capacity of a two inch in 24-hour storm, and runoff from new asphalt will be collected in these basins. This project will be monitored post-construction to determine if the roads, camping spurs, and drainages are functioning as designed. See Section V.B. Visual Inspections for further monitoring information. In addition, the Forest Service National BMPEP protocol will be used to evaluate this project. This national protocol can be found at the following website:

http://fsweb.wo.fs.fed.us/wfw/watershed/national_bmps/bmp_docs-recreation.html

III.G. Schedule for BMP Implementation

BMPs will be implemented, modified, and maintained appropriately for the site and weather conditions encountered during the project. Fiber rolls will be placed at the base of all material stockpiles, and material piles will be watered if excessive wind erosion is occurring.

III.H. BMP and Disturbed Soil Area maps

Figures 2 through 5 show the disturbed soil areas (DSAs), drainage crossings, and staging area

BMPs for this project. Orange construction fence will be placed along project boundaries.

Section IX. H. Mapping Requirements, of the R6T-2011-0019 requires that DSA maps be of a scale no smaller than 1 inch equals 50 feet (1:600). Figure 1 displays the entire project and does not meet this requirement. Because of the large area of this project, only key areas are shown on maps to this scale (Figures 2 – 5).

IV. BMP Inspection, maintenance and Rain Event Action Plans

IV.A. BMP Inspection and Maintenance Narrative

The General Permit requires that an inspection of the construction site be made at the end of each work day and before, during, and after rain events. Additionally, during the winter or inactive periods, inspections must be conducted at least once per month during daylight hours.

During some months, a visual inspection may not be possible because of excessive snow covering the ground. Monthly inspections will continue through the Spring following final construction to ensure permanent soil stabilization measures function through Spring runoff.

The purpose of the inspections is to discover potential water quality problems so that corrective measures can be implemented immediately. A BMP inspection checklist will be filled out for each inspection and maintained on-site with the SWPPP. A blank inspection checklist can be found in Appendix D. Completed checklists shall be kept with the SWPPP. Inspections of

BMPs are 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.

IV.B. Rain Event Action Plan Narrative

The Rain Event Action Plan (REAP) is a document designed to be used as a planning tool by the

QSP to protect exposed portions of the project sites prior to and during precipitation events 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 generated during a rain event. It is the responsibility of the QSP to be aware of precipitation forecasts and to obtain and keep copies of forecasted precipitation from NOAA’s National Weather Service Forecast Office

(http://srh.noaa.gov/forecast).

The SWPPP includes REAP templates, but the QSP will need to customize them for each rain event, to reflect site conditions related to current phase of construction. A site-specific REAP template can be found in Appendix E. Completed REAPs shall be maintained on-site with the SWPPP. Additionally, a printed copy of the forecast for each day of forecast precipitation shall be kept with the SWPPP monitoring records.

The QSP will develop an event-specific REAP no later than the calendar day 24 hours prior to any anticipated precipitation event. An anticipated precipitation event is any weather pattern that is forecast to have a 30 percent or greater chance of producing precipitation as rainfall in the project area as predicted by the National Oceanographic and Atmospheric Administration

(http://www.srh.noaa.gov/). During periods when thunderstorm activity is anticipated, weather conditions shall be monitored during the course of the day. If the chance of thunderstorms becomes 30 percent or greater, or when visual observations indicate imminent precipitation, the QSP shall prepare and implement a REAP.

The REAP will be onsite and implemented no later than 24-hours in advance of a predicted precipitation event or if predicted less than 24-hours in advance, as soon as possible. At a minimum the REAP shall include the following site and phase-specific information:

QSP name and contact number;

The date(s) rain is predicted to occur, and predicted chance of rain;

A description of all DSAs, material storage areas, stockpiles, vehicle and equipment storage and maintenance areas, and waste management areas. These areas must be cross-referenced to BMP plans or DSA maps by sheet or page number;

For each area described above, list specific items to review and actions to perform prior to the rain event;

A certification by the QSP that the REAP will be carried out as required by the General

Permit; and

A printout of the NOAA weather forecast

The REAP must be checked and updated daily for storms expected to last over a period of several days.

http://www.srh.noaa.gov/

V. Construction Site Monitoring and Reporting Plan (CSMRP)

V.A. Purpose

This Construction Site Monitoring Plan was developed to address the following objectives:

Demonstrate that the site is in compliance with the discharge prohibitions and applicable effluent limitations;

Determine whether non-visible pollutants are present at the construction site and are causing or contributing to exceedance of water quality objectives;

Determine whether immediate corrective actions, additional BMPs, or SWPPP revisions are necessary to reduce pollutants in storm water discharges and authorized non-storm water discharges;

Determine whether BMPs included in the SWPPP/REAP are effective in preventing or reducing pollutants in storm water discharges and authorized non-storm water discharges; and

Demonstrate that appropriate sample collection, handling and analysis procedures are implemented.

V.B. Visual Monitoring

During the active construction season, an inspection of the construction site shall be made at the end of each work day. Additionally, during the inactive period, inspections must be conducted at least once per month during daylight hours. Monthly inspections may not occur during winter months if site is covered in snow.

During both active and inactive periods, a construction site inspection shall also be performed within the 24-hour period prior to an anticipated rain event (chance of precipitation is forecasted at 30 percent or greater), daily during the event, and within 24 hours after actual storm events. This requirement does not apply during snow events. Inspections shall be documented on the BMP Inspection Checklist (Appendix D) and kept with the monitoring records with the SWPPP. If inspections cannot be completed within the specified time frames, the reason for the delay shall be recorded in writing and maintained with the next inspection report.

Visual observations will be made at all active areas of construction. In addition, visual observations must be made at all designated effluent outfalls and locations where storm water may discharge from the project boundary, such as at each infiltration basin at the day use restroom site if overflow occurs.

After the completion of construction, additional visual monitoring will take place at least once during the Spring, Summer, and Fall to ensure project actions were effective.

Each micro-basin will be inspected to find evidence of its success. If evidence of failure of any of the above measures exists, the Forest Service will take further action. For example, if evidence of erosion is found circumventing the newly constructed micro-basins, these basins may be reconstructed to fully capture future storm flows. If vegetative cover is not adequate as determined by a Forest Service botanist, more vegetation may be planted or more native seed with hydromulch may be placed.

In addition, the newly updated Forest Service National BMPEP protocol will be used to evaluate this project. The protocol from “Recreation Management A” will be used to evaluate the effectiveness of BMP construction for this project. This national protocol can be found at the following website:

http://fsweb.wo.fs.fed.us/wfw/watershed/national_bmps/bmp_docs-recreation.html

V.C. Water Quality Sampling and Analysis

Storm water runoff generated from the project area which is discharged to surface waters must not contain constituents in excess of the following numeric effluent limitations (NELs):

Table 8. Storm Water Effluent Limitations

Parameter Units Maximum Daily Effluent Limitation for Discharge

Total Nitrogen (N) mg/L 0.5

Total Phosphorus (P) mg/L 0.1

Total Iron mg/L 0.5

Turbidity NTU 20

Grease and Oil mg/L 2

Total Nitrogen, Total Phosphorus, Total Iron, and Grease and Oil will only be sampled if there is reason to believe it is present in excess amount as a result of project activities, or there are visual indicators (Grease and Oil) that a substance is present in the storm water runoff.

Additionally, waters generated within the project area that are discharged to surface waters must not contain the following:

Substances in concentrations that are toxic to, or produce detrimental physiological responses in human, plant or animal life; and

Coliform organisms attributable to human wastes.

Samples will not take place for these substances unless there is reason to believe they are present.

For protection of receiving waters the pH of effluent samples should not fall outside of the range of 6.0 to 9.0. Concrete placement is extremely minor, and no impact is expected to occur on receiving waters. Because no activity of the project is expected to affect pH, samples will not be taken unless there is reason to believe that pH levels are adversely impacted.

In addition, storm water runoff turbidity samples will be taken from visible surface water discharge locations deriving from newly constructed areas and overflow from the day use restroom infiltration basins, as applicable. Water samples will be collected by the Forest Service during the first two hours of discharge from rain events or as soon as staff are able to get to the site if rain event occurs outside of normal construction time. A minimum of three samples will be collected each day storm water that is derived from new construction is discharged off site to receiving waters. These water samples will document BMP effectiveness and ensure ambient water quality is not degraded. Water samples will be collected during daylight hours (sunrise to sunset) during the event and cease when turbidity falls to background levels. Water samples will not be collected if unsafe conditions exist.

V.D. Watershed Monitoring Option

This project consists of routine road construction and drainage restoration and does not require additional monitoring of the watershed.

V.E. Quality Assurance and Quality Control

For initial verification of field analysis, duplicate samples shall be collected at a rate of 10 percent or one minimum duplicate per sampling event for the first three days of the project or whenever there is an addition of a sampler. The duplicate samples shall be collected, handled and analyzed using the same protocols as primary samples. A duplicate sample shall be collected at each location immediately after the primary sample has been collected. Duplicate samples shall not influence any evaluations or conclusions; however, they will be used as a check on quality assurance.

V.F. Reporting Requirements and Records Retention

V.F.1. Record Keeping

The following shall be retained for a minimum of three years:

Approved SWPPP document and amendments;

Site Inspection Reports;

Site Inspection Report Corrections Summary;

Rain Event Action Plans;

Notice of Discharge reports;

Numeric Effluent Limit (NEL) Exceedance Reports;

Sampling records and analysis reports;

Annual Compliance Certifications; and

Copies of all applicable permits.

V.G. Non-Compliance Reporting

V.G.1. 24-Hour Reporting

The discharger shall immediately notify the Lahontan Water Board orally…
