1.0 INTRODUCTION
1.1 Site Summary
Old Durham Wood, Inc. (ODW), is a wood-processing facility that converts orchard wood into
chips for biomass, lumber, firewood, and fines. The site has historically also received greenwaste
from the City of Chico, Butte County, Paradise, and Sacramento Municipal. The wood fines
generated and greenwaste received have historically been combined and composted onsite.
The site is currently covered under General Waste Discharge Requirements for Composting
Operations (Order WQ 2015-0121 DWQ) or CGO. The CGO requires ODW to retain onsite
all stormwater which contacts the compost. This has proved difficult for ODW, and ODW has
made the management decision to no longer compost onsite during the winter months. Any
composting that is undertaken will be conducted during the summer (dry season). Any residual
compost onsite will be covered prior to winter. Therefore, stormwater from the site may be
discharged under the General Permit for Stormwater Discharges Associated with Industrial
Activity (Order 2014-0057-DWQ) or IGP. The general site location is shown on Figure 1.
The site is divided into specific areas for chipping and grinding of wood material, milling, and
firewood packaging and storage. Site layout is shown on Figure 2.
Stormwater discharging from the site has historically entered Hamlin Slough just south of the
facility. Previously, the site was not regulated under the IGP as both firewood and chipping and
grinding are not covered SIC codes. ODW had until October 2022 to retain all stormwater
from composting operations. Some discharge occurred during the 2019 winter season. Based
on the sampling conducted in 2018 and 2019, the discharge from the facility most resembles
discharges from other wood processing facilities. Following discussions with the Regional Water
Board, it was determined that the use of the IGP for the facility was appropriate based on wood-
processing activities conducted onsite, although not specifically addressed by SIC code.
In response to the need to retain all stormwater onsite, ODW purchased the additional property
to the site to use for water retention; however, due to the large cost for wetlands mitigation, the
pond costs became prohibitive. Instead, ODW intends to use the historical rice fields as a
biofilter to filter stormwater from the site prior to discharge to Hamlin Slough. The piping
system is currently being installed, the rice checks repaired, and additional boxes installed to
better control the direction and flow of water through the checks. The final discharge point for
the filter system will be determined following the check repairs now ongoing. An approximate
discharge location is shown on Figure 2. This will be the only proposed discharge point for the
facility. All stormwater from the site will be pumped through the filter system.
Facility information is summarized below.

1.2 SIC Codes
40 CFR §122.26(b) (14) defines “stormwater discharge associated with industrial activity” and
describes the types of facilities subject to permitting (primarily by Standard Industrial
Classification (SIC) code). This General Permit provides regulatory coverage for facilities with
the industrial activities described in the permit where the covered industrial activity is the
Discharger’s primary industrial activity. In some instances, a Discharger may have more than
one primary industrial activity occurring at a facility.
The 1987 SIC manual uses the term “establishment” to determine the primary economic activity
of a facility. The manual instructs that where distinct and separate economic activities are
performed at a single location, each activity should be treated as a separate establishment (and,
therefore, as a separate primary activity).
The SIC manual also discusses “auxiliary” functions of establishments. Auxiliary functions
provide management or support services to the establishment. Examples of auxiliary functions
are warehouses and storage facilities for the establishment’s own materials, maintenance and
repair shops of the establishment’s own machinery, automotive repair shops or storage garages
of the establishment’s own vehicles, administrative offices, research, development, field-
engineering support, and testing conducted for the establishment. When auxiliary functions are
performed at physically separate facilities from the establishment they serve, they generally are
not subject to General Permit coverage. If auxiliary functions are performed at the same
physical location as the establishment, then they are subject to General Permit coverage if they
are associated with industrial activities.
In 1997, the North American Industrial Classification System (NAICS) was published, replacing
the SIC code system. The U.S. EPA has indicated that it intends to incorporate the NAICS
codes into the federal stormwater regulations, but has not done so yet. Many Dischargers in
newer industries were not included in the 1987 SIC code manual and may have difficulty
determining their SIC code information.
October 2019 Page 3
P:\Projects\2017\71730 Old Durham Wood\SWPPP\ODW SWPPP October 2019.doc
The Old Durham Wood facility does not fall directly under a specific SIC code; however, the
discharge from the facility most resembles discharges from other wood-processing facilities.
Based on the sampling data and discussions with the Regional Water Board, the site will be
covered under SIC Code 2411 – Logging, as this SIC code is the only code dealing with chipping
and grinding, the primary activities undertaken onsite. This SIC code applies to establishments
primarily engaged in producing rough, round, hewn, or riven primary forest or wood raw
materials, or in producing wood chips – there is no SIC code to address firewood/cordwood.
1.3 Purpose of the Stormwater Pollution Prevention Plan
The preparation of a Stormwater Pollution Prevention Plan (SWPPP) is required by federal and
state regulation and is administered by the State Water Resources Control Board (SWRCB)
through the Regional Water Quality Control Board (RWQCB). This plan has been prepared to
comply with the terms of the General Permit for Stormwater Discharges Associated with
Industrial Activities (NPDES No. CAS000001, 2014-0057-DWQ). The intent of the order is to
protect water quality by controlling pollutants in stormwater runoff. This SWPPP is designed to
comply with Best Available Technology (BAT), Best Conventional Pollutant Control
Technology (BCT), and Best Management Practices (BMPs) to reduce or eliminate pollution
from industrial facilities during storm events.
1.4 Authority and Applicability
1.4.1 General Authority
Regional Water Boards are primarily responsible for enforcement of the Industrial General
Permit. The General Permit recognizes that Regional Water Boards have the authority to
protect the beneficial uses of receiving waters and prevent degradation of water quality in their
region. Dischargers of stormwater associated with industrial activity to waters of the United
States are required to meet all applicable requirements of the General Permit.
1.4.2 SIC Code Specific
Facilities classified as SICs 20XX through 39XX, identified as manufacturing facilities, are
subject to stormwater effluent limitation guidelines.
1.5 Implementation Schedule/Revisions
The BMPs detailed in this plan are implemented by ODW. Additional BMPs will be
implemented on an as-needed basis following analyses of stormwater sampling results.
The SWPPP will be updated whenever a change in the facility operations occurs that may
significantly affect the discharge of pollutants to surface water. Randy McLaughlin is
responsible for determining when SWPPP updates are required. Changes determined to be
necessary in the SWPPP will be forwarded to the RWQCB and included in copies of the SWPPP
that are retained onsite.
October 2019 Page 4

1.5.1 Performance Standards
This SWPPP was prepared to meet the performance standards outlined in the Industrial General
Permit (NPDES No. CAS000001, 2014-0057-DWQ). These standards include the following:
a. Identify and evaluate all sources of pollutants that may affect the quality of industrial
stormwater discharges and authorized non-stormwater discharges (NSWD);
b. Identify and describe the minimum BMPs and any advanced BMPs implemented to
reduce or prevent pollutants in industrial stormwater discharges and authorized NSWDs.
BMPs will be selected to achieve compliance with the General Permit; and,
c. Identify and describe conditions or circumstances which may require future revisions to
the SWPPP.
1.5.2 303(d) Applicability
Final discharge of stormwater from the facility is to Hamlin Slough, an intermittent tributary to
Butte Creek, hence to the Sacramento River. The location of Hamlin Slough is shown on
Figure 2. Butte Creek has been listed as impaired at the mouth with the Sacramento River for
the pesticides diazinon and molinate. The SWRCB has identified sources other than industrial
and, per Appendix 3 of the IGP, dischargers are not required to sample for that parameter.
Stormwater discharges from the ODW facility are not expected to contribute to these
impairments.

3.0 SITE INFORMATION
3.1 Facility Description
The ODW facility receives logs, woody debris, and chips. Chips may be stored onsite pending
need at a biomass facility. Material is chipped and ground onsite as well as imported from other
sites. Firewood is imported and packaged for sale.
3.2 Areas of Industrial Activity
3.2.1 Chipping and Grinding Operations
The general public and commercial businesses have historically delivered greenwaste to the
Public Green Waste Dumping station within the facility. Greenwaste is no longer being
accepted at the facility.
Woody debris that can be chipped for hog fuel continues to be received.
The length of time that the processed materials stay onsite depends on the needs of the
cogeneration power plants and compost area. At certain times of the year, cogeneration facilities
may stop accepting chips and materials would be stored onsite pending need. During the fall
and winter months, cogeneration power plants have a greater need for material to burn and they
accept more processed material.
3.2.2 Firewood Processing and Storage Operations
A Firewood Processing and Storage Operation includes the pruning and sale of orchard and
farm wood obtained from offsite or onsite sources, on a site occupying no more than 20 percent
of the parcel’s total size (approximately 18 acres), and where more than 100 cords of firewood is
stored for processing and offsite or onsite sales.
Wood used in the firewood-processing operations is harvested from area orchards. It consists
mainly of almond, walnut, and eucalyptus but can also include other types of orchard or farm
wood. Wood is cut offsite and loaded onto trucks and hauled into the project site to be stored
and cured. Logs brought to the site are unloaded with one of the wheel loaders and stacked.
When time permits, the logs are cut into firewood lengths for curing. The wood is cured until
the moisture content is below 20 percent, which generally takes 10 to 12 months. Cured wood is
then split in place using portable hydraulic wood splitters. Split firewood is assembled into
bundles, stacked on pallets, and shrink-wrapped. Firewood pallets are shipped from where they
are made or moved into the onsite building for storage. Up to 6,000 cords of wood are
processed every year. Commercial trucks ship the finished product to customers.
3.2.3 Composting Operations
Feedstock material for composting operations is generated from fines produced during chipping
and grinding operations. Composting feedstock is initially pushed into static piles until a
sufficient quantity of feedstock has been accumulated, at which point, composting feedstock is
October 2019 Page 7
P:\Projects\2017\71730 Old Durham Wood\SWPPP\ODW SWPPP October 2019.doc
transported by trailers or loaders into designated windrow areas. Approximately 30 to 35 acres
have been used for composting operations. Upon completion of the curing stage, the finished
compost is screened and transported for offsite sale. Composting will continue, but will only be
conducted in the dry summer months, when stormwater retention is not an issue.
3.2.4 Orchard/Farm Wood Processing Operations (Milling)
Wood used for offsite wood veneer production is obtained from area orchards and brought to
the site intermittently. Wood is initially cut offsite and then transported to the site by trucks.
Once onsite, the logs are trimmed to appropriate sizes using chainsaws and then milled into
square logs to be stacked on pallets to dry. When logs reach the appropriate moisture content,
logs are cut into 2-inch by 6-inch boards with the ripsaw and transported offsite for additional
processing. All scraps generated from processing operations become feedstock material for
chipping and grinding operations.
3.3 Materials Handling
The facility layout is shown on Figure 2.
3.3.1 Operations Equipment
Equipment that will be used at the facility includes:
Morbark 6600 Horizontal Grinder or Morbark 1300 Tub Grinder
Used in the processing of green waste materials into biomass and compostable materials.
Front-Wheel Loaders
There are always at least 2 front wheel loaders onsite at all times. They are used to feed
material up to and into the grinders, pushing of feedstock into piles for storage, loading
of biomass fuel and compost into trailers for transport, moving and turning of compost,
moving of firewood and firewood scraps, as well any other material-moving needs.
Powerscreen
Used for screening material from grinding operations to separate the fines (smaller
particles such as dirt) from the higher-quality biomass fuel. It will also be used for
screening finished compost product to remove large pieces prior to sale.
Truck Tipper
Used for removing the contents of a commercial truck trailer by raising the trailer to a
steep angle so that gravity will cause the material to slide out the back.
Water Truck
Used for suppressing dust caused by vehicles and grinding operations, fire suppression,
watering of compost to maintain moisture levels and lower temperatures, extracting
accumulations of water for distribution elsewhere and applying additives to the
composting piles.
Forklift
Used for unloading pallets, crates, and moving packaged firewood products for storage
or transport.
October 2019 Page 8
P:\Projects\2017\71730 Old Durham Wood\SWPPP\ODW SWPPP October 2019.doc
Hydraulic Woodsplitters
Used for splitting firewood rounds into pieces that can be wrapped into firewood
bundles or sold as bulk firewood.
3.3.2 Hazardous Materials
Hazardous materials that are currently onsite, and proposed to be added to the facility, consist of
the following:
Diesel fuel
Diesel fuel is currently stored in a 500-gallon trap wagon to fuel equipment used at the
facility. Eventually, a 10,000-gallon tank will be used for red diesel and a 10,000-gallon
tank for on-road diesel.
Gasoline
Gasoline that is used for the wood splitter engines is currently stored in a 500-gallon
aboveground tank located near the existing metal building. The proposed expansion
includes construction of a 1,000-gallon aboveground tank that will replace the existing
500-gallon tank.
Hydraulic Oil
Hydraulic oil is currently kept in 5-gallon buckets inside the metal building, which is used
in the wood splitters.
Engine Oil
Used engine oil is currently kept in 5-gallon buckets inside the metal building prior to
being transported to the owner’s property at 8616 Durnel Drive to be added to the waste
oil container. New engine oil is kept in 5-gallon buckets that are kept inside the metal
building, which is used for the wood splitters.
3.4 Storm Drainage System
Discharge from the property historically occurred from a pond located in the southwest corner
of the facility. Site stormwater will continue to be collected in this location of the site and
pumped through a series of rice checks prior to discharge to Hamlin Slough. Biofiltration as a
treatment method has been used successfully at other wood processing sites to remove
coloration and total suspended solids from the stormwater. This treatment alternative was
discussed with Regional Water Board staff as a feasible option.
3.5 Impervious Areas
Approximately 100 percent of the site is impermeable lava cap.
3.6 Potential Areas of Soil Erosion
The majority of the facility is lava cap that has been washed and paved to create a level surface
and is not subject to soil erosion.

4.0 SOURCE IDENTIFICATION
This section includes the identification of various sources of pollutants.
4.1 Industrial Activities
Industrial activities will include the receiving and processing of wood and chips.
4.2 Material Handling and Storage Areas
Hazardous materials from operations are stored onsite in a containment area which includes the
appropriate containment BMPs.
4.3 Dust- and Particulate-Generating Activities
Dust and particulate matter can be generated from onsite activities.
4.4 Non-Stormwater Discharges
There are no regular or planned non-stormwater discharges for the facility.
4.5 Fuel and Oil Containment Area and Maintenance Area
Potential sources for pollution on the site are fuels and oils used in machinery and heavy
equipment. All trucks will be subcontracted and fueled offsite. Diesel fuel for onsite equipment
is stored in a fuel storage tank near the center of the site. Vehicles and equipment used in the
operation will be maintained to prevent any possible leaks. Routine onsite maintenance will be
conducted in such a manner as to minimize the potential for leaks and spills. Major repairs,
other than emergency repairs, will be conducted at an offsite facility.
4.6 Potential Spill Locations
The loading area and fueling area are the locations in which spills are most likely to occur.
Potential spills are unlikely to come into contact with stormwater, as fueling will be performed
intermittently and under supervision.
4.7 Spills of Significant Materials
No spills of significant materials have occurred on the site.

5.3 Existing Data on Quality of Stormwater from the Site
Historical stormwater quality data for the site is summarized in Table 5-2.
At the request of the RWQCB, ODW conducted stormwater sampling during the 2018-2019
winter season. Analytical parameters of biochemical oxygen demand (BOD, average 54 mg/L),
nitrate N (average 1.06 mg/L), and total suspended solids (TSS, 298 mg/L) exceeded Numeric
Action Level (NAL) values. Nitrate results, however, did not use the SWRCB-specified method
and will be sampled during the first storm episode. In addition, copper concentrations were
elevated; however, these concentrations were within NAL limits after adjusting for hardness.

6.0 STEPS TO REDUCE POLLUTION FROM STORMWATER RUNOFF
This section summarizes the BMPs that are to be implemented at the facility to reduce or limit
stormwater pollution from the site. As stated in the regulations, priority will be given those
BMPs that control pollution with low or modest cost. Source control and treatment control
BMPs will be considered if operational BMPs do not prove to be effective. Copies of standard
industry BMP description sheets are included in Appendix A. Required minimum BMPs from
the new Industrial General Permit (NPDES No. CAS000001, 2014-0057-DWQ) are discussed in
the following sections.
6.1 Stormwater Management Controls
The site is generally flat. Stormwater controls will consist of the following:
6.1.1 Good Housekeeping
Good housekeeping requires the maintenance of clean, orderly facility areas that discharge
stormwater. Material handling areas will be inspected and cleaned to reduce the potential for
pollutants to enter the stormwater conveyance system. Trash and refuse will be placed in
appropriate containers onsite. Trash bin lids will be closed.
To prevent organic debris from entering stormwater drainage, sweeping of the paved portion of
the facility will be performed daily. Organic material from handling and processing of wood
materials will be scraped daily and placed in piles. Wattles will be placed and maintained around
all organic piles, including those in the initial vacating area and the unloading and storage area.
Waste wood/organic material will be transported offsite to cogeneration facilities for use as
landscape bark or for composting.
Source control BMPs from the California Stormwater Quality Association used to control and
prevent stormwater impacts include:
EC-9 Earth Dikes and Drainage Swales
SC-10 Non-Stormwater Discharges
SC-11 Spill Prevention, Control, and Cleanup
SC-20 Vehicle and Equipment Fueling
SC-21 Vehicle and Equipment Cleaning
SC-22 Vehicle and Equipment Repair
SC-30 Outdoor Loading and Unloading
SC-31 Outdoor Liquid Container Storage (portions of)
SC-32 Outdoor Equipment Operations
SC-33 Outdoor Storage of Raw Materials
SC-34 Waste Handling and Disposal
SC-35 Safer Alternative Products
SC-41 Building and Grounds Maintenance
SC-43 Parking/Storage Area Maintenance
SC-44 Drainage System Maintenance
October 2019 Page 13
P:\Projects\2017\71730 Old Durham Wood\SWPPP\ODW SWPPP October 2019.doc
6.1.2 Preventive Maintenance
This practice includes inspection and maintenance of the stormwater conveyance system.
Inspections will take place monthly and after significant rainfall events. An annual inspection of
the site will be conducted in September of each year to identify and address any potential issues.
6.1.3 Spill Prevention and Response
This includes increasing employee awareness toward minimizing spills and the training to
respond to spills if they occur (BMP SC-11). Each employee will be directed to clean up spills as
they occur and to report any spills of significant quantity.
6.1.4 Material Handling and Storage
This includes training employees on the proper way to handle the materials to minimize the
potential for spills and to minimize the exposure of materials to stormwater. BMPs include SC-
30, SC-31, SC-32, SC-33, and SC-34.
6.1.5 Waste Handling and Recycling
Employee training will include how to handle wastes that may occur in connection with future
activities onsite (BMP SC-34).
6.1.6 Stormwater Management Practices
Stormwater runoff generally flows in an easterly direction at the facility. Figure 2 shows the
direction of stormwater runoff. Runoff will be directed to prevent comingling with other areas
by berms and ditches (BMP EC-9).
6.1.7 Erosion and Sediment Control
The majority of the facility is paved, minimizing the potential for erosion. Vehicle traffic is
limited on the unpaved portions of the property during precipitation events to prevent erosion.
6.1.8 Dust- and Particulate-Generating Activities
Dust may be generated by truck traffic and particulates may be generated by handling and
processing woody materials onsite. The AQMD will manage the requirements for the dust- and
particulate-generating activities as discussed in Section 4.
6.1.9 Non-Stormwater Discharges
No non-stormwater discharges are associated with the facility. BMPs include SC-10, SC-21, and

6.1.10 Discharge Prohibitions
The discharge of wastewater at a location or in a manner different from that described is
prohibited. The discharge of sediment or any other waste to surface waters or surface water
drainage courses is prohibited. Discharge of hazardous or toxic substances, including petroleum
fuel, is prohibited. Bypass or overflow of untreated or partially treated waste, including domestic
waste, is prohibited.
6.1.11 Employee Training
Employee training programs will inform all personnel responsible for implementing the SWPPP.
Training will address spill response, good housekeeping, material management practices,
inspections, maintenance, and repair measures. Training will be performed for each new hire
and on an annual review basis, usually prior to the wet season.
6.1.12 Inspections
All inspections, visual observations, and sampling, as required in the Monitoring and Reporting
Program, will be completed by trained personnel.
6.1.13 Recordkeeping and Internal Reporting
Records of all inspections, spills, and maintenance activities will be kept onsite at the office.
These are available to personnel as necessary.
6.1.14 Quality Assurance
The procedures contained in the SWPPP will be conducted under the direction of Mr. Randy
McLaughlin.
6.2 Structural BMPs
BMPs for this facility are summarized in Table 6-1 and described below. The BMPs are tailored
to the activities and conditions at the project site. Facility operators are required to develop and
implement additional BMPs as appropriate and necessary to prevent or reduce pollutants.
6.2.1 Log/Wattle Barriers and Berms
Log/wattle barriers and berms are used onsite along the northern boundary to prevent run-on
and direct stormwater onsite to the sample point. If needed, logs and wattles can be placed in
additional locations onsite to slow flow velocity and capture/direct onsite flow and sediment.
Logs can be used collectively with wattles to prevent sediment and organic fines. Wattles will be
placed on the upstream side of the logs.
6.2.2 Rice Check Filter System
Old Durham will use the historical rice fields as a biofilter to filter stormwater prior to discharge
to Hamlin Slough.

6.2.3 Organic Matter Control
Because of the organic matter that can be generated onsite, source control and reduction are
critical. Measures to reduce organic matter may include:
Remove organic matter from the facility as soon as possible
Contain organic matter in identified areas with a log or straw bale perimeter
Scrape accumulated debris daily
Place additional wattles in areas of organic matter accumulation if rain is predicted
6.3 Proposed Additional BMPs
The site will collect water in a central location in the southwest area of the site and gravity-feed
or pump collected stormwater through a grassland filter system on the southern parcel. The
historical rice checks will provide retention time to settle any solids and the grass will filter
additional organic material. ODW is currently rebuilding the rice checks to work as originally
designed. Once completed, the discharge location map will be updated.

7.0 MONITORING PLAN
7.1 Checking BMP Implementation
Personnel responsible for implementation of the SWPPP will conduct inspections of the facility
operations to ensure that BMPs are implemented and meet the objectives of the SWPPP.
Inspections will be conducted monthly and during storm events (as required by Section
XI.A.1.a).
7.2 Effluent/Stormwater Monitoring (Discharge)
Visual inspections will document the presence of any discoloration, stains, odors, floating
materials, etc., as well as the source of any discharges. Stormwater runoff from the industrial
area will discharge at one location as shown on Figure 2.
Facilities classified as SIC 2411 are required to collect samples for TSS, pH, and total petroleum
hydrocarbons – oil and grease (TPH-O&G). Based on analytical results from 2019 sampling,
ODW will also sample for BOD and nitrate + nitrite nitrogen. Sampling parameters, test
methods, annual Numeric Action Levels (NALs), and instantaneous NALs are shown in
Table 7-1. Samples must be received by the laboratory within 24 hours of collection.

7.3 Sampling Procedures
Sampling and sample preservation procedures are conducted in accordance with the current
edition of Standard Methods for the Examination of Water and Wastewater by the American Public
Health Association, per SWRCB 2014-0057-DWQ and 40 CFR Part 136. Additional guidance
on sampling procedures can be found in the U.S. EPA Industrial Stormwater Monitoring and
Sampling Guide included as Appendix C.

Table 7-2
MONITORING AND SAMPLING REQUIREMENTS
Monitoring Description
Annual Evaluation
A comprehensive site inspection will be performed once during the reporting period (July
1 to June 30). The evaluation will include an inspection of BMPs, stormwater conveyance
systems and areas of industrial activity as well as an assessment of the effectiveness of all
BMPs and a review of all previous inspections during the reporting year.
Monthly Visual
Inspections
Visual observations will be made during daylight hours with no storm discharges, during
scheduled hours of operation.
Sampling Event
Visual
Observations
Four storm events that occur during normal hours of observations and proceeded by at
least two days without stormwater discharges include a visual inspection (two between July
1 and December 31 and two between January 1 and June 30). The inspection occurs at
the same time sampling occurs at a discharge location. At each discharge location where a
sample is obtained, the Discharger shall observe the discharge of stormwater associated
with the industrial activity. The Discharger shall visually observe and record the presence
or absence of floating and suspended materials, oil and grease, discolorations, turbidity,
odors, trash/debris, and sources of any discharged pollutants.
Sampling
Stormwater samples are collected at the monitoring point identified on Figure 2. Four
samples are collected annually, two between July 1 and December 31 and two between
January 1 and June 30. A qualifying storm event is a storm that produces a discharge for
at least one drainage area and is preceded by 48 hours with no discharge from any drainage
area.
Samples are analyzed for:
Total Suspended Solids (TSS) –SM 2540-D
pH – EPA9040 and/or calibrated pH meter
Total Petroleum Hydrocarbons – Oil & Grease (TPH-O&G) – EPA 1664
BOD – SM 5210B
Nitrate + Nitrite Nitrogen – SM 4500-N03E
Sampling preparation is essential due to infrequent measureable storm events. Laboratory-
supplied sample bottles should be obtained well ahead of time and weather forecasts monitored
for predicted measurable storm events.
A list of the sample bottles required for each sampling and to be stored onsite is included in
Table 7-3. No bottle is included for pH, which will be measured in the field. Sample bottles
should be labeled using waterproof ink with the following information:
Facility name and address
Sample location identifier (e.g., Location SP-1)
Name or initials of sampling personnel
Parameter(s) sample being analyzed
Sample preservation notes
Date and time of sampling event
A chain-of-custody form will also be filled out completely for samples collected.

1 = Number of bottles listed is for each discharge location; two to three times the quantity listed is necessary to conduct sampling facility-wide.
Sampling supplies should be maintained onsite at all times. Supplies include sample bottles
(including spare bottles), visual monitoring form (included as Form B in Appendix B), clipboard,
sampling pole, disposable nitrile gloves, waterproof pens, waterproof clothing, sample cooler,
field multi-parameter probe, and camera.
Sampling supplies should be stored in sealed coolers in an area with no exposure to possible
contaminants, including sediments or oil and grease.
Sample collection will be conducted in such a way as to ensure samples are representative of the
quality and quantity of the facility’s stormwater discharge. Samples will be collected directly into
laboratory-supplied sample bottles using disposable nitrile gloves.
Sample bottles should be filled directly from the discharge; never collected in a container first
and then transferred to the sample bottle. Samples should be collected from a turbulent section
in the central part of the flow. The sampler should avoid touching the bottom or sides of the
stormwater conveyance.
Immediately following collection, samples will be placed directly into laboratory-supplied
coolers, on ice, and transferred to a California-certified analytical laboratory.
Monitoring instruments used to measure pH and specific conductance are calibrated and
maintained in accordance with manufacturers’ specifications to ensure accuracy.
A probe similar to Hanna Instruments HI 98129 can be used for pH measurements. The meter
should be calibrated as outlined in the instruction manual immediately prior to each sample
collection. When not in use, the probe should be kept moist with electrode storage solution.
Additional information on operation, calibration, and maintenance of the HI 98129 probe is
included as Appendix D.
Laboratory analyses are conducted according to the test procedures described in 40 CFR Part
136 by a laboratory certified for the required analyses by the State Department of Health
Services.

7.4 Inspections
In addition to the maintenance inspection schedule described herein, supplemental inspections
of the facility related to the control of pollutants in stormwater discharge may be required.
7.4.1 Monthly Non-Stormwater Inspections
Routine facility inspections and comprehensive site inspections are conducted by a
representative designated by the facility owner/operator. In addition, the facility manager may
assist with these inspections as needed. See Form A in Appendix B.
Routine facility inspections are conducted once per month during daylight hours of scheduled
facility operating hours and on days without precipitation. Monthly inspections include
observations for:
The presence or indications of prior, current, or potential unauthorized non-stormwater
discharges and their sources;
Authorized non-stormwater discharges and associated BMPs;
Outdoor industrial equipment and storage areas, outdoor industrial activities areas,
BMPs, and other potential sources of industrial pollutants.
7.4.2 Sampling Event Visual Observations
Sampling event visual observations are conducted at the same time sampling occurs at a
discharge location. A qualifying storm event is one that produces stormwater discharge during
daylight-scheduled facility operating hours and is preceded by at least two working days without
stormwater discharge as specified in SWRCB 2014-0057-DWQ. See Form B in Appendix B.
The presence or absence of suspended materials, oil and grease, discolorations, turbidity, and
odors, and the source of any observed pollutants will be documented.
7.4.3 Annual Comprehensive Facility Evaluation
Comprehensive facility inspections will be performed at least once every stormwater reporting
period (July 1 through June 30; see Form C in Appendix B). Comprehensive annual facility
inspections will involve inspection of the entire facility for stormwater damage and adequacy of
control features for evidence of or potential for pollutants entering the drainage system during a
rain event. A visual inspection of all equipment needed to implement the SWPPP will be
included. It is recommended that this inspection occur before the first storm of the year.
7.5 Reporting
Annual reports will be submitted via the SMARTS system no later than July 15th following each
reporting year using the standardized format and checklists in SMARTS. Annual reports will
include the following:
October 2019 Page 20
