MPCA Infiltration Device - Pond Requirements

2010-02-17T12:20:00.005-06:00

The use of stormwater infiltration has been a popular choice for stormwater management for many years. The benefits of infiltration include reducing overall run-off volume, reducing stormwater and channel run-off rates, and reducing pollutant loading.

However, infiltration can also create other issues, including groundwater contamination. Infiltration of stormwater (and the wastes it carries) may also invoke other environmental regulations.

The Minnesota Pollution Control Agency has incorporated requirements for the use of both infiltration devices and stormwater ponds used to manage industrial site runoff. These requirements include:

1. Industrial stormwater ponds and infiltration devices located in areas where high levels of contaminants exist in the soil or in the shallow aquifer, must not contribute to contaminant(s) spreading to a greater extent or rate. At any contamination site, a site analysis shall be conducted and a report filed with the SWPPP.

a. If industrial stormwater ponds and infiltration devices are found to be a contributor to contaminant increase or movement, the site must submit a plan to MPCA that describes how they will be reducing contaminants, redesigning, relocating, or eliminating the industrial stormwater ponds and infiltration devices, as needed, to eliminate the contribution to contaminant problems.

2. Industrial stormwater ponds and infiltration devices can not be used in any high risk karst area unless a professional geotechnical evaluation is conducted to ensure that they do not present a significant risk to groundwater.

a. If the industrial stormwater ponds and infiltration devices present a risk, appropriate measures, such as sealing or removal of the industrial stormwater ponds or infiltration devices, must be taken to eliminate or minimize the risk. Evaluations shall be documented with the SWPPP.

3. Use of industrial stormwater ponds and infiltration devices in vulnerable wellhead protection areas must be coordinated with local drinking water authorities and shall be designed to not adversely affect drinking water supplies. The facility must contact the appropriate local drinking water authorities and document coordination efforts with the SWPPP.

4. Facilities using any infiltration device defined as a “Class V injection well” shall contact the US EPA Region HQ to determine the need to register as a “Class V injection well”. Contacts and USEPA response need be documented with the SWPPP.

MPCA Stormwater Permit Application - Due Dates By Industry Sector

2010-02-15T08:12:00.006-06:00

The Minnesota Pollution Control Agency is in the final stages of releasing a revised industrial stormwater general permit. The revised permit will replace the current permit that was issued in 1997. The revised permit represents a significant departure from compliance requirements Minnesota industrial and “industrial-like” facilities have had.

MPCA’s tentative schedule is to present findings on the revised permit to Citizens’ Board and request Board approval of permit on March 23, 2010. Assuming that the permit is approved, MPCA anticipates the final permit with be effective April 1, 2010.

All facilities subject to the stormwater rules must submit an application for coverage under the revised permit, even if already covered under the expired permit. Existing facilities must have prepared and implemented a new SWPPP and be in compliance with the new permit before they apply for permit coverage. New facilities must submit applications at least 180-days before beginning construction or operation.

Because of the volume of applications that MPCA expects to receive, the due date for applications is staggered over six months. Application due dates will be based on the industrial sector a given facility falls into:

SWPPP Employee Training - Stormwater Training Requirements FAQ

2010-02-03T08:13:00.003-06:00

Stormwater regulations and most State and EPA NPDES stormwater discharge permits require some form of EMPLOYEE SWPPP TRAINING. Below are some common questions, or FAQ, Caltha receives regarding industrial stormwater pollution prevention training.

1. What Kind of Training is Required?
The answer will depend on the State your facility is located in – different States will have different training requirements. However, Caltha generally sees three categories for training:
a) SWPPP Awareness Training. This is “high-level” training which may be given to all employees, and covers basics of stormwater program and facility controls that would apply to any employee.
b) Stormwater Training. This training would be addressing employees whose day-to-day work activities relate to the specific controls and procedures the facility has established in its SWPPP, such as dock workers who might be involved with spills.
c) Stormwater Permit Compliance Training. Employees who have been assigned specific compliance tasks, such as conducting inspections, collecting stormwater samples, need to be trained to conduct their tasks.

2. Can I Use Generic Training Materials?
Many good training resources are available, including video training and “on-line” courses. Caltha often recommends these resources as a element of a facility’s training program. Whether or not these types of “off-the-shelf” training resources meet the training requirements will depend on the specific requirements for your State. In many cases, training needs to include information on the facility SWPPP, and therefore the “off-the shelf” resources need to be augmented with facility-specific training.

3. Does Every Employee Need to be Trained?
Possibly. However, as described in #1 above, not all employees need to have the same level of training. In addition, other factors, such as ISO 14001 registration, may require that you consider training contractors working at your facility.

4. How Often Does Training Need to be Presented?
Many States require annual refresher training; however, some training might only be presented once, such as Permit Compliance Training.

5. Does Stormwater Training Need to be Documented?
Yes, because training is a requirement of an NPDES discharge permit, records need to be maintained to demonstrate that all affected employees received the appropriate training.

6. Do Our Trainers Need Special Training?
This is not addressed in most States; however, effective trainers need to understand their subject matter. Caltha offers a number of “train-the-trainer” options.

b) delivery vehicles,
c) Fuel unloading areas,
d) areas adjacent to disposal ponds and landfills.

Monthly inspections must include all residue-hauling (i.e. ash) vehicles for proper covering over the load, adequate gate sealing, and overall integrity of the container body. Dischargers must repair, as soon as practicable, vehicles without load covering or adequate gate sealing, or with leaking containers or beds.

Preventative Maintenance:
The SWPPP must describe and implement measures that prevent or minimize stormwater from contacting fugitive dust emissions from coal handling areas and to prevent or minimize contamination of stormwater runoff from delivery vehicles carrying significant materials arriving at the facility. The SWPP must have procedures ensuring overall integrity of the body or container and procedures to deal with leakage or spillage from vehicles or containers.

The SWPPP must also describe and implement measures that prevent or minimize contamination of surface runoff from oil-bearing equipment in switchyard areas and to retard flows and limit the spread of spills from oil-bearing equipment in switchyards, or collecting runoff in perimeter ditches from these areas.

Spills and Leaks:
The SWPPP must describe and implement measures to reduce the potential for an oil or chemical spill, or reference an SPCC plan, and to visually inspect the structural integrity of all above-ground tanks, pipelines, pumps, and related equipment, and conduct any necessary repairs immediately.

Management of Runoff:
The SWPPP must describe and implement measures that prevent or minimize contamination of surface runoff from areas adjacent to disposal ponds or landfills, and must include procedures to reduce ash residue that may be tracked on to access roads traveled by residue handling vehicles, and reduce ash residue on exit roads leading into and out of residue handling areas.

SWPPP Contents:
The SWPPP must identify:
1) scrap yards, and general refuse areas;
2) short- and long-term storage of construction materials, paint equipment, oils, fuels, used and unused solvents, cleaning materials, paint, water treatment chemicals, fertilizer, and pesticides);
3) landfills and construction sites; and
4) stockpile areas (e.g., coal or limestone piles).

Stormwater Monitoring Benchmarks:

Arizona ADEQ Draft Industrial Multi Sector General Stormwater Permit

2010-02-01T19:28:00.005-06:00

The Arizona Department of Environmental Quality (ADEQ) recently posted an updated draft of its proposed multisector industrial stormwater discharge general permit for informal stakeholder review and input. This permit “AZPDES MSGP 2010”, once promulgated, will replace the existing industrial stormwater permit, which expired in 2005. ADEQ anticipates the MSGP to be public noticed sometime during the winter of 2010.

The AZPDES MSGP 2010 contains 8 parts and 5 appendices. Parts 1 through 7 describe the requirements that all operators must meet when seeking coverage under this permit. Part 8 describes the additional sector-specific requirements for industrial activities, sub-divided into 30 industry sectors.

Much of the ADEQ permit is based on the US EPA Multi-Sector General Permit (MSGP 2008) that became effective on Sept. 29, 2008. Some of the Arizona-specific changes from the MSGP 2008 include:

The NOI must include the well registration number if stormwater associated with industrial activity is discharged to a dry well or an injection well.
Facilities with liquid storage areas for SARA Section 313 water priority chemicals must be operated to minimize discharges of such chemicals.
All facilities or any portion of a facility that is located at or within the 100-year floodplain must be delineated on the site map.
Facilities subject to monitoring and reporting requirements must submit a discharge monitoring report form(s) and other required monitoring information.
The term "significant sources of non-stormwater" includes, but is not limited to, discharges that could cause or contribute to violations of Arizona water quality standards, and discharges that could include releases of oil or hazardous substances in excess of reportable quantities under section 311 of the Clean Water Act (CWA) (See 40 CFR 110.10 and 40 CFR 117.21) or section 102 of CERCLA (See 40 CFR 302.4).

All facilities covered under the permit will need to comply with Parts 1 through 7. Some of the key requirements that all permittees will meet include:

SWPPP.
Each site will need to prepare and maintain a stormwater pollution prevention plan (SWPPP). The SWPPP will need to include:

Good Housekeeping.
Maintenance.
Spill Prevention and Response Procedures.
Erosion and Sediment Controls.
Management of Runoff
Management of Salt Storage Piles or Piles Containing Salt.
Sector Specific Control Measures.
Employee Training.
Elimination of Non-Stormwater Discharges.
Litter, Garbage and Floatable Debris
Dust Generation and Vehicle Tracking of Industrial Materials.

Routine Facility Inspection Procedures.
Every site will conduct routine quarterly inspections of all areas of the facility where industrial
materials or activities are exposed to stormwater with the potential to discharge from the facility, and of all stormwater control measures used to comply with this permit.

Visual Assessment of Stormwater Discharges.
Every site will also perform two visual assessments during the summer wet season and two during the winter wet season when the facility is discharging. The visual assessment is be made collecting a sample in a clean, clear glass, or plastic container, and examining it in a well-lit area.

Comprehensive Facility Inspection.
Once each year the qualified person or persons will conduct an annual comprehensive facility inspection (CFSI). A member of the facility’s stormwater pollution prevention team must conduct or participate in the inspection.

Washington Mandatory BMP and Industrial Stormwater Requirements

2010-01-04T07:07:00.004-06:00

The revised Washington Department of Ecology industrial stormwater general permit became effective on January 1, 2010. The revised permit has numerous substantive changes compared to the previous industrial stormwater permit. Some highlights of these changes include:

Stormwater Pollution Prevention Plan (SWPPP) Requirements

Mandatory BMPs must be implemented no later than July 1, 2010. The facility may omit individual BMPs if site conditions render the BMP unnecessary, infeasible, or the Permittee provides alternative and equally effective BMPs; and justifies the omission in the SWPPP. The mandatory BMPs include:

Operational Source Control BMPs:

Vacuum paved surfaces with a vacuum sweeper once each quarter.
Minimize stormwater contamination from dust. Inspect and maintain bag houses monthly.
Keep all dumpsters under cover or keep dumpster lid closed when not in use.
Clean catch basins when at capacity.
Inspect all equipment and vehicles for leaking fluids. Take leaking equipment and vehicles out of service or prevent leaks until repaired.
Store all chemical liquids, fluids, and petroleum products on an impervious surface with containment that is capable of containing 10% of the total enclosed tank volume or 110% of the volume contained in the largest tank, whichever is greater.
Prevent precipitation from accumulating in containment areas.
Locate spill kits within 25 feet of all stationary fueling stations, fuel transfer stations, and mobile fueling units.
Facility personnel can not lock shut-off fueling nozzles in the open position, or “top-off” tanks being refueled.
During fueling, facility personnel must block, plug or cover storm drains that receive runoff from areas where fueling.
Use drip pans or equivalent containment measures during all petroleum transfer operations.
Maintain a spill log that documents chemical and petroleum spills.

Structural Source Control BMPs:

Use grading, berming, or curbing to prevent runoff of contaminated stormwater flows and divert run-on away from manufacturing, processing, and material storage areas.
Perform all cleaning operations indoors, under cover, or in bermed areas that prevent stormwater runoff and run-on and capture any overspray. Drain wash water to a collection system for further treatment or storage.

SWPPP Signature/Certification

The Permittee must sign and certify the SWPPP and any revisions.

Benchmark Monitoring / Sampling

Facility must sample each distinct point of discharge off-site each calendar quarter; except “substantially identical outfalls”. Sampling must occur within the first 12 hours of stormwater discharge or as soon as practicable after the first 12 hours. Facilies must sample the stormwater discharge from the first fall storm event, after October 1st. “Consistent attainment” requires that four consecutive quarterly samples be equal to or less than the benchmark value; or for pH, within the range of 5.0 – 9.0.

Discharges to 303(d)-Listed Waters

Numeric effluent limits now apply to facilities with discharges to 303(d)-listed impaired waterbodies (Category 5).

Inspections

Qualified personnel conduct and document visual inspections of the site monthly. Dry season and annual comprehensive inspection eliminated.

Corrective Actions

Permittees that exceed benchmark value (for a single parameter) for any two quarters during a calendar year complete a Level 2 Corrective Action (Structural Source Control BMPs). Permittees that exceed benchmark value (for a single parameter) for any three quarters during a calendar year complete a Level 3 Corrective Action (Treatment BMPs).

Facilities must revise their SWPPP and complete installation by September 30th the following year. All corrective actions must be documented in Annual Report. A licensed professional engineer, geologist, hydrogeologist, or certified professional in storm water quality (CPSWQ) must design and stamp the portion of the SWPPP that addresses (Level 3) stormwater treatment structures or processes.

Wisconsin Requirements for Contaminated Sediment Management

2010-01-04T07:01:00.002-06:00

The Wisconsin Department of Natural Resources (WDNR) has promulgated rules regulating the beneficial reuse of sediment removed from stormwater detention ponds (Chapter NR 528). These rules streamline the assessment and approval process for the reuse of dredged sediments, especially if not intended to be disposed of in a landfill.

WDNR rules establish management standards, risk assessment procedures and “ceiling” contaminant concentrations for sediments. The sediment contaminants regulated under NR 528 include several heavy metals (arsenic, cadmium, chromium, lead), pH and electrical conductivity.

The end-uses considered under the rule include:

Disposal in licensed landfill,
General fill,
Confined geotechnical fill,
Landspreading,
Dedicated sediment management sites, and
Small quantity, course grained sediment management

NR 528 defines the level of risk assessment, acceptance criteria and specific management practices required for the different end-uses. The designated sediment manager must assure that these requirements are met and provide the required documentation and reporting.

Technical Guidance For EISA Section 438 Compliance

2009-12-14T09:45:00.003-06:00

Under the new Section 438 of the Energy Independence and Security Act of 2007 (EISA), federal agencies have new requirements to reduce stormwater runoff from federal development and redevelopment projects to protect water resources. Federal agencies can comply using a variety of stormwater management practices often referred to as "green infrastructure" or "low impact development" practices, including for example, reducing impervious surfaces, using vegetative practices, porous pavements, cisterns and green roofs.

US EPA has recently issued guidance ("Technical Guidance on Implementing the Stormwater Runoff Requirements for Federal Projects under Section 438 of the Energy Independence and Security Act") to assist federal agencies in minimizing the impact of federal development projects on nearby water bodies. The guidance is being issued in response to a change in law and an Executive Order signed by President Obama, which calls upon all federal agencies to lead by example to address a wide range of environmental issues, including stormwater runoff.

The purpose of the guidance document is to provide technical guidance and background information to assist federal agencies in implementing EISA Section 438. Each agency or department is responsible for ensuring compliance with EISA Section 438. The document contains guidance on how compliance with Section 438 can be achieved, measured and evaluated.

EPA Extends 2008 Construction Stormwater Permit

2009-12-10T19:49:00.003-06:00

US EPA has proposed to extend the 2-year term of the Agency’s July 2008 general permit for stormwater discharges from construction activities (CGP) by 1 year. According to EPA, the extension is needed to ensure Agency compliance with a court order requiring promulgation of effluent limitations guidelines (ELG) and new source performance standards (NSPS) for the construction and development (C&D) point source category.

The 2008 CGP provides coverage for discharges from construction sites in areas not addressed by an approved state national pollutant discharge elimination system (NPDES) program. EPA Regions 1, 2, 3, 5, 6, 7, 8, 9, and 10 issued the 2008 CGP to replace the expired 2003 CGP for operators of new and unpermitted ongoing construction projects. The current 2008 CGP expires on June 30, 2010.

EPA is proposing to extend coverage of the CGP to June 30, 2011. This would give EPA approximately the same time period—18 months—that the Agency required to issue the 2003 CGP. The 2008 CGP required 3 years to finalize.
