Industrial Stormwater Monitoring in Minnesota - Benchmark Monitoring

The Minnesota Pollution Control Agency has released its revised general permit for stormwater discharges from industrial sites. The most important change in the draft permit compared to the previous MPCA general permit is the requirement to sample stormwater discharges.

Flowchart of MPCA Stormwater Monitoring Requirements


All permittees, regardless of size or business sector, will collect and analyze at least four quarterly samples during Year 2 of permit coverage. These samples will be compared to “benchmark” concentrations. Depending on the results, further quarterly samples may need to be collected in Year 4 and 5, and corrective actions may be required. Additional reporting, including a “Benchmark Exceedence Report” and evaluations will be required for dischargers who continue to exceed benchmark concentrations. All sample results will be reported to MPCA.

It should be noted that some permittees will also be subject to EFFLUENT LIMITS and will have to conduct effluent limit monitoring. The schedule and requirements for effluent limit monitoring are different from Benchmark Monitoring.

Stormwater Pollution Prevention Requirements:
All facilities are required to prepare and implement a site-specific Stormwater Pollution Prevention Plan (SWPPP). The permit includes specific information required in the SWPPP, as well as areas that need to be evaluated to determine if potential pollution sources exist. The SWPPP develops a set of Best Management Practices (BMPs) to address each of the potential source areas identified during the assessment.

Click here for information on MPCA Permit SWPPP Template

Routine Inspections:
All facilities are required conduct and document inspections at least monthly. At least one of these inspections needs to be conducted during a rainfall event.

Preventive Maintenance:
All facilities are required to prepare a Preventive Maintenance schedules for stormwater BMPs used by the site. In addition, each site will have to prepare a written equipment preventive maintenance program, including regular inspection, maintenance, and repair of industrial equipment and systems to identify conditions that could cause breakdowns or failures that may result in leaks, spills, and other releases.

Elimination of Non-stormwater Discharges:
Any facility covered under the MSGP must evaluate the potential of non-stormwater discharges from the site and to either eliminate the discharge or obtain a separate permit to discharge.

Spill Prevention and Response Procedures:
All sites must evaluate risks for spills and develop a Spill Prevention and Response procedure. This requirement applied to all facilities, and not limited to those already required to have equivalent procedures under SPCC Rules (40 CFR 112) or the Minnesota Spill Bill.

Mercury Minimization Plan:
All sites must document an evaluation of the facility to determine if any sources containing mercury are exposed to stormwater. If potential mercury sources or devices are found to be exposed to stormwater, a Mercury Minimization Plan must be developed.

MPCA Infiltration Device - Pond Requirements

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

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.

Note: Facilities that have previously submitted a No Exposure Certification need to reassess their site based on current MPCA certification requirements and reapply for coverage.

SWPPP Employee Training - Stormwater Training Requirements FAQ

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.

Arizona ADEQ Draft Industrial Multi Sector General Stormwater Permit

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:
