Summary of Revised Industrial Stormwater Permit Requirements In Ohio

Ohio EPA has completed public comment on its proposed draft industrial multi-sector permit, and plans to issue the NPDES industrial general permit renewal in May with an effective date of June 1, 2011.

Currently, Ohio EPA plans to mail renewal notices to all permittees of the current industrial general permit (OHR000004) in mid-June. The renewal notice will include a blank NOI application form to submit to Ohio EPA within 90 days to continue general permit coverage until May 31, 2016.

The 90-day period is intended to allow permitted facilities with sufficient time to:

1. Select, design, install, and implement control measures to meet numeric and non-numeric effluent limits in the new permit;and
2. Develop a new SWPPP according to the requirements in the new permit.

OEPA Draft Industrial Permit - Storm Water Benchmark Sampling

The proposed stormwater monitoring requirements in the proposed General Permit for Storm Water Discharges Associated with Industrial Activity (Multi-Sector General Permit, or MSGP) include both effluent monitoring requirements for some facilities and benchmark monitoring requirements for most permitted facilities in Ohio. Consistent with the US EPA MSGP, the OEPA draft permit contains numeric effluent limitations based on Effluent Limitations Guidelines for Sectors A, C, D, E, J and O. [more information on difference between effluent limitations and benchmark concentrations]



The Ohio MSGP requires benchmark monitoring, specific for each industrial sector, for pollutant parameters which US EPA has determined to be of concern by industrial sector. The draft Ohio general permit requires that 19 of the 29 industrial sectors perform benchmark analytical monitoring. The benchmark monitoring requirements are not effluent limitations. Benchmark values represent a level to determine whether a facility’s SWP3 is effective.



The benchmark monitoring is based on a collection of 4 quarterly samples. If the average of the 4 monitoring values for any parameter does not exceed the benchmark value, the permittee has fulfilled their monitoring requirements for that parameter for the permit term. If this average exceeds the benchmark for a parameter, then the permittee will need to review their SWP3 and control measures and modify accordingly. Additional monitoring would be required. The US EPA MSGP’s primary source of benchmark concentrations is derived from EPA’s National Water Quality Criteria. For a majority of the benchmarks, USEPA used the acute aquatic life, fresh water ambient water quality criteria. USEPA believes these acute freshwater values best represent the highest concentrations at which typical fresh water species can survive exposures of pollutants for short durations, such as a storm discharge event.

Ohio EPA evaluated each benchmark monitoring parameter and followed US EPA’s methodology, but used Ohio Water Quality Criteria when available. As such, some US EPA benchmark values have been changed to be consistent with Ohio Water Quality Criteria. The benchmark values of some metals are dependent on water hardness. For these parameters, permittees will need to determine the hardness of the receiving water to determine the benchmark concentration that applies to their facility. Depending on the condition of the receiving water, benchmark values for heavy metals can vary widely between facilities.

Benchmarks For Metals In Ohio Industrial MSGP

The Ohio Environmental Protection Agency (OEPA) has released its draft Multi-sector General Permit (MSGP) which, once finalized, will replace the existing industrial stormwater discharge general permit, which will expire on May 31, 2011. The draft MSGP is modeled after the US EPA MSGP, released in 2008, and is significantly different compared to the existing Ohio permit.


One of the key changes is the requirement for most permitted facilities to conduct benchmark monitoring of their industrial storm water discharge. Results are compared to a list of sector-specific benchmark concentrations to determine if improvements to the stormwater pollution prevention program are needed, and whether or not further benchmark monitoring is needed.


The benchmark concentrations for each sector are listed in the permit, with several important exceptions. These are benchmarks for seven metals:





  • Beryllium



  • Cadmium



  • Copper



  • Lead



  • Nickel



  • Silver



  • Zinc



The benchmarks for these chemicals must be calculated for each individual facility based on the hardness of the receiving water, which each facility must determine. This will require individual facilities or groups of facilities to collect additional samples and do additional testing prior to starting their benchmark monitoring program.


The necessity to determine site-specific stormwater benchmarks only affects certain Ohio discharges, includes some or all facilities in fall into ten of the industrial sectors:




Sector A – Timber Products
Sector C – Chemical and Allied Products Manufacturing, and Refining
Sector F – Primary Metals
Sector G – Metal Mining
Sector K – Hazardous Waste Treatment, Storage, or Disposal Facilities
Sector M – Automobile Salvage Yards
Sector N – Scrap Recycling and Waste Recycling Facilities
Sector Q – Water Transportation Facilities
Sector Y – Rubber, Miscellaneous Plastic Products, and Miscellaneous Manufacturing Industries
Sector AA – Fabricated Metal Products

Storm Water Plan Template and Compliance Plan To Meet New OEPA General Permit

The Ohio Environmental Protection Agency (OEPA) has proposed a revised General Permit for Storm Water Discharges Associated with Industrial Activity (Multi-Sector General Permit, or MSGP. This permit will replace the existing Ohio general permit, which expires on May 31, 2011. The draft Ohio general permit is modeled after the US EPA MSGP and defines sector specific requirements for each of 29 different industrial sectors. For most facilities subject to the existing general permit, the revised MSGP will require a significant revision to the facility stormwater pollution prevention plan, or SWPPP.


To reduce the level of effort required for facilities to come into compliance with new permit requirements, Caltha LLP has prepared a SWPPP template based on Ohio permit requirements, including Ohio specific quarterly inspection checklist, quarterly visual assessment checklist, quarterly benchmark monitoring checklist, and an annual comprehensive site inspection checklist. Caltha has also prepared a Ohio Stormwater Permit Compliance Plan to assist permitted facilities in organizing and planning new compliance requirements under the OEPA general permit.

Regulation of Milk and Milk Products Under SPCC Rule

The U.S. Environmental Protection Agency (EPA) has exempted milk and milk product containers from the Oil Spill Prevention, Control and Countermeasure (SPCC) rule, potentially saving the milk and dairy industries more than $140 million per year. Based on input from the milk industry, EPA had previously delayed SPCC compliance requirements for milk and milk product containers until the mandated regulatory process could be completed. In January 2009, EPA proposed the rule to exempt milk containers from the SPCC rule. Milk production is already subject to certain construction and sanitary standards and requirements that help prevent spills.

The final exemption applies to milk, milk product containers, and milk production equipment. In addition, because some of these facilities may still have oil storage subject to the spill prevention regulations, EPA is also amending the rule to exclude milk storage capacity from a facility’s total oil storage capacity calculation. The agency is also removing the compliance date requirements for the exempted containers.

The SPCC regulations require facilities with the capacity to store more than the threshold quantity of oils and fats to create and implement plans to prepare, prevent and respond to spills. The current exemption for milk does not apply to fuel oil and other applicable oils stored on farms; farms that store above the regulatory threshold of fuel oil and other applicable oils are covered under the SPCC.

Caltha LLP provides specialized expertise to clients nationwide in the preparation and certification of SPCC Plans, development of emergency preparedness & response plans, and preparation of stormwater pollution prevention programs.
