SPCC Rule Extension For Agricultural Facilities

EPA has extended the date that agricultural facilities must come into compliance with the new Spill Prevention, Control, and Countermeasure (SPCC) rule to May 10, 2013. Agricultural facilities that began storing oil before August 16, 2002 must revise their SPCC plan to meet the 2002 changes by the May 2013 deadline.

There are several exemptions for agricultural operations. These include: milk and milk product containers, associated piping, and appurtenances; home heating oil tanks at single family homes; pesticide containers used to mix and load formulations; and pesticide application equipment.

The recent Rule changes also allow agricultural operations that store 10,000 gallons of oil or less and meet the Tier 1 or 2 qualified facility requirements to prepare and self-certify their SPCC Plan. Although anyone can use the templates, not all states allow self-certification For example, New Hampshire requires all SPCC Plans to be certified by a professional engineer.

MPCA Reports Low Compliance Rates With New Industrial Stormwater Permit

In 2010, the Minnesota Pollution Control Agency (MPCA) finalized a new industrial stormwater discharge general permit. The new permit had numerous new requirements that facilities are required to meet. One of the most significant changes was that facilities are now required to collect samples of their stormwater discharge, send the samples to a laboratory for testing, and to report the results to MPCA on a Stormwater Monitoring Report Form (SWMR).

[Read a summary of MPCA industrial stormwater monitoring requirements]

[Read a summary of the revised MPCA permit]

According to information now being circulated by MPCA, as of November 2011, about 50% of all permitted facilities in Minnesota that are required to collect a sample and submit results had failed to do so. In addition, another 25% are missing results/data on a previously-submitted SWMR. In summary, according to MPCA, only about 25% of permitted facilities were in compliance with stormwater monitoring requirements of the general permit.

MPCA indicated that it is currently considering options it can take to improve compliance rates with industrial stormwater discharge permit.

Final Washington DC MS4 Stormwater Discharge Permit

US EPA has released the final stormwater discharge permit for the Washington DC area municipal separate storm sewer system (“Washington DC MS4 Permit”). The Washington DC MS4 Permit included a number of performance-based requirements, including:


  • Requiring a minimum of 350,000 square feet of green roofs on District properties;

  • Planting at least 4,150 trees annually and developing a green landscaping incentives program;

  • Retaining 1.2 inches of stormwater on-site from a 24-hour storm for all development projects of at least 5,000 square feet;

  • Developing a stormwater retrofit strategy, and implementing retrofits over 18 million square feet of drainage of impervious surfaces;

  • Developing consolidated implementation plans for restoring the impaired waterways of the Anacostia and Potomac Rivers, Rock Creek, and the Chesapeake Bay; and

  • Preventing more than 103,000 pounds of trash annually from being discharged to the Anacostia River.

EPA believed the new permit conditions were necessary because impervious surfaces in the District, such as roads, rooftops and parking lots, channel stormwater directly into local streams and rivers. Improperly managed stormwater runoff from the District damages streams, causes significant erosion, and carries excessive pollutants like nitrogen, phosphorus, sediment, toxic metals, and solvents downstream and into the Chesapeake Bay. The permit aids the District in meeting its Chesapeake Bay pollution reduction targets and its Watershed Implementation Plan.
