Building a Better Construction Stormwater Permit

September 9th, 2022

Eight years after the 2009 permit expired, the State Water Board has finally adopted a new statewide Construction Stormwater Permit. This permit will require construction sites to prevent stormwater from washing sediment, nutrients, metals, and other pollutants exposed on their sites into California’s waterways. The Construction Permit has become an important environmental battleground because, although it is set to expire after five years, like its predecessor this permit will likely control pollution at construction sites well after its expiration date. Since the draft was released, corporate interests have pushed for a permit that maintains the status quo and guarantees almost no consequences for polluting while California Coastkeeper Alliance has advocated for a permit that will actually protect California’s water quality and hold polluters accountable.

One of the main areas of contention is the use of action levels versus numeric limits. Action levels are toothless monitoring requirements and exceeding an action level is not a violation of the permit. These action levels allow construction sites to pollute again and again without consequence until they have finished their construction. We have been tirelessly advocating for the use of numeric limits instead, which are clear, commonsense pollution controls. The EPA has even stated that these limits “are the best way to quantifiably ensure industry compliance and to make reasonable further progress toward the [Clean Water Act] goal of eliminating pollutants into the nation’s waters.” In contrast, the regulated industry has thrown all of their political weight at the State Water Board to remove all numeric limits and replace them with action levels.

Through our advocacy, we were able to ensure that the permit contains multiple numeric limits. This is a major victory, as the Final Permit contains more numeric limits than even the EPA’s nation-wide construction permit. Unfortunately, Governor Newsom pressured the State Water Board to avoid the use of numeric limits for toxic pollutants in Los Angeles’ most disadvantaged communities, sacrificing clean water for corporate profit in a community which faces disproportionate pollution burdens.

Another important fight was the length of the regulatory transition period. This transition period lets construction sites continue to work under the outdated permit while they transition into compliance with the new one. The longer the transition period, the longer construction sites can ignore the updated and more protective requirements of the new Permit. Corporate interests relentlessly pushed for the longest transition period possible, some even shamelessly advocating for a five-year period which would have allowed these sites to continue to work under the old permit for the entire expected life of the new one. Through our advocacy, we were able to prevent an extended timeframe and we actually were able to reduce the transition period down to two years. Construction companies have already had eight years to work under an expired permit, and we cannot let the ghost of an outdated permit haunt us throughout the life of a new one.

California Coastkeeper Alliance is happy to see the updated permit finally get adopted and the expired permit finally laid to rest.  We have been engaged with this permit process since the beginning and will continue to advocate for stronger pollution controls so everyone in California can have fishable, swimmable, and drinkable waters.
