Earlier this week, Judge Mary Lisi, of the District Court of Rhode Island, dismissed the Conservation Law Foundation’s Residual Designation Authority law suit against EPA.  CLF had asked the Court to order EPA to require permits from stormwater dischargers alleged by CLF to be contributing to exceedances of the Total Maximum Daily Load established by Rhode Island for certain impaired water bodies. 

CLF alleged that EPA’s approval of the TMDLs constituted a determination that certain stormwater dischargers were contributing to exceedances of water quality criteria and that the controls on these dischargers are necessary to meet the TMDL and thus attain the water quality criteria.… More

At least since the Standells’ Dirty Water in 1966, cleaning up the Charles River has been on the mind of Bostonians (and Cantabrigians and those farther upriver).  Notwithstanding significant recent progress, there remains work to do.  The questions are, as always, how much and who pays?  Is this largely a municipal infrastructure problem?  Is it just a matter of better implementation of some simple best management practices? … More

In February, we noted that the Conservation Law Foundation and the Charles River Watershed Association had threatened to sue EPA for failing to require that “commercial, industrial, institutional, and high density residential property dischargers of nutrient-polluted stormwater” obtain NPDES permits, and for failing to make a final determination on CLF’s and CRWA’s petition that EPA exercise its residual designation authority with respect to stormwater discharges in the Charles River Watershed.  … More

In 2008, EPA made a preliminary determination to use its residual designation authority (RDA) under the Clean Water Act to designate stormwater discharges from two or more acres of impervious surfaces in the Lower Charles River Watershed and released a draft general permit to cover such discharges.  However, EPA never finalized that designation.

In 2013, the Conservation Law Foundation and other groups petitioned EPA Regions 1,… More

Stormwater regulation is a thorny issue.  There is widespread agreement that nutrient run-off can be a significant problem, but little agreement on what to do about it, since stormwater infrastructure is normally managed by cash-strapped municipalities, but the most cost-effective approach will often not be to require thousands of individual properties owners to make large separate capital expenditures (though best management practices can certainly often provide significant benefit).

The NRDC,… More
