Federal Government and Stormwater Fees

  • Federal Government Obligations to Pay Stormwater Fees — On January 4, 2011, President Obama signed into law "An Act to Amend the Federal Water Pollution Control Act to clarify Federal responsibility for stormwater pollution," Pub. L. No. 111-378, 124 Stat 4128 (2011) to clarify that reasonable service charges payable by federal agencies, as described in section 313(a), include certain stormwater assessments.
  • Memorandum Clarifying that New Legislation Provides for Stormwater Fees to be Paid from Current Lump-sum Appropriations — On March 18, 2011, the Department of Justice/Office of Legal Counsel released a memorandum to clarify that language in section 313(c)(2)(B) of the Clean Water Act contained in new legislation obligating federal agencies to pay stormwater managements fees does not impose a specific appropriation requirement. Stormwater assessments are payable from annual—including current—lump-sum appropriations.
