Jon-Erik Magnus Authors Daily Journal Article on New Los Angeles Storm Water Permit

News
August 17, 2026

Rogers Joseph O’Donnell shareholder Jon-Erik W. Magnus wrote an article for the Daily Journal examining a new regional storm water permit that significantly expands compliance obligations for commercial, industrial and institutional properties in Los Angeles County.

The article addresses the Commercial, Industrial, and Institutional (CII) Permit, adopted July 23 by the Los Angeles Regional Water Quality Control Board. The permit extends storm water sampling, reporting and, in some cases, abatement requirements to shopping centers, warehouses, hospitals and office complexes within the Dominguez Channel/Los Angeles and Long Beach Inner Harbor Watershed and the Los Cerritos Channel/Alamitos Bay Watershed. These properties were previously unregulated or exempt under prior permitting schemes.

Magnus details the permit’s scope and key compliance deadlines, including an Oct. 31, 2026 filing requirement and an April 30, 2027 sampling deadline. He also walks through the three compliance pathways available to affected facility operators:

  • Funding a local watershed improvement project
  • Implementing on-site improvements to eliminate storm water runoff
  • Directly demonstrating through monitoring that discharges meet regulatory limits

In the article, Magnus notes that failure to comply can result in mandatory minimum penalties of $3,000 per violation under California’s Water Code, in addition to potential citizen suit exposure under the Clean Water Act.

Magnus represents a wide range of clients, from Fortune 500 companies to family-owned businesses, in environmental and regulatory matters throughout California and Washington, including litigation, agency negotiations and administrative proceedings. His practice covers claims arising under CERCLA, RCRA, the Clean Water Act, and California and Washington’s state environmental statutes, along with regulatory counseling on storm water compliance, waste management and air quality rules. He regularly works with California’s Regional Water Quality Boards and the State Water Resources Control Board on cleanup directives and negotiated work scopes.
