USEPA Outlines Amendments to Oil & Hazardous Substances Pollution Contingency Plan

USEPAThe U.S. Environmental Protection Agency (USEPA) wants to amend requirements under the National Oil and Hazardous Substances Pollution Contingency Plan (NCP) to improve the nation’s ability to plan for and respond to oil spills. The USEPA says its proposal comes in response to the issues raised by the public, responders, government, and industry officials during the 2010 Deepwater Horizon Oil Spill. "Our proposed amendments incorporate scientific advances and lessons learned from the application of spill-mitigating substances in response to oil discharges and will help ensure that the emergency planners and responders are well-equipped to protect human health and the environment," says Mathy Stanislaus, USEPA Office of Solid Waste and Emergency Response Assistant Administrator.

Proposed amendments to Subpart J of the NCP include:

  • New and revised product toxicity and efficacy test methodologies for dispersants, and other chemical and biological agents.
  • New toxicity and efficacy criteria for listing agents on the Subpart J Product Schedule.
  • Additional human health and safety information requirements from manufacturers.
  • Revised area planning requirements for chemical and biological agent use authorization.
  • New dispersant monitoring requirements when used on certain oil discharges.
  • New aquatic toxicity thresholds such that products that meet both the performance and toxicity criteria will offer greater performance at less environmental impact.
  • Product chemical ingredient disclosure options, new evaluation criteria, and a process for removing products from the Product Schedule.

Comments about the proposed changes can be shared via the Federal Register. The comment period closes on April 22, 2015.
