What is a Geographic Response Plan?

A Geographic Response Plan (GRP) is a planning document and response tool that is intended to guide local responders in the first 24-48 hours of a major coastal oil spill until additional resources supplied by Unified Command can arrive. As a response tool the GRP allows quick decisions to be made by providing detailed geographic information on shoreline types, sensitive natural and cultural resources. This information, together with estimates of response equipment requirements, staging locations and pre-identified deployment strategies for protecting sensitive environmental areas, provides a basis for local responder to develop a more effective and coordinated initial response. A Geographic Response Plan (GRP) is usually part of the Area Contingency Plan (ACP) that each USCG Sector is required to maintain to enhance preparedness and prevention activities for all coastal areas of the United States.

The Massachusetts Department of Environmental Protection has contracted with Nuka Research and Planning Group to prepare GRP's for all coastal areas. Preparation and funding of these response plans will be a major focus of MassDEP's efforts in meeting the oil spill response and preparedness mandates of the Mass. Oil Spill Act.
