Technical Terminology
Marine Corps Air Staion (MCAS) Miramar’s IR Program team works with state and federal regulatory agencies to meet or exceed cleanup requirements on base. In an effort to help educate community members in the environmental cleanup process, technical terminology and a list of acronyms used on this web site are provided. Additional information can be found on other related web sites via the Links Page provided on this site.

A list of acronyms is provided for reference purposes while using this web site. Environmental Restoration Process
The Department of the Navy (DON) Environmental Restoration (ER) process starts with identification and investigation of contaminated sites, followed by selection, design, and implementation of remedial actions to achieve remediation goals. This process is designed in accordance with CERCLA requirements.
There are two types of DON ER responses. Removal actions are taken to address releases or threatened releases requiring prompt action, while remedial actions are taken to permanently and significantly reduce the dangers associated with releases or threats of releases of hazardous substances that are serious, but not immediately life threatening. The remedial action process specifies the steps to thoroughly evaluate the nature and extent of contamination, and provides a structure to identify and evaluate cleanup alternatives.

The basic steps that are taken in a remedial action are described on the right.
Removal Action Process
In some cases, the DON and regulatory agencies may conduct a removal action of hazardous substances from a site. These removal actions are carried out in accordance with federal and state requirements. The DON can conduct a removal action if any one or more of the following criteria are present:
• An imminent threat to human health or the environment exists
• The source of the contamination can be removed quickly and effectively
• Access to contamination can be limited
• A removal action is the fastest way of remediating the site

Remedial Action Process
• PA/SI evaluates if current or past waste management practices resulted in release of hazardous substances
• RI/FS are typically performed togehter. The RI is a sampling and analysis program to determine the nature and extent of contamination. The FS is a detailed evaluation of remediation alternatives.
• PP is a fact sheet that is developed to describe cleanup alternatives and explain why the preferred alternative was chosen.
• ROD documents the selected cleanup solution, which is available for public review.
• RD/RA prepares a design for the cleanup solution along with the development of an informational fact sheet.
• Long-term Management may include LTM, which occurs at sites where hazardous substances, pollutants or contaminants remain after the RA has been completed.
• NFA takes place when all necessary remedial action activities are complete and the DON and regulatory agencies agree that no further action (NFA) is appropriate at the site. |
