Non-Time-Critical Removal Actions
Removal responses are common at Superfund Sites when the contamination poses an immediate threat to human health and the environment. Removals are classified as either emergency, time-critical, or non-time-critical depending on the extent and type of contamination. Site managers have many logistical considerations to balance under high time constraints. The documents below are a partial list of EPA's guidance for removals, with a focus on Non-Time-Critical Removal Actions (NTCRA). For additional information, please visit EPA's Role in Emergency Response.

OSWER 9360.0-40P, February 2000
The purpose of this guidance is to provide information on the procedures and activities EPA uses in conducting non-time-critical removal actions under CERCLA and the NCP. On-Scene Coordinators (OSCs) and Remedial Project Managers (RPMs) should use this guidance to ensure that non-time-critical removal actions are conducted in accordance with applicable laws, regulations, and EPA policy. This guidance focuses primarily on those aspects of the removal process that are unique to non-time-critical removal actions. EPA 540/F-93/057, OSWER 9360.0-32, August 1993
