Standard Operating Procedures (SOP)

DEC is in the process of updating most of the SOPs for the monitoring equipment used throughout the state. Each link is directed to the most up to date version of the SOP, and the status/date columns will be updated as work progresses. For SOPs under revision or development, the State will use a previous version or a SOP from other state or local government agencies. The interim document is identified in the comment section and can be accessed as well. Older versions of SOPs and other guidance documents will be retained on a separate page and can be accessed below.
