• Sediment Contamination from an Off-Site Source Not Remediated- General notice
• Three On-Site Commingled Plume Conditions Exist notices
• Transfer of Monitoring Well Use (Redesignated use)

The document has been revised to include additional information and corresponding examples to various instructional sections and existing Notices. Instructions and a shell document on how to withdraw a Response Action Outcome are also included. In the revised document, a Response Action Outcome Type Decision Matrix has been modified into a tabular format. Importantly, an RAO Shell Scenarios/Instructions section has been added to assist the LSRP in crafting the RAO correctly based on frequently identified scenarios. For a complete list of changes, please see the corresponding change log.

The updated guidance and change log can be found on the SRP Guidance Library (www.nj.gov/dep/srp/guidance/). The previous version of this document can be found on the SRP Guidance Library Archive (www.nj.gov/dep/srp/guidance/archive/).
