Guardian -Operator S Submittal Checklist 2008 (For Steps 1 and 7 )

GUARDIAN -OPERATOR’S SUBMITTAL CHECKLIST 2008 (FOR STEPS 1 AND 71) Place a check mark beside each item submitted (or completed, even if no written submittal is needed) Step Submitted/Completed Report Reference 1 Petroleum Risk Factor Index Table, with explanations and signature. Notify PA staff as to path chosen (Category, RBCA, Hearing). 7 BASIC SITE AND ASSESSMENT INFORMATION FOR MOST SITES Index Table, if modified after initial submission or not previously submitted. Information from initial spill & cleanup (information not already on Field Ops 1085 form). Site map with facilities, utilities, pipelines, impacted area, etc. shown. Area maps and photos available – mark the site location on one map that shows section #s. __ topographic ___ soil ___ hydrogeological ___ wellhead protection area __ aerial photo ___other: Written narrative covering site/area activities and observations (description of land use; wells/surface waters; soils; stains, odors, or other, impacts to soil/water/plants/animals.) Map showing sampling locations. Include screening information, observations, rationale. Table (preferred) or listing of soil and water analytical results, and copies of lab analyses. Boring/excavation logs. Cross-sections if made. Other relevant information. IF SALINE WATER IS/WAS PRODUCED/HANDLED AT THE SITE AND IMPACTS ARE APPARENT Have likely produced water/brine impacts been evaluated? See Appendix VIII IF MONITORING WELLS ARE INSTALLED Well installation information. Table (preferred) or listing of water sample analytical results, and copies of lab analyses. Groundwater elevation measurements, and a map showing flow direction(s). Free product information and measurements, and a plan to deal with it. TDS or TSS for waters sampled. Contoured groundwater plume map(s); depth/time/concentration graphs as necessary. FOR CATEGORY PATHWAY SITES Compare Category cleanup levels to site impact levels. Are numerical criteria met? or Data to show plume is stable (sample all around to background/Category level). Options: Bioenhancement activities or evidence of remediating bacteria/byproducts Institutional controls, if any Absence of receptors or pathways. FOR RBCA PATHWAY SITES Data documenting the RBCA processes, how RBSLs or SSTLs were calculated. RBSLs and/or SSTLs comparison to site COC levels. IF A CLEANUP AND/OR RESTORATION FOR BENEFICIAL USE WAS DONE Cleanup information, if any, with post-completion sampling results to show the site now meets appropriate Category or RBCA calculated levels. Post-action monitoring, if needed to document cleanup conditions and/or restoration. INFORMATION AND DOCUMENTATION NEEDED TO ACHIEVE CLOSURE A request for closure stating why no further action is needed at the site. Documentation that the site has been restored to beneficial use(s). Documentation that all regulatory (e.g. monitoring, proper abandonment of borings and monitoring wells), consent order, and/or other agreed upon requirements are met.

1 Data and reports will be requested prior to Step 7 if all of the work required to close a site cannot be done within one year.
