The report must include, but is not necessarily limited to, the following:

(1)   Data on the nature and estimated quantity of the release.

(2)   Data from available sources and/or site investigations concerning the following factors:

(A)   Surrounding populations.

(B)   Water quality (regional).

(C)   Use and approximate locations of water wells, basements, storm cellars, and all subsurface crawl spaces potentially affected by the release within 330 feet from the source, and any wellhead protection delineations.

(D)   Subsurface soil conditions.

(E)   Locations and depths of subsurface utilities and petroleum storage tank systems.

(F)   Climatological conditions.

(G)   Land use.

(H)   Depth to and quality of groundwater (site-specific).

(I)   Latitude and longitude of the center of the tankpit to the nearest second.

(3)   Results of the site check and/or the closure site assessment required by 165:29-3-65.

(4)   Results of the free product investigations.

(b)   Within twenty (20) days of release confirmation or according to a schedule set by the PSTD, the owner or operator must submit the information collected in compliance with this Section to the PSTD, in a manner established by PSTD that demonstrates its applicability and technical adequacy.

(c)   The owner or operator must submit a Corrective Action Plan (CAP) to the PSTD as a separate part of the report required in this Section, identifying a plan of action to:

(1)   Perform an ORBCA Tier 1A analysis to determine the need, if any, for remediation and/or additional ORBCA analyses.

(2)   Monitor air, water, and soil.

(3)   Remediate the release to such an extent that it no longer poses a threat to human health or safety or the environment.

(d)   On Tier 1A, Tier 2 and Tier 3 ORBCA, case prioritization will be established by the PSTD using the Storage Tank Prioritization Guidance Document.
