Dear Mr. Norris
PAT MCCRORY
Governor
DONALD R. VAN DER VAART
Secretary
MICHAEL E. SCOTT
Director
Thank you for your ongoing cooperation in completing Phase I of the remedial
investigation needed at the site located at 828 Martin Luther King Jr Blvd in Chapel Hill, North
Carolina (the Site). The purpose of Phase I was to identify all releases of hazardous substances
to the environment, characterize the chemical nature of such releases and collect sufficient
sampling data in order to compile a list of contaminants of concern.
Based on the results of Phase I of the remedial investigation, the North Carolina
Department of Environmental Quality's Division of Waste Management (Division) has
determined that there is a release, or substantial threat of a release into the environment of a
hazardous substance from the Site and an area accessible to the public and therefore considers
the Site to be a high priority for assessment.
In light of these facts, the Division requests that you conduct Phase II of the remedial
investigation under the supervision of the Division's Inactive Hazardous Sites Branch. Within
ninety (90) days of your receipt of this letter, please submit a draft Remedial Investigation Plan
(Plan) that complies with the current Inactive Hazardous Sites Branch Guidelines for Assessment
and Cleanup (Guidance) available at http://deq.nc.gov/about/divisions/waste-
management/waste-management-permit-guidance/inactive-hazardous-sites-guidance-documents.
The purpose of conducting Phase II of the remedial investigation is to delineate the lateral
and vertical extent of contamination in each area of concern, to concentrations less than or equal to
the unrestricted use remediation goals referenced in Section 4.1 of the Guidance or site -specific
natural background levels for metals, whichever is higher. Due to the fact that you have already
completed Phase I of the remedial investigation, as outlined in the Guidance, please refer to
Section 2.3 for details on developing a plan to complete this phase of the investigation.
