1375 Regulations Governing Hazardous Substance Cleanup
1. TITLE OF THE REGULATIONS:
Delaware Regulations Governing Hazardous Substance Cleanup
2. BRIEF SYNOPSIS OF THE SUBJECT, SUBSTANCE AND ISSUES:
The premise of the Brownfields Development Program (BDP) is to provide liability protections to parties who did not cause or contribute to the release of a hazardous substance on a real property. The intent is to investigate the property, ascertain the quantity and quality of contamination, its fate, transport, and pathways from the source material, and ultimately the potential harm to affected receptors. Upon completion of the investigation, an eligible brownfield developer would have to remediate the property before putting the property back into reuse. This would cleanup the property for the intended use and prevent any further migration of contamination off of the certified brownfield property.
Remediation of contamination that extends beyond the boundaries of a Brownfield property is not the responsibility of the Brownfield developer but rather all otherwise potentially responsible parties. As the regulations are currently written, certified brownfields are "facilities" which mandates the investigation and cleanup of hazardous substance releases wherever they may be located - on or off the certified brownfield property. The amendments to the Regulations create a definition of a "certified brownfield" to ensure the remedial responsibilities of the Brownfield Developer are limited only to the area of the certified brownfield.
In addition the terminology of "abandoned, vacant or underutilized" to define a potential brownfield has been changed to "the redevelopment, reuse or expansion may be hindered by the reasonable belief that the real property is environmentally contaminated" to mirror the language in the Brownfields Development Program enabling statute, 7 Del.C. Chapter 91. The statutory change was made to more closely align with the federal brownfield statute and regulations. While the change is not required by any federal mandate it will create consistency between the state and federal brownfields program that will assist in grant writing.
3. POSSIBLE TERMS OF THE AGENCY ACTION:
There is no sunset date for the Regulations.
4. STATUTORY BASIS OR LEGAL AUTHORITY TO ACT:
7 Del.C. Chapter 91
5. OTHER REGULATIONS THAT MAY BE AFFECTED BY THE PROPOSAL:

Upon finding that a release of a hazardous substance may injure, or may have injured, trust resources of the State, the Department may conduct, either alone or in cooperation with trustee agencies of the Federal government, tribes, or other states:
220.127.116.11 A pre-assessment screen to determine whether the release justifies a natural resource damage assessment;
18.104.22.168 Sampling and data collection for the purpose of obtaining evidence which would otherwise be lost; or
22.214.171.124 Emergency response activities to the extent the Department deems appropriate to prevent or reduce actual or potential injuries to natural resources.
14.4.2 Pre-Assessment Screen
126.96.36.199 The pre-assessment screen includes a review of existing information, preliminary identification of natural resources potentially at risk, sampling, preliminary identification of the substances released, preliminary identification of pathways of exposure, and costs of performing an assessment.
188.8.131.52 Based on information gathered pursuant to the pre-assessment screen, the Department may make a preliminary determination that the following criteria are substantially met before proceeding with an assessment:
184.108.40.206.1 A release of a hazardous substance has occurred or may occur:
220.127.116.11.2 Natural resources for which the State may assert trusteeship have been or are likely to have been adversely affected by the release or potential release;
18.104.22.168.3 The quantity and concentration of the released or potentially released hazardous substances is potentially sufficient to cause injury to those natural resources;
22.214.171.124.4 Data sufficient to pursue an assessment are readily available or likely to be obtained at reasonable cost; or
126.96.36.199.5 Remedial actions, if any, carried out or planned, do not or will not sufficiently remedy the injury to natural resources without further action.
14.5 Assessment Phase
14.5.1 If a damage assessment is determined to be appropriate in the pre-assessment phase, the Department, alone or in conjunction with other Trustees or PRPs, may develop a damage assessment plan. Assessments may be conducted using the procedures outlined in 43 CFR Part 11, as amended, or by other procedures determined to be appropriate by the Department. The damage assessment plan may be incorporated into the remedial investigation work plan.
14.5.2 The assessment is conducted in the following three stages: injury determination, quantification, and damage determination.
188.8.131.52 Injury Determination: This determines whether an injury to one or more natural resources or natural resource services may have occurred, and whether the injury may have resulted from the release of a hazardous substance.
184.108.40.206 Quantification: If it is determined that there may be an injury to a natural resource or natural resource service, the magnitude of the injury may be evaluated.
220.127.116.11 Damage Determination: This determines the damages resulting from the release of a hazardous substance based upon the information provided in the injury determination and quantification stages. Restoration Valuation, and one or both of the additional valuation approaches outlined below, may be used in the Damage Determination.
18.104.22.168.1 Restoration Valuation: This methodology consists of damage estimation based on restoration or replacement of the injured natural resource due to the release of a hazardous substance. An evaluation of restoration alternatives may be conducted. The evaluation considers a range of actions to restore the injured services over various recovery periods, and may include a "no-action" or natural recovery alternative. The expected net present value of each restoration alternative shall be determined; and
22.214.171.124.2 Use Value Valuation: These methodologies consist of damage estimations based on the reduction of use values, including hiking, fishing, hunting, boating, or camping. The use values of the injured resource may be estimated by using approaches specified by the Department; and/or
126.96.36.199.3 Nonuse Value Valuation: These methodologies consist of damage estimations based on the reduction of nonuse values, including aesthetics. The nonuse values of the injured resource may be estimated by using approaches specified by the Department.
14.5.3 The results of an assessment performed by other persons shall be submitted to the Department for its approval.
14.6 Post-Assessment Phase
14.6.1 Upon completion of the assessment, the Department may, as appropriate:
188.8.131.52 Require persons to provide compensation for the injury to natural resources and natural resource services;
184.108.40.206 Seek compensation from an appropriate trust fund;
220.127.116.11 Select an appropriate restoration alternative pursuant to 14.6.2;
18.104.22.168 Develop, or require a person to develop, a restoration plan. The plan describes the specific actions to be taken to restore, replace, and/or provide compensation for the injured natural resources and natural resource services;
22.214.171.124 Implement, or require a person to implement, the approved restoration plan;
126.96.36.199 Recover its costs for assessment, restoration planning, restoration, and post-restoration activities from a person or appropriate trust fund.
14.6.2 In the evaluation of restoration alternatives, the Department may:
188.8.131.52 Consider whether the proposed restoration projects serve to restore, replace, or acquire the equivalent of the natural resources and natural resource services injured as a result of the subject releases; or
184.108.40.206 Consider projects benefitting the watershed, aquifer, populations, or species injured, and projects benefitting other watersheds, aquifers, populations, or species. Preference may be given to projects that benefit the affected watershed, aquifer, populations, or species.
