Statutory Authority: 7 Delaware Code, Chapter 74A (7 Del.C. Ch. 74A)

FINAL

Secretary’s Order No.: 2005-A-0003

I. Background

On November 22, 2004, a public hearing was held at the Lukens Drive office of DNREC in New Castle, Delaware, to receive public comment regarding the proposed revisions to Delaware’s Regulations Governing Aboveground Storage Tanks. Senate Substitute No. 1 for Senate Bill N. 344, signed by Governor Minner on July 22, 2004, amended several sections of Title 7, Del.C. Chapter 74A, The Jeffrey Davis Aboveground Storage Tank Act, which required subsequent changes in the Delaware Regulations Governing Aboveground Storage Tanks. Other changes were made to add clarification and/or provide corrections to the existing language contained within these Regulations.

The Department prepared the changes to these Regulations and presented them to the Aboveground Storage Tank Technical Advisory Committee (ASTTAC). ASTTAC worked with the Department to develop the initial set of AST Regulations promulgated in June of 2004. By unanimous vote, the ASTTAC committee members endorsed these proposed changes. A public workshop was held by the Department regarding these proposed revisions on September 30, 2004, and, as noted previously herein, the public hearing was held on November 22, 2004.

No public comments were received by the Department in either the pre-hearing phase or at the hearing itself. Subsequent to the public hearing, the Tank Management Branch of the Division of Air & Waste Management reviewed the entire record generated as a result of this rulemaking procedure, and provided a Final Response Memorandum concerning this matter to the Hearing Officer dated December 8, 2004. Thereafter, the Hearing Officer prepared her report and recommendation in the form of a memorandum to the Secretary dated January 4, 2005, and that memorandum is expressly incorporated herein by reference. Proper notice of the hearing was provided as required by law.

II. Findings and Conclusions

All of the findings and conclusions contained in the Hearing Officer’s Memorandum dated January 4, 2005, are expressly incorporated herein and explicitly adopted as the findings and conclusions of the Secretary.

III. Order

In view of the above, I hereby order that the proposed amendments be promulgated and implemented in the manner and form provided for by law, as recommended in the Hearing Officer’s memorandum.

IV. Reasons

The adoption of these proposed changes in the Delaware Regulations Governing Aboveground Storage Tanks will be beneficial to the State of Delaware, in that it will clarify and/or correct existing language currently contained within these regulations, and, most importantly, allow the Department’s AST Regulations to remain consistent with the amendments recently made to The Jeffrey Davis Aboveground Storage Tank Act this year. Additionally, the adoption of these amendments will help to improve and/or enhance the overall performance of the State of Delaware’s Tank Management Program with the Division of Air and Waste Management, in furtherance of the policies and purposes of 7 Del.C. Ch. 74A.

1.0 General Provisions

1.1 Statement of Authority and Purpose

1.1.1 These Regulations are enacted in accordance with Title 7 Del.C. Ch. 60, Environmental Control, and Title 7 Del.C. Ch. 74A, The Jeffrey Davis Aboveground Storage Tank Act.

1.1.2 The Delaware Department of Natural Resource and Environmental Control is responsible for protecting, preserving and enhancing the environmental quality of water, air and land of the State. In addition, the General Assembly of the State of Delaware has found "that it is therefore necessary to provide for more stringent control of the installation, operation, retrofitting, maintenance, repair, abandonment, and/or removal of aboveground storage tanks to prevent releases and where releases occur, to detect and remediate them at the earliest possible stage, thus minimizing further degradation of soil, air, surface water, and groundwater and promoting public safety."

The Regulations Governing Aboveground Storage Tanks are intended to address existing and potential sources of pollution that may result from ASTs. To ensure the prevention and early detection of a Release of a Regulated Substance should one occur, new tanks are required to meet acceptable design and installation criteria and existing tanks are required to upgrade by a schedule set forth to comparable standards. AST design criteria promulgated under these Regulations will minimize the risk of Regulated Substances impacting the environment.

18.1 Except as specified in §18.4 of this Part, the Department shall require the Guarantor, surety, or institution issuing a letter of credit, to place the amount of funds stipulated by the Department, up to the limit of funds provided by the financial assurance mechanism, into the standby trust if:

18.1.1 The Owner or Operator fails to establish alternate financial assurance within 60 days after receiving notice of cancellation of the guarantee, surety bond, letter of credit, or, as applicable, other financial assurance mechanisms; and

18.1.2 The Department determines or suspects that a Release from an AST covered by the mechanism has occurred and so notifies the Owner or Operator or the Owner and Operator has notified the Department pursuant to requirements established under Part E of these regulations of a Release from an AST system covered by the mechanism; or

18.1.3 The conditions of §18.2.1 or §18.2.2 of this Part are satisfied.

18.2 The Department may draw on a standby trust fund when:

18.2.1 The Department makes a final determination that a Release has occurred and immediate or long term corrective action for the Release is needed, but the Owner or Operator, after appropriate notice and opportunity to comply, has not conducted corrective action as required under Part E of these Regulations; or

18.2.2 The Department has received either:

18.2.2.1 Certification from the Owner or Operator and the third party liability claimant(s) and from attorneys representing the Owner or Operator and the third party liability claimant(s) that a third party liability claim should be paid. The certification shall be worded as shown in Appendix I of this Part except that instructions in brackets are to be replaced with the relevant information and the brackets deleted; or

18.2.2.2 A valid final court order establishing a judgment against the Owner or Operator for Bodily Injury or Property Damage caused by an Accidental Release from an AST covered by financial assurance under this Part and the Department determines that the Owner or Operator has not satisfied the judgment.

18.3 If the Department determines that the amount of corrective action costs and third party liability claims eligible for payment under §18.2 of this Part may exceed the balance of the standby trust fund and the obligation of the Provider of Financial Assurance, the first priority for payment shall be corrective action costs necessary to protect human health and the environment. The Department shall pay third party liability claims in the order in which the Department receives certifications under §18.2 of this Part.

18.4 A governmental entity acting as Guarantor under §13 of this Part, the Local Government guarantee without standby trust, shall make payments as directed by the Secretary under the circumstances described in §§18.1, 18.2 and 18.3 of this Part.

20.0 Replenishments of Required Financial Responsibility

20.1 If at any time after a standby trust is funded upon the instruction of the Secretary with funds drawn from a guarantee, Local Government guarantee with standby trust, letter of credit, or surety bond, and the amount in the standby trust is reduced below the full amount of coverage required, the Owner or Operator shall by the anniversary date of the financial mechanism from which the funds were drawn:

20.1.1 Replenish the value of financial assurance to equal the full amount of coverage required, or

20.1.2 Acquire another financial assurance mechanism for the amount by which funds in the standby trust have been reduced.

20.2 For purposes of this Section, the full amount of coverage required is the amount of financial responsibility required by §3 of this Part. If a combination of mechanisms was used to provide the assurance funds which were drawn upon, replenishment shall occur by the earliest anniversary date among the mechanisms.

Surety’s bond number: _____________________________

Know all persons by these presents, that we, the Principal and Surety(ies), hereto are firmly bound to the Department, in the above penal sums for the payment of which we bind ourselves, our heirs, executors, administrators, successors, and assigns jointly and severally; provided that, where the Surety(ies) are corporations acting as co-sureties, we, the Sureties, bind ourselves in such sums jointly and severally only for the purpose of allowing a joint action or actions against any or all of us, and for all other purposes each Surety binds itself, jointly and severally with the Principal, for the payment of such sums only as is set forth opposite the name of such Surety, but if no limit of liability is indicated, the limit of liability shall be the full amount of the penal sums.

Whereas said Principal is required under 7 Del.C. Ch. 74A, as amended, to provide financial assurance for [insert: “taking corrective action” and/or “compensating third parties for Bodily Injury and Property Damage”] caused by accidental releases; (if coverage is different for different tanks or locations, indicate the type of coverage applicable to each tank or location) arising from operating the aboveground storage tanks identified above, and

Whereas said Principal shall establish a standby trust fund as is required when a surety bond is used to provide such financial assurance;

Now, therefore, the conditions of the obligation are such that if the Principal shall faithfully [“take corrective action, in accordance with Part E of these regulations and the Department’s instructions for, compensate injured third parties for bodily injury and property damage caused by accidental releases arising from operating the tank(s) identified above, or if the Principal shall provide alternate financial assurance, as specified in Part D of these regulations, within 120 days after the date the notice of cancellation is received by the Principal from the Surety(ies), then this obligation shall be null and void; otherwise it is to remain in full force and effect.

Such obligation does not apply to any of the following:

(a) Any obligation of _____________________________ under a workers’ compensation,

[Owner or Operator] disability benefits, or unemployment compensation law or other similar law;

(b) Bodily injury to an employee of ____________________ arising from, and in [Owner or Operator] the course of, employment by [insert Owner or Operator];

(c) Bodily injury or property damage arising from the ownership, maintenance, use, or entrustment to others of any aircraft, motor vehicle, or watercraft;

(d) Property damage to any property owned, rented, loaned to, in the care, custody, or control of, or occupied by ____________________ that is not the direct result of a release from [Owner or Operator] an aboveground storage tank;

(e) Bodily injury or property damage for which [insert owner or operator] is obligated to pay damages by reason of the assumption of liability in a contract or agreement other than a contract or agreement entered into to meet the requirements of Part D, Section 3 of these regulations.

The Surety(ies) shall become liable on this bond obligation only when the Principal has failed to fulfill the conditions described above.

Upon notification by the Department that the Principal has failed to [“take corrective action, in accordance with Part E of these regulations and the Department’s instructions,” and/or “compensate injured third parties”] as guaranteed by this bond, the Surety(ies) shall either perform [“corrective action in accordance with Part E of these regulations and the Department’s instructions,” and/or “third-party liability compensation”] or place funds in an amount up to the annual aggregate penal sum into the standby trust fund as directed by the Department under Part D, Section 15 of these regulations.

Upon notification by the Department that the Principal has failed to provide alternate financial assurance within 60 days after the date the notice of cancellation is received by the Principal from the Surety(ies) and that the Department has determined or suspects that a release has occurred, the Surety(ies) shall place funds in an amount not exceeding the annual aggregate penal sum into the standby trust fund as directed by the Department under Part D, Section 15 of these regulations.

PART E

CORRECTIVE ACTION REQUIREMENTS FOR ABOVEGROUND STORAGE TANKS

1.0 Investigation

1.1 After a Release, other than those that can comply with §8.1.3 of Part A, is confirmed, the Owner and Operator shall conduct an investigation as the first step in the corrective action process unless directed to do otherwise by the Department.

1.2 The purposes of an investigation are to determine:

1.2.1 The nature of the Release, including the chemical compounds present, their concentrations, quantity released and their physical and chemical characteristics related to potential human health and environmental impacts and cleanup procedures; and,

1.2.2 The extent of the Release, both horizontal and vertical, including whether the contaminant is distributed homogeneously or heterogeneously; and,

1.2.3 The physical characteristics of the site, including characteristics affecting the occurrence, distribution, and movement of the released contaminant and characteristics affecting access to the site, both horizontal and vertical, which may influence the feasibility of various investigatory and remediation procedures; and

1.2.4 An evaluation of the potential risks posed by the Release including identification of environmentally sensitive receptors, and estimate of the impacts to human health and the environment that may occur as a result of the Release.

1.3 The Department must receive the results of the investigation no later than 120 days after the Release was reported and confirmed. Upon receiving the investigation report, the Department shall review the report and either accept the conclusions and recommendations of the report, require additional information to be submitted, or require that the Owner and Operator submit a corrective action work plan as required by §3 of this Part. Additional investigation information or corrective action work plans requested by the Department must be submitted within ninety (90) days or other Department approved schedule.

1.4 The Owner and Operator may submit investigation reports for a site separately or as part of a proposed long-term corrective action work plan.

1.5 At any point after reviewing the information contained in the investigation report, the Department may require Owner and Operator to submit additional information or to develop and submit a corrective action work plan for responding to contaminated soils, surface water and/or ground water.

2.0 Administrative Option for Corrective Action

2.1 The Department may waive the requirement of a investigation when the Owner and Operator has taken the appropriate initial response steps to eliminate imminent dangers and to prevent any further Release and chooses to submit a corrective action work plan for remediating contaminated soil, ground water and/or surface water.

2.2 If the Department determines that the implementation of corrective actions are not achieving adequate protection of human health and the environment, the Department may require additional responses to be taken.

2.3 The Owner and Operator may, in the interest of minimizing environmental contamination and promoting more effective corrective action, begin remediation of soil and ground water before the corrective action work plan is approved provided that they:

2.3.1 Notify the Department of their intention to begin remediation; and,

2.3.2 Comply with any conditions imposed by the Department, including halting remediation or mitigating adverse consequences from cleanup activities; and

2.3.3 Incorporate these self-initiated remediation measures in the corrective action work plan that is submitted to the Department for approval pursuant to §3 of this Part.

3.0 Corrective Action

3.1 Corrective Action Work Plan General Requirements

3.1.1 The corrective action work plan shall address the contamination of soils, ground water and surface water as identified in the investigation report. A corrective action work plan must provide for adequate protection of the human health, safety and the environment and shall be modified to comply with the requirements contained in these Regulations as necessary.

3.1.2 The Department shall not approve any corrective action work plan that does not ensure adequate protection of human health, welfare, safety and the environment.

3.1.3 An Owner and Operator who submits a work plan that does not provide for adequate protection of human health, safety and/or the environment at the Department's discretion must modify their corrective action work plan and resubmit to the Department within a timeframe specified by the Department.

3.1.4 All corrective action work plans must be prepared using guidelines established by the Department.

3.2 Approval Requirements for Corrective Action Work Plans

3.2.1 A corrective action work plan must propose a corrective action option for the site which shall:

3.2.1.1 Address the removal of Free Product to the maximum extent practicable as determined by the Department; and

3.2.1.2 Reduce the contaminant levels at the site based on site-specific information, including the investigation report, in order to protect human health, safety, and the environment, or

3.2.1.3 Reduce the contaminant levels to achieve the clean-up goals negotiated between the Owner and Operator and the Department, or

3.2.1.4 Reduce the contaminant levels to achieve the clean-up goals established by the Department, and

3.2.1.5 Monitor the site over time to provide technically-based assurance that the site contamination is controlled under natural conditions and that those conditions will not now, or at some future time, adversely impact human health, safety or the environment.

3.2.2 The Department will approve the corrective action work plan only when satisfied that implementation of the corrective action work plan provides for measures considered adequate to protect human health, safety, and the environment. In making this determination, the Department shall consider the following factors as appropriate:

3.2.2.1 The physical and chemical characteristics of the Regulated Substance, including its toxicity, persistence, and potential for migration;

3.2.2.2 The report of the investigation conducted under §1of this Part;

3.2.2.3 The proximity, quality, and current and future uses of nearby surface water and ground water and soil;

3.2.2.4 An exposure assessment;

3.2.2.5 Any information assembled in compliance with this Part of the Regulations; and

3.2.2.6 The potential effects of residual contamination on nearby surface water and groundwater and soil.

3.2.3 The corrective action work plan must be organized in report form and all or portions of the report may be required to be signed by a professional geologist or Professional Engineer registered in the State of Delaware as determined by the Department.

3.2.4 The corrective action work plan may propose a phased approach to site remediation.

3.3 Quality Assurance/Quality Control

3.3.1 A site-specific Quality Assurance/Quality Control (QA/QC) plan for the activities to be carried out during implementation of the corrective action work plan must be formulated and approved by the Department prior to the implementation of any site activities. This QA/QC Plan shall be included in the corrective action work plan and cover all actions proposed in the work plan.

3.4 Site Safety

3.4.1 A site-specific health and safety plan must be included in the corrective action work plan and shall cover all corrective action tasks. The health and safety plan must address the site worker protection levels, protection of persons living near the site and site access control during remediation.
