1352 Aboveground Storage Tanks

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 Resources 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 release of a Regulated Substance regulated substance should one occur, new tanks ASTs are required to meet acceptable design and installation criteria and existing tanks ASTs are required to upgrade retrofit by a schedule set forth to comparable standards. AST design criteria promulgated under these Regulations will minimize the risk of Regulated Substance regulated substances impacting the environment. Release confirmation and remediation standards are set forth to require the clean-up of any Release release that does occur.

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.

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 _____________________________ [Owner or Operator] under a workers??? compensation, [Owner or Operator] disability benefits, or unemployment compensation law or other similar law;

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

(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.

The Surety(ies) hereby waive(s) notification of amendments to applicable laws, statutes, rules, and regulations and agrees that no such amendment shall in any way alleviate its (their) obligation on this bond.

The liability of the Surety(ies) shall not be discharged, by any payment or succession of payments hereunder, unless and until such payment or payments shall amount in the annual aggregate to the penal sum shown on the face of the bond, but in no event shall the obligation of the Surety(ies) hereunder exceed the amount of said annual aggregate penal sum.

The Surety(ies) may cancel the bond by sending notice of cancellation by certified mail to the Principal, provided, however, that cancellation shall not occur during the 120 days beginning on the date of receipt of the notice of cancellation by the Principal, as evidenced by the return receipt.
