Subpart F - GROUNDWATER PROTECTION RELEASES FROM SOLID WASTE MANAGEMENT UNITS
Section 61-79.264.F.101 - Corrective action for solid waste management units

(a) The owner or operator of a facility seeking a permit for the treatment, storage or disposal of hazardous waste must institute corrective action as necessary to protect human health and the environment for all releases of hazardous waste or constituents from any solid waste management unit at the facility, regardless of the time at which waste was placed in such unit.

(b) Corrective action will be specified in the permit application in accordance with this section and subpart S of this part. The permit application will contain schedules of compliance for such corrective action (where such corrective action cannot be completed prior to issuance of the permit) and assurances of financial responsibility for completing such corrective action. (amended 11/90)

(c) The owner or operator must implement corrective actions beyond the facility property boundary, where necessary to protect human health and the environment, unless the owner or operator demonstrates to the satisfaction of the Department that, despite the owner's or operator's best efforts, the owner or operator was unable to obtain the necessary permission to undertake such actions. The owner/operator is not relieved of all responsibility to clean up a release that has migrated beyond the facility boundary where offsite access is denied. Onsite measure to address such releases will be determined on a case-by-case basis. Assurances of financial responsibility for such corrective action must be provided.

(d) This section does not apply to remediation waste management sites unless they are part of a facility subject to a permit for treating, storing or disposing of hazardous wastes that are not remediation wastes.

(e) All monitoring wells to be installed pursuant to 264.101 must be cased in a manner that maintains the integrity of the monitoring well bore hole. This casing must be screened or perforated and packed with gravel or sand, where necessary, to enable collection of groundwater samples. The annular space (i.e., the space between the bore hole and well casing) above the sampling depth must be sealed to prevent contamination of samples and the groundwater. More sophisticated monitoring well construction may be required if deemed necessary by the Department. All monitoring wells will have a locking cap or other security devices to prevent damage and/or vandalism. Each well will be labeled with an identification plate constructed of a durable material affixed to the casing or surface pad where it is readily visible. The plate will provide monitoring well identification number, date of construction, total well depth, static water level, and driller certification number. [Note: See for guidance EPA's RCRA Ground-Water Monitoring Technical Enforcement Guidance Document, TEGD]. (6/95)

(f) If not otherwise proposed as part of a plan submitted for approval by the Department, the general design, construction, and location of monitoring wells installed for the purpose of investigating groundwater contamination from solid waste management units will be submitted to the Department for approval prior to installation.
