§ 130d.51. General requirements.
(a) Special land application proposal form. A person seeking approval to utilize and apply groundwater contaminated with agricultural chemicals generated as a result of remediation activities at an agricultural chemical facility as tank mix, shall apply in writing on a special land application proposal form prepared by the Department. The person seeking permission shall follow the land proposal application procedures in Subchapters B and D (relating to land application proposal requirements for permission to apply soil and groundwater contaminated with agricultural chemicals to agricultural land; and general operating requirements for land application of soil and groundwater contaminated with agricultural chemicals to agricultural land).
(b) Review and approval of special land application proposal form. The Department will follow the review process in Subchapter C (relating to land application proposal review procedures) when reviewing an application for use of groundwater contaminated with agricultural chemicals as tank mix. When the Department permits groundwater contaminated with agricultural chemicals, generated as a result of remediation activities at an agricultural chemical facility, to be applied as tank mix to agricultural land, the applicant shall comply with the provisions of this chapter except those expressly waived in writing by the Department in its letter of approval.
(c) Denial of special land application proposal form. When the Department denies a request to utilize and apply groundwater contaminated with agricultural chemicals as tank mix, the person seeking approval may still submit a land application proposal form under the standard provisions of this chapter. The Department’s letter of denial will set forth the reasons for the denial.
(d) Ongoing testing and monitoring requirement. When the Department approves the application of groundwater contaminated with agricultural chemicals, as tank mix, the approved applicant shall be required to conduct quarterly testing and monitoring of the groundwater and submit the results of the tests to the Department. The testing shall be done in accordance with § § 130d.22 and 130d.23 (relating to chemical analysis of waste and sampling techniques and protocol; and waste sampling plan), shall test and monitor for the agricultural chemicals set forth in the applicant’s approved land application proposal and shall be consistent with the land application proposal approved by the Department. The approved applicant shall continue to monitor and test until a final closure plan has been submitted to and approved by the Department and pumping and application of the groundwater contaminated with agricultural chemicals has ceased. This requirement applies to each well or other source from which the groundwater contaminated with agricultural chemicals to be utilized as tank mix is being drawn or pumped. Based on the quarterly test results and consistent with the rates and procedures in § § 130d.41—130d.45, the Department may allow or require the approved applicant to change the rates of application.
(e) Cancellation of approval to utilize and apply groundwater contaminated with agricultural chemicals as tank mix. The Department will cancel the approval to utilize and apply groundwater contaminated with agricultural chemicals as tank mix if the groundwater contamination levels rise above the DEP published MCL and HAL standards or new contaminants are found. The utilization and land application of the contaminated groundwater as tank mix shall immediately cease. The previously approved applicant shall no longer fall under the exception established by this subchapter and delineated in the Department’s letter of approval. The previously approved applicant shall be required to either cease and desist or, where possible, comply with the standard land application requirements of this chapter. Land application of the groundwater contaminated with agricultural chemicals may not resume until the previously approved applicant can demonstrate compliance with this chapter.
