§ 130d.22. Chemical analysis of waste and sampling techniques and protocol.
(a) General criteria. A person who seeks to apply soil or groundwater, generated as a result of remediation activities at an agricultural chemical facility, to agricultural land shall perform a detailed analysis and testing of the soil or groundwater, or both, at the agricultural chemical facility site and the application site. A verified copy of the sampling techniques and results shall be submitted to the Department as part of the land application proposal.
(b) Analysis and testing of the soil or groundwater, or both, at the agricultural chemical facility site. The analysis and testing at the agricultural chemical facility site shall fully characterize the physical properties and chemical composition of each type of agricultural chemical that was held, stored, blended, formulated, sold, distributed, manufactured or generated by the agricultural chemical facility and shall be done in accordance with subsections (d) and (e)(1) and (2). The substances tested for shall be predicated on the manufacturing processes and business carried on at the agricultural chemical facility site being remediated and records obtained from that agricultural chemical facility or facilities on that site. The types of agricultural chemicals likely to be contained in the soil and groundwater shall be gleaned from information available regarding the agricultural chemical facility site at which the remediation activities are taking place including the following:
(1) Records, including sales records, memorandums, invoices and historical data, of the type of products manufactured, held, stored, formulated, sold, distributed, produced or used.
(2) Material safety data sheets or similar sources that may help characterize the types of agricultural chemicals and waste generated.
(3) Notices of past spills, violations or contamination if applicable.
(4) Information regarding any agricultural chemical byproduct or agricultural chemical produced during or as a result of the manufacturing processes, mixing, storage or distribution of materials.
(c) Analysis and testing of soil at the proposed application site. The analysis and testing at the proposed application site shall cover soil samples taken from the proposed application site and shall be done in accordance with subsections (d) and (e)(3). The soil samples taken from the proposed application site shall be tested for each agricultural chemical, nutrient or constituent found in the soil or groundwater, or both, at the agricultural chemical facility site that is proposed to be applied to the application site. In addition, the proposed application site analysis shall delineate the soil types found within the proposed application area. The testing and analysis of the soil at the proposed application site, at minimum, shall include:
(1) A chemical, nutrient and constituent analysis of each 15-acre field or plot upon which a soil pile or quantity of groundwater from the remediated agricultural chemical facility site is to be applied.
(2) Testing for all agricultural chemicals, the by-products or derivatives thereof, and each agricultural chemical, nutrient or constituent that was found to be present in the contaminated soil or groundwater, or both, at the agricultural chemical facility being remediated which are to be applied at the proposed application site.
(3) Documentation of the soil types found within the proposed application area.
(d) Approved laboratory. Soil or groundwater samples, or both, from each soil pile or quantity of groundwater taken from the agriculture chemical facility site being remediated and sought to be applied to agricultural land and soil samples taken from the application site shall be tested on a parts per million basis and shall be submitted for analysis to a laboratory compliant with the United States Environmental Protection Agency’s (EPA) Good Laboratory Practices (GLP) Program. A list of EPA GLP compliant laboratories is available on the Department’s website. A copy of the test results shall be submitted to the Department as part of the land application proposal and to the owner of the agricultural land on which the contaminated soil and groundwater is sought to be applied.
(e) Sampling techniques. Sampling techniques shall be consistent with the sampling procedures set forth in the Pennsylvania Agronomy Guide which are set forth herein.
(1) Soil pile samples from the agricultural chemical facility remediation site. Sampling of soil piles from an agricultural chemical facility remediation site shall consist of one representative sample from each soil pile proposed to be land applied. A representative sample shall consist of 15 core samples from each soil pile at the remediation site which is proposed to be land applied to an agricultural site. A soil pile shall contain no more than 36,000 cubic yards of soil, which represents the cubic yards of soil contained in 15 acres of land at a 6-inch depth and is consistent with the standards established in the Pennsylvania Agronomy Guide. Multiple soil piles require multiple samples. Samples shall be collected and recorded in the following manner:
(i) Fifteen core samples shall be collected from each soil pile proposed to be land applied.
(ii) Each core sample shall be collected from a depth of at least 4 to 6 inches.
(iii) The core samples taken from each soil pile shall be mixed in order to acquire a representative sample from that particular soil pile.
(iv) Roots, stones and other debris not representative of the substrate being sampled and proposed for land application shall be removed from the core samples.
(v) The mixed sample from each soil pile shall be placed in a clean unused container and marked in a manner delineating the particular soil pile from which the sample was taken. The sample container shall be compliant with the standards established by the approved laboratory to which the soil samples will be submitted for testing.
(vi) The applicant shall complete the required report form, set forth the agricultural chemicals to be tested for, in compliance with the requirements of this chapter, and submit the sample or samples to an approved laboratory.
(2) Water samples from the agricultural chemical facility remediation site. Where groundwater from an agricultural chemical facility remediation site is proposed to be applied to agricultural land, the applicant shall collect 1 pint of water from the remediation site for every 2,000 gallons of water sought to be land applied or utilized as tank mix. Samples shall be collected and recorded in the following manner:
(i) Samples shall be collected from random and mixed points and depths throughout the remediation site to assure a true and representative sampling of the water contaminated with agricultural chemicals at the remediation site.
(ii) Samples shall be collected in clean unused glass bottles and kept chilled during and prior to delivery to an approved laboratory.
(iii) Samples shall be marked in a manner delineating the particular site location and depth from which the sample was taken.
(iv) The applicant shall complete the required report form, set forth the agricultural chemicals to be tested for, in compliance with this chapter, and submit the sample or samples to an approved laboratory.
(3) Soil samples from the proposed application site. Sampling of soil from the proposed application site shall consist of one representative sample per every 15 acres of land upon which the soil contaminated with agricultural chemicals from the agricultural chemical facility is proposed to be land applied. Samples shall be collected and recorded in the following manner:
(i) A representative sample shall consist of 15 core samples collected from 15 different areas per 15-acre plot (one core sample taken from each acre on that plot) of land area proposed to receive soil or water, or both, contaminated with agricultural chemicals from an agricultural chemical facility being remediated under the act.
(ii) Core samples shall be collected from a depth of at least 4 to 6 inches.
(iii) The 15 core samples collected from each 15-acre plot shall be thoroughly mixed to get a representative sample from that 15-acre plot.
(iv) Roots, stones and other debris not representative of the field plot being sampled shall be removed from the core samples.
(v) The mixed sample from each 15-acre plot shall be placed in a clean, unused container and marked in a manner delineating the particular 15-acre plot from which the sample was taken. The sample container shall be compliant with the standards established by the approved laboratory to which the soil sample will be submitted for testing.
(vi) The applicant shall complete the required report form, set forth the agricultural chemicals to be tested for and submit the sample or samples to an approved laboratory.
