ATCP 30.24(3)(a)(a) No person may apply a pesticide containing the active ingredient aldicarb unless a report of intended application has been filed with the department at least 45 days before the pesticide is applied. Reports of intended application shall be made on forms provided by the department, and shall specify: ATCP 30.24(3)(a)1.1.

ATCP 30.24(3)(d)(d) No person may falsify information submitted under this subsection. ATCP 30.24(4)(4) Department review of proposed applications; evaluation of application sites. Whenever the department receives a report of intended application under sub. (3), the department shall evaluate the proposed application site for susceptibility to groundwater contamination by aldicarb residues. The evaluation shall be based on the relevant environmental characteristics of the proposed application site, including depth to groundwater and soil texture. Site characteristics used in the evaluation shall be determined on the basis of data published by the Wisconsin geological and natural history survey, the U.S. department of agriculture natural resources conservation service, or other reliable sources. ATCP 30.24(5)(5) Aldicarb applications to certain sites prohibited. ATCP 30.24(5)(a)(a) The department shall, by summary special order, prohibit a proposed aldicarb application if either of the following applies: ATCP 30.24(5)(a)2.2. In the judgment of the department based on a site evaluation under sub. (4), the proposed application is likely to cause aldicarb residues to be present in groundwater at a concentration of 10 ppb or more at any point of standards application. ATCP 30.24(5)(b)(b) A person prohibited from using aldicarb under par. (a) 1. may request an exemption from the prohibition. Except as provided in par. (d), the department may not grant an exemption unless the department finds all the following: ATCP 30.24(5)(b)1.1. That the concentration of aldicarb at each point of standards application used in determining the need for the prohibition has been below the enforcement standard for at least 2 years in a stable or declining pattern. ATCP 30.24(5)(b)2.2. That, to a reasonable certainty, by the greater weight of the credible evidence, application of pesticides containing aldicarb in the prohibition area will not result in noncompliance with the enforcement standard at any point of standards application used in determining the need for the prohibition. In making this determination, the department shall consider whether the prohibition was based in whole or in part on the use of pesticides containing aldicarb prior to April 1, 1983. ATCP 30.24(5)(c)(c) The department may require a person requesting an exemption under par. (b) to submit proof that the exemption requirements under par. (b) are met. The division administrator or the administrator’s designee shall issue the exemption, if any, in writing. Every exemption shall contain a specific statement of facts and conclusions which form the basis for the exemption. An exemption under par. (b) does not constitute an exemption from any other provision of this section. ATCP 30.24(5)(d)(d) Notwithstanding par. (a), the department may authorize the controlled application of aldicarb to a limited portion of a prohibition area for research purposes approved by the department. The division administrator or the administrator’s designee shall issue the authorization in writing, and shall describe the scope and basis of the authorization. ATCP 30.24(6)(6) Aldicarb applications prohibited at certain sites except in conjunction with groundwater monitoring. ATCP 30.24(6)(a)(a) If a proposed aldicarb application is not subject to prohibition under sub. (5), but the department determines under sub. (4) that the proposed application may cause aldicarb residues to be present in groundwater at a concentration of 2 ppb or more at any point of standards application, the department shall issue a summary special order prohibiting the proposed aldicarb application unless: ATCP 30.24(6)(a)2.2. The owner of the proposed application site, and every other person filing a report of intended application for the site, agrees that future applications to the site may be prohibited based on groundwater test results obtained from a representative application site chosen by the department, if the groundwater test results at the representative application site show aldicarb residues in concentrations of 10 ppb or more. A representative application site is a site which, in the department’s judgment, is similar in its relevant environmental characteristics to the proposed application site described in the report of intended application. Relevant environmental characteristics include the characteristics listed under sub. (4). In determining whether one application site may be considered representative of another, the department shall compare any prior existing concentrations of aldicarb residues which are known to be present in groundwater at the 2 sites. ATCP 30.24(6)(b)1.1. One or more monitoring wells shall be installed at the proposed application site according to a written plan which is approved in writing by the department prior to the aldicarb application. The plan shall specify: ATCP 30.24(6)(b)1.a.a. The number and location of the monitoring wells. At least one monitoring well shall be installed for each quarter section of land on which aldicarb is to be applied. ATCP 30.24(6)(b)1.c.c. The depth of each monitoring well, and the type, length, and diameter of the sample screen on each well. ATCP 30.24(6)(b)1.e.e. Whether or not each monitoring well will be considered a point of standards application. ATCP 30.24(6)(b)2.2. Groundwater samples shall be collected from each monitoring well under par. (a) and tested for aldicarb residues according to a plan which is approved by the department prior to the aldicarb application. The plan shall specify: ATCP 30.24(6)(b)2.a.a. The number of groundwater samples to be collected from each monitoring well, and the intended dates of collection.
