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. ATCP 30.24(6)(b)2.c.c. The laboratory at which the groundwater samples are to be tested for aldicarb residues. Groundwater samples shall be promptly tested for aldicarb residues after the samples are collected. Test methods shall be approved by the department and have a limit of detection at or below one part per billion. Groundwater test results shall be promptly forwarded to the department. ATCP 30.24(6)(b)3.3. The owner of each monitoring well site under par. (a) shall agree in writing, prior to the aldicarb application, that: ATCP 30.24(6)(b)3.a.a. Groundwater test results obtained from the monitoring well may be used to prohibit future aldicarb applications to the application site, as appropriate pursuant to ch. 160, Stats., and department rules, if the groundwater test results indicate that aldicarb residues are present in groundwater at a concentration of 10 parts per billion or more. ATCP 30.24(6)(b)3.b.b. The department may at reasonable times, and upon prior notice to the owner of the monitoring well site, inspect the monitoring well and collect groundwater samples from the monitoring well. ATCP 30.24(6)(c)(c) This subsection does not apply to controlled applications of aldicarb for research purposes, if authorized by the department under sub. (5) (c). ATCP 30.24(7)(a)(a) How and to whom issued. A summary special order under sub. (5) or (6) shall be issued to each person identified in the corresponding report of intended application. A summary special order shall be signed by the division administrator or the administrator’s designee, and be served in person or by certified mail, return receipt requested. ATCP 30.24(7)(b)(b) Coverage; effective date and duration. A summary special order under sub. (5) or (6) shall prohibit all proposed applications of aldicarb to the site or sites described in the order, except as specifically provided under sub. (6). A summary special order under sub. (5) or (6) becomes effective on the date of service. ATCP 30.24 NoteNote: A “proposed application” means an application described in a report of intended application under sub. (3).
ATCP 30.24(7)(c)(c) Timely response to notice of intended application. A summary special order, if issued under sub. (5) or (6), shall be issued within 30 days after a report of intended application is filed with the department. This subsection does not prohibit the department from issuing a summary special order under sub. (5) at a later date, based on new information received more than 30 days after the date on which the report of intended application was received by the department. ATCP 30.24(7)(d)(d) Right of hearing. Summary special orders are subject to a subsequent right of hearing before the department upon request, as provided in s. 94.71 (3) (c), Stats. Hearings shall be limited to the issue of whether the department has correctly interpreted and applied this section. ATCP 30.24(7)(e)(e) Violations prohibited. No person may apply aldicarb in violation of a special order issued by the department under this section. No person may violate the terms and conditions of a monitoring agreement under sub. (6). ATCP 30.24(8)(a)(a) General. A proposed application site is subject to prohibition, for purposes of sub. (5), if the proposed application site is located wholly or in part within a prohibition area under this subsection. ATCP 30.24(8)(b)1.1. A prohibition area is created to include every township quarter-quarter section lying wholly or in part within one mile of a point of standards application at which aldicarb residues have been detected in groundwater at a concentration of 10 ppb or more, based on a reliable groundwater test result received by the division. The prohibition area is created on the date when the groundwater test result is received by the division. The one mile radius from the point of standards application shall be calculated from the center point of the township quarter-quarter section in which the actual point of standards application is located. ATCP 30.24(8)(b)2.2. If any prohibition area is contiguous with or overlaps 2 or more other prohibition areas, there is created a new prohibition area which includes each quarter-quarter section any part of which lies within a 2-mile radius of each point of standards application used in determining the need for the contiguous or overlapping prohibition areas.
