160.19(1) (1) When an enforcement standard or a preventive action limit is established by rule for a substance, each regulatory agency shall review its rules and commence promulgation of any rules or amendments of its rules necessary to ensure that the activities, practices and facilities regulated by the regulatory agency will comply with this chapter.
160.19(2) (2)
160.19(2)(a) (a) Each regulatory agency shall promulgate rules which define design and management practice criteria for facilities, activities and practices affecting groundwater which are designed, to the extent technically and economically feasible, to minimize the level of substances in groundwater and to maintain compliance by these facilities, activities and practices with preventive action limits, unless compliance with the preventive action limits is not technically and economically feasible.
160.19(2)(b) (b) If a regulatory agency proposes a rule under par. (a) which is not designed to maintain compliance with preventive action limits, the proposed rule and the notice required under s. 227.16 (2) (e) , 227.17 or 227.24 (3) shall include a statement to that effect, and a summary of the rationale for the proposed rule. If a regulatory agency determines not to amend the substance of an existing rule which contains design or management practice criteria that do not maintain compliance with preventive action limits, it shall nonetheless amend the rule to include a notice that the rule does not maintain preventive action limits. A summary of the rationale for not amending the substance of the rule shall be included in the notice required under s. 227.16 (2) (e) , 227.17 or 227.24 (3) .
160.19(3) (3) A regulatory agency may not promulgate rules defining design and management practice criteria which permit an enforcement standard to be attained or exceeded at the point of standards application.
160.19(4) (4) Notwithstanding previous regulatory agency action to review and amend existing rules or to promulgate new rules:
160.19(4)(a) (a) If a rule is designed to maintain compliance with a preventive action limit under sub. (2) (a) and if a preventive action limit is attained or exceeded at a point of standards application, the regulatory agency shall review its rules and, if necessary, revise the rules to maintain or achieve the objectives of subs. (2) and (3) .
160.19(4)(b) (b) If an enforcement standard is attained or exceeded at a point of standards application, the regulatory agency shall review its rules and, if necessary, revise the rules to ensure that the enforcement standard is not attained or exceeded at a point of standards application at other locations in the future.
160.19(5) (5) In conducting any review under sub. (4) , the regulatory agency’s analysis shall include an examination of the performance of other comparable activities in the state to determine if the noncompliance at a single site suggests an isolated problem or a problem which is likely to recur.
160.19(6) (6) The department shall promulgate by rule a scientifically valid procedure for determining if a preventive action limit or enforcement standard is, in fact, attained or exceeded or if a change in concentration of a substance has, in fact, occurred. This procedure shall be used for all regulatory and enforcement purposes under this chapter.
160.19(7) (7) Notwithstanding subs. (2) and (4) (a) , modifications to rules and changes in the manner of their administration are not required under this section solely because the background concentration of nitrate or a substance of public welfare concern at individual locations is equal to or greater than the preventive action limit.
160.19(8) (8) Notwithstanding subs. (2) to (4) , the department may allow a facility which is regulated under chs. 283 or 289 to 292 to be constructed, after May 11, 1984, in an area where the background concentration of nitrate or a substance of public welfare concern attains or exceeds the preventive action limit or the enforcement standard if the facility is designed to achieve the lowest possible concentration for that substance which is technically and economically feasible and the anticipated increase in the concentration of the substance does not present a threat to public health or welfare.
160.19(9) (9) Notwithstanding subs. (2) to (4) , the department may allow a facility which is regulated under chs. 283 or 289 to 292 to be constructed, after May 11, 1984, in an area where the background concentration of a substance of public health concern, other than nitrate, attains or exceeds a preventive action limit for that substance:
160.19(9)(a) (a) If the facility will not cause the further release of that substance into the environment;
160.19(9)(b) (b) If the background concentration of the substance does not exceed the enforcement standard for that substance, the facility will not cause the concentration of the substance to exceed the enforcement standard for that substance and the facility is designed to achieve the lowest possible concentration of that substance which is technically and economically feasible; or
160.19(9)(c) (c) If the background concentration of the substance equals or exceeds the enforcement standard for that substance, the facility is designed to achieve the lowest possible concentration of that substance which is technically and economically feasible, the anticipated increase in the concentration of the substance will not cause an increased threat to public health or welfare and the anticipated incremental increase in the concentration of the substance, by itself, will not exceed the preventive action limit. The department shall take action under s. 160.25 if it determines that the increase in the substance causes an increased threat to public health or welfare or it determines that the incremental increase in the concentration of the substance, by itself, exceeds the preventive action limit.
160.19(10) (10) If the department allows a facility to be constructed under sub. (9) (b) or (c) , the department shall specify in the initial approval of or the initial or modified permit for the facility the terms and conditions under which the department may seek remedial action for the specific site under ss. 160.23 and 160.25 , relating to the substance.
160.19(11) (11) Regulatory agencies shall enforce rules promulgated under this section with respect to specific sites in accordance with ss. 160.23 and 160.25 .
160.19(12) (12) The requirements in this section shall not apply to rules governing an activity regulated under ch. 293 or subch. III of ch. 295 , or to a solid waste facility regulated under subch. III of ch. 289 which is part of an activity regulated under ch. 293 or subch. III of ch. 295 , except that the department may promulgate new rules or amend rules governing this type of activity, practice or facility if the department determines that the amendment or promulgation of rules is necessary to protect public health, safety or welfare.
