NR 206.06NR 206.06Alternative requirements.
NR 206.06(1)(1)If the owner of a proposed land disposal system feels that compliance with the monitoring requirements, discharge prohibitions and effluent limits of this chapter are impracticable, the reasons therefore shall be fully communicated in writing to the department. This communication shall set forth alternative requirements for which department approval is sought and all pertinent facts, data, reports, and studies supporting the imposition of such alternative requirements, along with supporting documentation on the ability of the system to meet ch. NR 140 standards or standards pursuant to the appropriate variances.
NR 206.06(2)(2)If the department determines that compliance with the monitoring requirements, discharge prohibitions and effluent limits of this chapter would be impracticable in specific cases, it may approve alternative requirements which, in its opinion, are in substantial compliance with the requirements of this chapter and ch. NR 140.
