List of Pollution Prevention Alternative Practices - See PDF for table PDF
1A modification to the list of practices on this table that an individual facility shall comply with to be eligible for the pollution prevention alternative is allowed with acceptable justification. This justification is listed on this table and as approved by the permitting or control authority using best practical judgment or best engineering judgment after submittal by the facility of a request for modification. A modification, for purposes of this table, means that a facility would no longer have to perform a listed practice or would need to comply with a modified practice. However, the modification only applies to the specific practice for which the modification has been justified and to no other listed practices. Facilities are required to thoroughly discuss all modifications in the on-site compliance paperwork as described in this subchapter in the limitations and standards as in s. NR 233.305(2).
2After following the practices above, some wastewaters for indirect dischargers may require pretreatment prior to discharge to POTWs. See definition of pollution prevention allowable discharge for indirect dischargers as defined in s. NR 233.305.
3After following the practices above, all wastewaters for direct dischargers shall require treatment prior to discharge directly to the state's waters. See definition of pollution prevention allowable discharge for direct dischargers as defined in s. NR 233.305.
4Additional information and guidance on implementing these pollution prevention practices as well as evaluating compliance with these practices will be available in a pollution prevention guidance manual for the PFPR industry.

List of Appropriate Treatment Technologies1
This table contains those pollutant control technologies, such as hydrolysis. chemical oxidation, precipitation, and activated carbon adsorption, which have been used for estimating compliance costs on a pesticide active ingredient basis. In general, these treatment technologies have been determined to be effective in treating pesticide containing wastewaters in literature, in bench or pilot scale treatability studies or in the pesticide manufacturing effluent guidelines. These are the same technologies that are presented as part of the universal treatment system. However, these technologies are pesticide active ingredient specific and may need to be used in conjunction with one another to provide treatment for all pesticide active ingredients used at a facility over a period of time. In addition, facilities may experience difficulties treating wastewaters that contain emulsions, therefore, “appropriate" treatment for emulsified wastewaters must include an emulsion breaking step. For pesticide active ingredients whose technology is listed as “pollution prevention", the permitting authority or control authority can determine if additional treatment is necessary through best professional judgment or best engineering judgment, respectively. - See PDF for table PDF - See PDF for table PDF
