meet the standards maybe presumed to have taken into consideration economic /actors unless:
a) Anew permit is issued where the discharge was not in existence at the time of the classification and
standards rulemaking, or
b) In the case o(a continuing discharge, additional information or (actors have emerged that were not
anticipated or considered at the time of the c/ass cation and standards rulemaking.'
¢, Economic Reasonableness Evaluation: (cont.) evaluation shows that this is a new permit which was not
in existence of the time of water quality standards rulemaking. However, based on available data, the
resulting water quality standard-based effluent IimRa0ons are determined to be reasonably related to the
economic, environmental, public health, and energy impacts to the public and affected persons. 1f the
permittee disagrees with this finding, pursuant to 61.11(b2)(ii) of the Colorado Discharge Permit System
Regulations, the permittee should submit all pertinent information to the Division durtng the public notice
pedod.
7. Waste Minimization/Pollution Prevention
Waste minimization and polution prevention are two terms that are becoming increasingly more common in
industry today. Waste minimization includes reducing the amount of waste at the source through changes in
industrial processes, and reuse and recycling of wastes for the original or some other purpose (such as
materials recovery or energy production). Pollution prevention goes hand-in-hand with waste minimizabion. If
the waste is eliminated at the front o(the line, it will not have to be Veated at the end of the line. The direct
benefrts to the industry are often sign cant, both in terms of increased profit and in public relations. This
program can affect all areas of process and waste control with which an industry deals. Elimination or
reduction of a wastewater pollutant can also result in a reduction in an air pollutant or a reduction in the
amount of hazardous materials which must be handled or disposed.
This discharge permit does not spec~cally dictate waste minimization conditions at this time. The Division
does strongly encourage the permittee fo continue working in developing and implementing a waste
minimization plan. Several industries have already developed plans and found that implementation resulted in
substantial savings. Both the Colorado Department of Public Health 8 Environment and EPA have information
and resources available. For more in-depth information, please contact these agencies.
