As new treatment technologies are introduced, or as new regulations make different treatment technologies more advantageous, there is a need for states to share their expertise and experiences with each other. One state’s “cutting edge” technology may be another state’s “tried and true”. A state facing a new technology for the first time will be able to benefit from another state that has already approved the process or has practical experience with the technology in the field. Even where there is no prior experience to draw on, states working together can more easily identify outside experts in EPA, academia, consultants, or equipment manufacturers.
