AES is approved in the western part of New York State on an area by area basis. Appendix 75-a, under the Specific Waivers (75-a.11) of the Wastewater Treatment Standards allows this. A designated full-time city, county or part-county health department official may issue a Specific Waiver, approving the design and installation of AES. When installed as a replacement system, AES may be be used throughout the State of New York. Be sure to check with your local approving authority.
