Foreword

T he Clean Water Act (CWA) was enacted to restore and maintain the chemical, physical, and biological

integrity of the nation's surface waters. This was to be done by reducing direct pollutant discharges into

waterways, financing municipal wastewater treatment facilities, developing technology necessary to eliminate the discharge of pollutants, and by managing polluted runoff. I n New York State, Article 17 of the Environmental Conservation Law (ECL), "Water Pollution

Control," was enacted to protect and maintain both surface and groundwater resources. It authorized the

creation of the State Pollutant Discharge Elimination System (SPDES)

Program to protect New York's

water resources. On-site Wastewater Treatment Systems (OWTS) may discharge to either surface water or groundwater. P

ursuant to Article 17 Title 7 of the ECL all OWTSs, without the admixture of industrial or other waste,

and with a groundwater discharge of 1,000 gallons per day or greater or a surface water discharge of any

size, must be covered by a SPDES permit issued by the New York State Department of Environmental

Conservation (NYSDEC).

D esign standards for large Publicly Owned Treatment Works (POTWs) have been updated independently by the Great Lakes-Upper Mississippi River Board of State and Provincial Public Health and Environmental Managers (GLUMRB) and the New England Interstate Water Pollution Control Commission (NEIWPCC). Design standards for small individual residential systems are updated by the New York State Department of Health (NYSDOH), local county health departments, or watershed organizations. These Design Standards for Intermediate

Sized Wastewater Treatment Systems (Design

Standards) are being updated by NYSDEC to meet the needs not addressed by the large and small systems design standards (refer to Appendix A for the applicable technical standard). Over the last 20

years OWTS technologies have increased in the level of treatment provided and in complexity of design

and operation. It is appropriate that the Design Standards are updated now to remain current with the needs of the wastewater treatment system design professionals. N umerous references to the GLUMRB's Recommended Standards for Wastewater Facilities, (Ten States Standards), 2004 and NEIWPCC's Guides for the Design of Wastewater Treatment Works -Technical Report-16, 2011 (TR-16), appear in this manual. Ten States Standards has been adopted by NYSDEC as

New York State's official standards for municipal wastewater treatment and collection facilities according

to 6 NYCRR Part 750-2.10.g.1. Ten States Standards may be viewed at: http://10statesstandards.com,

and is available in print from Health Education Service, Inc., P.O. Box 7126, Albany, New York 12224,

518-439-7286. Health Education Services (HES) may be accessed online at

http://www.healthresearch.org. TR-16 is also an acceptable design standard for municipal systems of any

size, or any non municipal, intermediate sized systems that treat only sanitary wastewater. TR-16

addresses standards for alternative collection systems such as vacuum sewers, low pressure/grinder pump

sewers, septic tank effluent (pump) and septic tank effluent (gravity) sewers (STEP/STEG). NYS DOH regulations for residential wastewater treatment systems discharging less than 1,000 gpd are entitled "Appendix 75-A, Wastewater Treatment Standards - Residential Onsite Systems." Design guidance for residential onsite systems are published under the title

Residential Onsite Wastewater

Treatment Systems Design Handbook. The NYSDOH Design Handbook is available from HES, Inc. http://www.healthresearch.org). Both documents are on the NYSDOH website. ii
