  General Information: Onsite Sewage Disposal System (OSDS) Program Back BWPC Home Page   

Onsite Sewage Disposal Systems (OSDS) are defined in Nevada's regulation (NAC 445A.9556) as "any existing or proposed on-site system for the treatment and disposal of domestic sewage, including, without limitation, a standard subsurface, alternative or experimental sewage disposal system that may include a treatment unit and an effluent absorption system." It includes a Class V well under subsection 10 of NAC 445A.849. OSDS does not include an individual sewage disposal system as defined in NAC 444.764, a package plant for sewage treatment as defined in NRS 445A.380, or a system designed to treat and dispose of industrial waste.

OSDS permits are required for certain activities by US EPA regulations at 40 CFR 144. In compliance with this regulation, the Nevada Division of Environmental Protection (NDEP) has developed the OSDS permitting program for onsite sewage disposal systems. Subsurface discharges of treated wastewater associated OSDS would be covered under the general permit GNEVOSDS09.



Note: The onsite collection and temporary holding of domestic sewage from commercial operations are permitted under the Holding Tank general permits: Temporary Holding Tank (GNEVTHT09) and Permanent Holding Tank (GNEVPHT09).

User Instructions - We suggest users read the fact sheet and the general permit listed below and related information to determine if your activity would be covered under the Onsite Sewage Disposal System General permit (GNEVOSDS09). Depending the complexity of the OSDS plan, the Administrator of the Division may require an applicant to obtain an individual permit, as allowed for under NRS 445A.480. In such cases, the applicant may apply for an Individual Discharge Permit.

If you are subject to the OSDS General Permit requirements, please complete a Notice of Intent (NOI) to seek coverage under the General Permit GNEVOSDS09 by completing the form (see below.) After completing the form you will need to print this document and mail it, along with all other pertinent information to NDEP at the address indicated. Application and annual fees for the general and individual OSDS permits are listed below.

Note: Nevada regulations require all its Onsite Sewage Disposal Systems to be designed by a registered Nevada professional engineer (P.E.). All plans and calculations shall be wet stamped by the engineer, and the engineer shall be responsible for certifying installation in writing.

Construction and operation of Onsite Sewage Disposal System (OSDS) as defined under statutes (NRS 445A) and regulations (NAC 445A.950 thru 445A.9706).This program includes the installation and operation of septic systems and similar systems in commercial properties.
