Changes allowed:

 

Deschutes County Environmental Health Division made the determinations of which treatment standard the systems qualify for based on the information available to the County at the time the list was published.  If a vendor of an onsite wastewater treatment system wishes to be added to the list or change category, they may do so by supplying the appropriate third party data or report, justification statement for changing the category, and paying the Actual Cost of Service (ACS) rate for county staff to review the documentation and proposal.

 

Acceptable data sources to support changes include:  Third party data, and/or peer reviewed journal article(s)

 

Note:  NSF nitrogen reduction data may be pro-rated if influent waste strength is low.  Field test data is preferred.
