WAC 246-272A-0110
Proprietary treatment
products -- Certification and registration. (1) Manufacturers
shall register their proprietary treatment products with the
department before the local health officer may permit their
use.
(2) To qualify for product registration, manufacturers
desiring to sell or distribute proprietary treatment products
in Washington state shall:
(a) Verify product performance through testing using the
testing protocol established in Table I and register their
product with the department using the process described in WAC 246-272-0120;
(b) Report test results of influent and effluent sampling
obtained throughout the testing period (including normal and
stress loading phases) for evaluation of constituent reduction
according to Table II;
(c) Demonstrate product performance according to Table
III. All thirty-day averages and geometric means obtained
throughout the test period must meet the identified threshold
values to qualify for registration at that threshold level;
and
(d) For registration at levels A, B, and C verify
bacteriological reduction according to WAC 246-272A-0130.
(3) Manufacturers verifying product performance through
testing according to the following standards or protocols
shall have product testing conducted by a testing facility
accredited by ANSI:
(a) ANSI/NSF Standard 40 -- Residential Wastewater
Treatment Systems;
(b) NSF Standard 41: Non-Liquid Saturated Treatment
Systems;
(c) NSF Protocol P157 Electrical Incinerating Toilets - Health and Sanitation; or
(d) Protocol for bacteriological reduction described in
WAC 246-272A-0130.
(4) Manufacturers verifying product performance through
testing according to the following standards or protocols
shall have product testing conducted by a testing facility
meeting the requirements established by the Testing
Organization and Verification Organization, consistent with
the test protocol and plan:
(a) EPA/NSF -- Protocol for the Verification of Wastewater
Treatment Technologies; or
(b) EPA Environmental Technology Verification Program
protocol for the Verification of Residential Wastewater
Treatment Technologies for Nutrient Reduction.
(5) Treatment levels used in these rules are not intended
to be applied as field compliance standards. Their intended
use is for establishing treatment product performance in a
product testing setting under established protocols by
qualified testing entities.

30-day Average (for each month)
For bacteriological reduction performance, report fecal coliform test results
of influent and effluent sampling by geometric mean from samples drawn
within thirty-day or monthly calendar periods, obtained from a minimum of
three samples per week throughout the testing period. See WAC 246-272A-0130.
Test report must also include the individual results of all samples drawn
throughout the test period.
Category 2 Designed to treat
high-strength sewage when septic
tank effluent is anticipated to be
greater than treatment level E.
Report all individual test results and full test average values of influent and
effluent sampling obtained throughout the testing period for: CBOD5, TSS
and O&G. Establish the treatment capacity of the product tested in
pounds per day for CBOD5.
(Such as at restaurants, grocery
stores, mini-marts, group homes,
medical clinics, residences, etc.)
Category 3 Black water component
of residential sewage (such as
composting and incinerating
toilets).
Report test results on all required performance criteria according to the
format prescribed in the NSF test protocol described in Table I.
