The municipal utility shall regularly use meters
or devices or methods for determining waste quantities (volumes) directly
or by differentials or otherwise and make tests and use other means
for determining the quality and other characteristics of all sewerage,
industrial wastes or other wastes discharged into the county sewer
system.
All measurements, tests and analyses of the
characteristics of sewerage and wastes to which reference is made
in these rules and regulations shall be determined in accordance with
the latest edition of Standard Methods for the Examination of Water
and Wastewater, as prepared, approved and published jointly by the
American Health Association, the American Water Works Association
and the Water Pollution Control Federation, or other reference sources
as specified by regulatory agency requirements, such as Methods for
Chemical Analysis of Water and Wastes, published by the USEPA. Sampling
shall be carried out in accordance with the customarily accepted methods
such as to reflect the effect of the constituents upon the county
sewer system and to determine the existence of any hazards. Volume
determination shall be conducted in accordance with sound engineering
practice.
In the event that the volume and/or pollutant concentration of the waste discharged to the county sewer system as determined under §§
227-19 and
227-20 of this article is disputed by a user, a program of resampling and gauging with subsequent chemical determination may be instituted as follows:
A. The user may submit a written request for resampling
and gauging of the waste to the Chief Engineer. Upon receipt of such
request, the municipal utility will conduct the necessary test. The
user shall confer with representatives of the municipal utility in
order that agreement may be reached as to the various factors which
must be considered in a new sampling program; or
B. The user may, at his own expense, employ a consultant
or agency of recognized professional standing to conduct a resampling
and reanalysis program, under the direction of the Chief Engineer
and for a period of time to be specified by the Chief Engineer. The
results of the resampling and the reanalysis shall be considered to
be the current analysis of the user's waste. In all cases, the determination
of the municipal utility, whether or not modified after resampling
and reanalysis as provided for in this section, shall be final as
regards to volume or pollutant concentrations.
