serve as proof of compliance with this condition. -

4. In accordance with Division policy, a minimum c>jorine contact time of 30 minutes shall be
provided for the treated wastewater for disinfection prior to its transference to the spray
field. The engineer shall evaluate the need for baffles in the 3,000 gallon storage/pump
tank, or any other design criteria which may be necessary to provide the minimum contact
time. This evaluation (and any resulting design changes) should be submitted to the
Division with the engineer's certification.
5. The spray irrigation facilities shall be effectively maintained and operated at all times so that
there is no discharge to the surface waters, nor any contamination of ground waters which
will render them unsatisfactory for normal use. In the event that the facilities fail to
perform satisfactorily, including the creation of nuisance conditions or failure of the
irrigation area to adequately assimilate the wastewater, the Permittee shall take immediate
corrective actions including those actions that may be required by the Division of
Environmental Management, such as the construction of additional or replacement
wastewater treatment and disposal facilities.

method will have a ilow rata varying from Iwo to eight gallons per minule per square loot and may be either upllow or downflow carbon beds. Carbon may :
may not ba reganeraled on the waslowaler treatment plant site;
(2) Aerated Lagoons. A basin in which all solids are maintained in suspension and by which biological oxidation or organic mailer is reduced through ani!iciall
accelerated transfer of oxygen on a flow-through basis;
(3) Asration- A process of bringing about Intimate contact balween air or high puftiy oxygen in a liquid by spraying, agitation or diyusion;(3a) Extended
