turning chambers and flowing foam solution down outside of tank.
[b.
Test all hose lines by full flow of foam solution for at least 60
seconds.]
[c.
Test monitor nozzles by full flow of water.]
The manufacturer's representative shall test samples of foam solution taken
from each system to ensure proper AFFF concentration. Provide protection
for all electrical fixtures and equipment exposed to possible damage during
tests and take necessary steps to prevent soil erosion [and contain runoff]
during testing.
3.8.2.3
Flushing and Rinsing
After completion of tests flush all piping carrying AFFF concentrate and
solution with fresh water. Piping normally containing AFFF concentrate
when the system is in standby mode need not be flushed. Rinse with fresh
water all equipment and surfaces exposed to AFFF discharge.
3.8.3
**************************************************************************
NOTE: Consult facility and the Division or District
environmental officials to determine local
requirements for containment and disposal of
discharged AFFF. In sufficient concentrations, AFFF
may cause disruption of processes in sewage
treatment plants and damage to fisheries. Edit the
paragraph as appropriate.
**************************************************************************
Provide temporary measures to prevent AFFF from entering storm drains,
[sanitary sewers,] drainage ditches, streams and water courses. [Do not
allow AFFF concentrate or solution to come in contact with earth. Contain
all discharged AFFF on paved surfaces or in tanks.] [Collect all
discharged AFFF and rinse and flushing water and dispose of it in an EPA -
approved waste-water treatment facility which provides secondary
(biological) treatment]. At least 15 days prior to the date flow testing
is to take place, submit written plan for AFFF containment [and disposal]
methods(s) to the Contracting Officer for approval.
3.8.4
Additional Tests
When deficiencies, defects or malfunctions develop during the tests
required, all further testing of the system shall be suspended until proper
adjustments, corrections or revisions have been made to assure proper
performance of the system. If these revisions require more than a nominal
delay, the Contracting Officer shall be notified when the additional work
has been completed, to arrange a new inspection and test of the system. All
tests required shall be repeated prior to final acceptance, unless directed
otherwise.
3.8.5
AFFF Concentrate Storage Tanks Fill-Up
**************************************************************************
NOTE: Consult facility to determine whether the
Government or the Contractor will furnish the
initial fill-up of AFFF concentrate.
