Process
Step 1
State the
problem.
Step 2
Identify the goals
of the study
Step 3
Identify
information
inputs
Step 4
Define the study
boundaries
Response
Spent wash water generated from the washing activities will be treated and then
discharged if treated water meets the Sunnyvale Publicly Owned Treatment Works
(POTW) discharge requirement.
Are the treated spent wash water concentrations less than or equal to the Sunnyvale
POTW limits (see Worksheet 15)?
Water samples will be collected and analyzed in accordance with the Sunnyvale POTW
discharge requirements.
This project is anticipated to begin field work in June 2010 and the estimated date of
completion is August 2011.
Step 5
Develop the
analytic approach
If treated spent wash water is above the Sunnyvale POTW limits, then it will be retreated
until it meets the discharge limits.
If treated spent wash water is below the Sunnyvale POTW limits, then it will be
discharged to the Sunnyvale treatment plant.
Step 6
Specify
performance or
acceptance
criteria
Step 7
Develop the plan
for obtaining the
data
Sunnyvale POTW limits are presented in Worksheet 15. Limits for additional disposal
facilities will be included upon procurement.
Laboratory data will be developed using EPA protocols, and the reported data will be
evaluated.
To minimize error, samplers will be trained and samples will be collected in accordance
with field sampling procedures describes in this SAP.
The laboratories will be evaluated by the NFESC or will hold the DoD ELAP certification,
and the California Department of Public Health ELAP certification (for methods certified
by California). Laboratory SOPs will comply with the DoD QSM version 4.1.
A waste water sample will be collected per every 120,000 gallons of treated spent wash
water.
