Note for Andy McDaniel
From: Carla Sanderson
Date: Thu, Dec 7, 1995 12:54 PM
Subject: RE: Multipliers based on BODu tests
To: Andy McDaniel
Fourth Creek: I would take a look at the % of industrial waste and types of industries that are
connected to the plant. We can take a look at Farrell's BOD database to see if there are
BODLT on any industries or municipalities that have similar wastes.
Third Creek: Before using a LT test for your model, you -may want to check the date of the
test and % industrial at the time of the test and make sure the facility has the same or very
similar waste make-up now. SOP is currently being worked on for using Lont Term data
that wll go over the steps to take in order to figure out what numbers should be used for your
analysis.
If you have any further questions, please let me know.

Subject Multipliers based on BODu tests
To: Carla Sanderson
Carla,
Statesville's Third Ck. WWTP has had an BODu test run that rve used to calculate a
multiplier. However, BODu info is not available for Statesville's Fourth Ck. facility (at least
I didn't see a test in the BODu notebook). The Third Ck multiplier is 3.2 which will weigh
against Third Ck more heavily than the default 2 multiplier for Fourth Ck.
What would you recommend using as the multiplier for Fourth Ck.?
