Completing Industrial Waste

Surveys (IWS)By Brian Allen

A pretreatment program is an EPA-mandated program that requires the Control

Authority to control industrial and commercial discharges to the sewer

collection and treatment system, thereby reducing the amount of pollutants

released to the environment from the wastewater treatment plant.

The Industrial Waste Survey (IWS) is a required part of the pretreatment

program. The IWS is conducted primarily to identify the nature and quantity of

pollutants entering the Publicly Owned Treatment Works.

40 CFR 403.8 (f) (2) (i) Identify and locate all possible IUs

(ii) Identify the character and volume of pollutants(iii) Notify IUs of applicable PT standards

PURPOSE

Investigating your Collection SystemTo protect your POTW

The Industrial Waste Survey (IWS) or may be referred as permit application is

the effort made to ensure that the POTW's list of Industrial Users and the

pollutants in their wastestream are current, and to determine which, if any, of

the Users have the potential to adversely affect the WWTP and its receiving

environments and should become Significant Industrial Users (SIU), or

otherwise might need regulation as a non-SIU.

Industrial Waste Survey (IWS)

The Significant Industrial User criteria are found in EPA 40 CFR 403 Pretreatment Standards and are listed below.An Industrial User is a SIU if the facility:• Discharges an average of 25,000 gallons or more per day of process wastewater

to the POTW (excluding sanitary, noncontact cooling and boiler blowdown wastewaters) or;

• Contributes more than 5 percent of the NPDES or non-discharge permitted flow limit or organic capacity of the POTW treatment plant (In this context, organic capacity refers to BOD, TSS and ammonia), or;

• Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471, or;

• Is, regardless of Parts (1), (2), and (3) above, otherwise determined by the control authority to have a reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement or POTW's receiving stream standard, or to limit the POTW's sludge disposal options.

Providing False Information

Western Massachusetts Power Plant Owner and Management Companies Sentenced

for Tampering and False Reporting.

Settlement requires companies to pay fines and payments totaling over $7 million .

BOSTON – Berkshire Power Company (BPC) and Power Plant Management Services, Inc.

(PPMS) were sentenced in U.S. District Court in Springfield for tampering with air

pollution emissions equipment, and PPMS was also sentenced for submitting false

information to both environmental and energy regulators relating to the

Berkshire Power Plant (“the Plant”) in Agawam, Mass.

During the course of the tampering investigation, criminal investigators also learned that

PPMS made and caused staff at the Plant to make false statements to the ISO-New

England, about the Plant’s availability to produce power for the New England grid. They

also caused staff at the Plant to falsely claim to the ISO that the Plant was available to

produce power when it was not. PPMS did this to maximize the Plant’s revenues and to

minimize repair expenditures.
