Guidelines Establishing Test

Procedures for the Analysis of

Pollutants; Centralized Waste

Treatment and Landfills Point Source

Categories; Notice of Data Availability

and Request for Comment

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Notice of data availability and

request for comment.

SUMMARY: On January 13, 1999, EPA

proposed effluent limitations

guidelines, pretreatment standards, and

new source performance standards for

the Centralized Waste Treatment (CWT)

Point Source Category to limit effluent

discharges to waters of the United States

and the introduction of pollutants into

publicly owned treatment works. The

comment period for the proposal closed

on March 15, 1999.

In the CWT proposal, EPA noted

plans for a validation study for several

pollutants found during EPA’s data

gathering, using EPA Methods 625 and

1625. Today, EPA invites comment on

the validation data for the pollutants

included in the CWT proposal. EPA

plans to use these data to support the

use of EPA Methods 625 and 1625, as

amended, in the upcoming final CWT

rule, and to establish performance

criteria for the additional analytes. EPA

is soliciting comment only on the new

information and data being made

available today.

Today’s document also provides

notice that EPA will clarify the scope of

recently-published amendments to EPA

Methods 625 and 1625 for the Landfills

Point Source Category.

DATES: Submit an original and three

copies of your comments on or before

August 4, 2000.

ADDRESSES: Please send an original and

3 copies of your comments and

enclosures (including references) to
