    94. Amend Method 306 of Appendix A to Part 63 by revising Sections
2.2.1, 6.1.4, and 8.0 to read as follows:

Appendix A to Part 63--Test Methods Pollutant Measurement Methods From
Various Waste Media

Hard Chromium Electroplating and Chromium Anodizing Operations--
Isokinetic Method

    2.2.1 Total chromium samples with high chromium concentrations
(>=35 [micro]g/L) may be analyzed using inductively coupled plasma
emission spectrometry (ICP) at 267.72 nm. Note: The ICP analysis is
applicable for this method only when the solution analyzed has a Cr
concentration greater than or equal to 35 [micro]g/L or five times
the method detection limit as determined according to Appendix B in
40 CFR part 136. Similarly, inductively coupled plasma-mass
spectroscopy (ICP-MS) may be used for total chromium analysis
provided the procedures for ICP-MS analysis described in Method 6020
or 6020A (EPA Office of Solid Waste, publication SW-846) are
followed.
* * * * *
    6.1.4 Operating and maintenance procedures for the sampling
train are described in APTD-0576 of Method 5. Users should read the
APTD-0576 document and adopt the outlined procedures. Alternative
mercury-free thermometers may be used if the thermometers are, at a
minimum, equivalent in terms of performance or suitably effective
for the specific temperature measurement application.
* * * * *

8.0 Sample Collection, Preservation, Holding Times, Storage, and
Transport

    Note:  Prior to sample collection, consideration should be given
to the type of analysis (Cr \+6\ or total Cr) that will be
performed. Which analysis option(s) will be performed will determine
which sample recovery and storage procedures will be required to
process the sample.

* * * * *

    95. Amend Method 306A of Appendix A to Part 63 by revising Section
8.2 to read as follows:

Method 306A--Determination of Chromium Emissions From Decorative and
Hard Chromium Electroplating and Chromium Anodizing Operations

* * * * *
    8.2 Sample Recovery. After the train has been transferred to the
sample recovery area, disconnect the tubing that connects the jar/
impingers. The tester shall select either the total Cr or Cr \+6\
sample recovery option. Samples to be analyzed for both total Cr and
Cr \+6\ shall be recovered using the Cr \+6\ sample option (Section
8.2.2). Note: Collect a reagent blank sample for each of the total
Cr or the Cr \+6\ analytical options. If both analyses (Cr and Cr
\+6\) are to be conducted on the samples, collect separate reagent
blanks for each analysis. Also, since particulate matter is not
usually present at chromium electroplating and/or chromium anodizing
operations, it is not necessary to filter the Cr \+6\ samples unless
there is observed sediment in the collected solutions. If it is
necessary to filter the Cr \+6\ solutions, please refer to Method
0061, Determination of Hexavalent Chromium Emissions from Stationary
Sources, Section 7.4, Sample Preparation in SW-846 (see Reference
1).

    96. Amend Method 308 of Appendix A to Part 63 by revising Section
10.1.3 to read as follows:

Method 308--Procedure for Determination of Methanol Emission From
Stationary Sources

* * * * *
    10.1.3 Temperature Sensors. Calibrate against mercury-in-glass
thermometers. An alternative mercury-free thermometer may be used if
the thermometer is, at a minimum, equivalent in terms of performance
or suitably effective for the specific temperature measurement
application.
* * * * *

    97. Amend Method 315 of Appendix A to Part 63 by revising Sections
6.1.1 and 10.5 and by redesignating Section 8.11 as 8.1 and revising
newly designated section 8.1 to read as follows:

Method 315--Determination of Particulate and Methylene Chloride
Extractable Matter (MCEM) From Selected Sources at Primary Aluminum
Production Facilities

    6.1.1 Sampling train. A schematic of the sampling train used in
this method is shown in Figure 5-1, Method 5, 40 CFR part 60,
Appendix A. Complete construction details are given in APTD-0581
(Reference 2 in section 17.0 of this method); commercial models of
this train are also available. For changes from APTD-0581 and for
allowable modifications of the train shown in Figure 5-1, Method 5,
40 CFR part 60, Appendix A, see the following subsections. Note: The
operating and maintenance procedures for the sampling train are
described in APTD-0576 (Reference 3 in section 17.0 of this method).
Since correct usage is important in obtaining valid results, all
users should read APTD-0576 and adopt the operating and maintenance
procedures outlined in it, unless otherwise specified herein.
Alternative mercury-free thermometers may be used if the
thermometers are, at a minimum, equivalent in terms of performance
or suitably effective for the specific temperature measurement
application. The use of grease for sealing sampling train components
is not recommended because many greases are soluble in methylene
chloride. The sampling train consists of the following components:

    8.1 Pretest preparation. It is suggested that sampling equipment
be maintained according to the procedures described in APTD-0576.
Alternative mercury-free thermometers may be used if the
thermometers are at a minimum equivalent in terms of performance or
suitably effective for the specific temperature measurement
application.

    10.5 Temperature sensors. Use the procedure in Section 10.3 of
Method 2, 40 CFR part 60, Appendix A to calibrate in-stack
temperature sensors. Dial thermometers, such as are used for the DGM
and condenser outlet, shall be calibrated against mercury-in-glass
thermometers. An alternative mercury-free thermometer may be used if
the thermometer is, at a minimum, equivalent in terms of performance
or suitably effective for the specific temperature measurement
application.

    98. Amend Method 316 of Appendix A to Part 63 by revising Section
10.5 to read as follows:

Method 316--Sampling and Analysis for Formaldehyde Emissions From
Stationary Sources in the Mineral Wool and Wool Fiberglass Industries

* * * * *
    10.5 Temperature gauges: Use the procedure in Section 4.3 of EPA
Method 2 to calibrate in-stack temperature gauges. Dial
thermometers, such as are used for the dry gas meter and condenser
outlet, shall be calibrated against mercury-in-glass thermometers.
An alternative mercury-free thermometer may be used if the
thermometer is, at a minimum, equivalent in terms of performance or
suitably effective for the specific temperature measurement
application.

definition for the term ``Df'' after equation (2) in Section
