part 58 were proposed on August 18,

1994 (59 FR 42541) to address the

application, siting, and operational

quality assurance of open path

analyzers, and supplemental quality

assurance guidance is in preparation.

Until these regulatory amendments are

promulgated and the supplemental

guidance for open path analyzers is

available, monitoring agencies

interested in using these methods

should contact the U.S. EPA for interim

guidance pertaining to network design,

siting, and quality assurance issues. The

EPA contact person for information on

these issues is Ms. Lee Ann B. Byrd,

Monitoring and Quality Assurance

Group, Office of Air Quality Planning

and Standards, telephone number (919)

541–5367.

Vendor modifications of a designated

method used for purposes of part 58 are

permitted only with prior approval of

EPA, as provided in part 53. Provisions

concerning modification of such

methods by users are specified under

section 2.8 of appendix C to 40 CFR part

58 (Modifications of Methods by Users).

In general, one of these designations

will apply to any analyzer which is

identical to the analyzer described in

the designation. In some cases, similar

analyzers manufactured prior to the

designation may be upgraded (e.g., by

minor modification or by substitution of

a new operation or instruction manual)

so as to be identical to the designated

method and thus achieve designation

status at a modest cost. The

manufacturer should be consulted to

determine the feasibility of such

upgrading.

Part 53 requires that sellers of

designated methods comply with

certain conditions. These conditions are

given in 40 CFR 53.9 and are

summarized below:

(1) A copy of the approved operation

or instruction manual must accompany

the analyzer when it is delivered to the

ultimate purchaser.

(2) The analyzer must not generate

any unreasonable hazard to operators or

to the environment.

(3) The analyzer must function within

the limits of the performance

specifications given in table B–1 of part

53 for at least one year after delivery

when maintained and operated in

accordance with the operation manual.

(4) Any analyzer offered for sale as a

reference or equivalent method must

bear a label or sticker indicating that it

has been designated as a reference or

equivalent method in accordance with

part 53.

(5) If such an analyzer has two or

more selectable ranges, the label or

sticker must be placed in close

proximity to the range selector and

indicate which range or ranges have

been included in the reference or

equivalent method designation.

(6) An applicant who offers analyzers

for sale as reference or equivalent

methods is required to maintain a list of

ultimate purchasers of such analyzers

and to notify them within 30 days if a

reference or equivalent method

designation applicable to the analyzers

has been canceled or if adjustment of

the analyzers is necessary under 40 CFR

53.11(b) to avoid a cancellation.

(7) An applicant who modifies an

analyzer previously designated as a

reference or equivalent method is not

permitted to sell the analyzer (as

modified) as a reference or equivalent

method (although he may choose to sell

it without such representation), nor to

attach a label or sticker to the analyzer

(as modified) under the provisions

described above, until he has received

notice under 40 CFR 53.14(c) that the

original designation or a new

designation applies to the method as

modified or until he has applied for and

received notice under 40 CFR 53.8(b) of

a new reference or equivalent method

determination for the analyzer as

modified.

Aside from occasional breakdowns or

malfunctions, consistent or repeated

noncompliance with any of these

conditions should be reported to:

Director, Atmospheric Research and

Exposure Assessment Laboratory,

Department E (MD–77), U.S.

Environmental Protection Agency,

Research Triangle Park, North Carolina

27711.

Designation of these equivalent

methods is intended to provide

assistance to the States in establishing

and operating their air quality

surveillance systems under part 58.

Technical questions concerning the

method should be directed to the

distributor. Additional information

concerning this action may be obtained

from Frank F. McElroy, Methods

Research and Development Division

(MD–77), Atmospheric Research and

Exposure Assessment Laboratory, U.S.

Environmental Protection Agency,

Research Triangle Park, North Carolina

27711, (919) 541–2622.

Henry L. Longest II,

Acting Assistant Administrator for Research

and Development.
