39 CFR Part 111

Domestic Mail Manual Changes for

First-Class Mail, Standard Mail, and

Bound Printed Matter Flats

AGENCY: Postal Service.

ACTION: Final rule.

SUMMARY: This final rule amends the

Domestic Mail Manual (DMM) to

implement the following mail

preparation standards: For First-Class

Mail, packages of Presorted rate flats

and packages of automation rate flats

that are part of the same mailing job and

reported on the same postage statement

must be co-trayed according to the

standards in DMM M910; For Standard

Mail, packages of Presorted rate flats

and packages of automation rate flats

that are part of the same mailing job and

reported on the same postage statement

must be co-sacked according to the

standards in DMM M910; For Standard

Mail, packages of Enhanced Carrier

Route flats and 5-digit packages of

Presorted flats must be sacked or

palletized using the labeling list L001

scheme sort. This includes the scheme

sorts included in the optional

preparation methods in DMM M920,

M930, and M940; and For Bound

Printed Matter, packages of Carrier

Route flats and 5-digit packages of

Presorted flats must be sacked or

palletized using the labeling list L001

scheme sort.

EFFECTIVE DATE: September 1, 2001.

FOR FURTHER INFORMATION CONTACT:

Anne Emmerth, 703–292–3641,

aemmerth@email.usps.gov.

SUPPLEMENTARY INFORMATION: On March

16, 2001 (66 FR 15206), the Postal

Service published in the Federal

Register a proposed rule seeking

comments on proposed changes to the

Domestic Mail Manual (DMM) that

would revise mail preparation standards

for flats. The original comment period

ended on April 13, 2001; as of that date,

no comments were received. On April

17, 2001 (65 FR 19740), the Postal

Service re-opened the comment period

through May 4 to allow customers more

time to comment on the proposed

changes. The Postal Service received

one comment.

Generally, the changes are intended to

align mail preparation more closely

with the way that the Postal Service

transports and processes flat-size mail.

The co-traying requirements for FirstClass Mail flats and the co-sacking

requirements for Standard Mail flats

will result in fewer less-than-full trays

and sacks and an overall reduction in

the number of trays and sacks prepared

by mailers and processed by the Postal

Service. For Presorted rate Standard

Mail, with sack-based rates, this

requirement also will result in lower

postage rates for some mail that will

move to a finer sack presort level.

Requiring the use of labeling list L001

for sacked carrier route Standard Mail

and Bound Printed Matter flats also will

result in fewer sacks prepared by

mailers. For mail on pallets, use of L001

will create more 5-digit level pallets,

resulting in fewer package handlings for

the Postal Service and better service for

mailers.

The changes are outlined below by

class of mail; the DMM language follows

at the end of this final rule.

In response to the proposed rule, the

Postal Service received one comment

from a large commercial printer. The

commenter expressed support for the

mail preparation changes in the

proposed rule and believes that these

changes will improve service and

handling of 5-digit containers and

reduce the number of sacks. The

commenter suggested that the proposed

September 1 implementation date be

moved to January 2002. The commenter

explained that in September the mailing

industry will be in the midst of

preparing its heaviest volumes for the

fall mailing season, which is not a

convenient time to implement new and

complex preparation standards.

The Postal Service appreciates

receiving supportive comments and

thanks the commenter for responding to

the proposed rule. The Postal Service

recognizes that mail preparation

changes can be disruptive to mailers

who must adjust presort software

systems and internal operations. The

standards in this final rule will result in

more efficient and cost-effective mail

handling for the Postal Service and

better service and postage savings for

mailers. Therefore, implementing these

changes on September 1 will allow the

Postal Service and its customers to

capture savings and efficiencies during

the time of heaviest mail volume.

Based on the comment received and

discussions with other mailers and

presort software vendors regarding these

changes, the Postal Service will

implement the standards in this final

rule on September 1, 2001. This will

allow time for programming, testing,

and installation of new presort software,

and time for mailers to adjust their

internal processes in advance of the fall

mailing season.

The changes implemented in this

final rule are as follows:

1. First-Class Mail

Required Co-Traying

Since January 7, 2001, mailers have

had the option to use M910 to co-tray

packages of Presorted rate flats and

automation rate flats that are part of the

same mailing job (see M130.1.6 and

M820.1.9). This final rule changes that

option into a requirement. Therefore,

effective September 1, 2001, any FirstClass Mail mailing job that contains

packages of Presorted rate flats and

packages of automation rate flats and is

28660 Federal Register / Vol. 66, No. 101 / Thursday, May 24, 2001 / Rules and Regulations

reported on a single postage statement

must be co-trayed using M910.1.0.

2. Standard Mail

a. Scheme Sort

Currently, Standard Mail Enhanced

Carrier Route flats are sorted to two

required sack levels and one optional

sort level (required carrier route,

optional 5-digit scheme carrier routes

using labeling list L001, and required 5-

digit carrier routes) (see M620.4.0). This

final rule changes the optional sort level

into a required sort level. Therefore,

effective September 1, 2001, all

Enhanced Carrier Route Standard Mail

flats must be sorted to all three required

sack levels (carrier route, 5-digit scheme

carrier routes, and 5-digit carrier routes).

Current M620.4.0 contains sack

preparation requirements for Standard

Mail Enhanced Carrier Route flats and

irregular parcels. In order to apply the

labeling list L001 scheme sort only to

flats, the sacking requirements for flats

have been separated into a different

section. Therefore, the sack preparation

requirements for irregular parcels are

included in this final rule only to show

renumbering and reorganization. There

are no mail preparation changes for

Standard Mail Enhanced Carrier Route

irregular parcels.

Currently, mailers have the option to

use the L001 scheme sort for packages

of Standard Mail Enhanced Carrier

Route flats and 5-digit packages of

Presorted flats on pallets (see M045.3.2).

This final rule changes the two optional

sort levels using labeling list L001 (5-

digit scheme carrier routes and 5-digit

scheme) into required sort levels.

Therefore, effective September 1, 2001,

packages of carrier route rate flats on

pallets must be sorted to 5-digit scheme

carrier routes pallets as the first sort

level, and 5-digit packages of Presorted

flats must be sorted to 5-digit scheme

pallets as the first sort level.

Under the advanced preparation

options in M920, M930, and M940,

mailers currently have the option of

sorting Standard Mail packages with or

without using the L001 scheme sort.

This final rule eliminates the ‘‘nonL001’’ sort (current M920.2.4, M920.2.6,

M930.2.4, and M940.2.4). Therefore,

effective September 1, 2001, mailers

sorting Standard Mail flats under M920,

M930, or M940 will be required to use

the L001 scheme sort.

These changes apply to regular and

nonprofit Standard Mail flats.

b. Required Co-Sacking

Since January 7, 2001, mailers have

had the option to use M910 to co-sack

packages of Presorted rate flats and

packages of automation rate flats that

are part of the same mailing job (see

M610.1.5 and M820.1.9). This final rule

changes that option into a requirement.

Therefore, effective September 1, 2001,

any Standard Mail mailing job that

contains packages of Presorted rate flats

and packages of automation rate flats

and is reported on a single postage

statement must be co-sacked using

M910.3.0.

These changes apply to regular and

nonprofit Standard Mail flats.

3. Bound Printed Matter

Scheme Sort

Currently, Bound Printed Matter

Carrier Route flats are sorted to two

required sack levels and one optional

sort level (required carrier route,

optional 5-digit scheme carrier routes

using labeling list L001, and required 5-

digit carrier routes) (see M723.2.3). This

final rule changes the optional sort level

into a required sort level. Therefore,

effective September 1, 2001, all Bound

Printed Matter carrier route flats must

be sorted to all three required sack

levels (carrier route, 5-digit scheme

carrier routes, and 5-digit carrier routes).

Currently, mailers have the option to

use the L001 scheme sort for packages

of Bound Printed Matter carrier route

flats and 5-digit packages of Presorted

flats on pallets (M045.3.3). This final

rule changes the two optional sort levels

(5-digit scheme carrier routes and 5-

digit scheme) into required sort levels.

Therefore, effective September 1, 2001,

packages of carrier route rate flats on

pallets must be sorted to 5-digit scheme

carrier routes pallets as the first sort

level, and 5-digit packages of Presorted

flats must be sorted to 5-digit scheme

pallets as the first sort level.

There are no other mail preparation

changes for Bound Printed Matter.

PAVE Certification

For mailings that are co-trayed or cosacked under M910, documentation

produced by PAVE-certified software or

standardized documentation under

P012 must be submitted with each

mailing job. Use of PAVE-certified

software is required for the advanced

‘‘merging’’ preparation options in M920,

M930, and M940, which include the

L001 scheme sort.

Implementation Date

The implementation date for these

changes is September 1, 2001. This date

allows presort software vendors time to

update and distribute software to their

customers and includes time for

installation and testing of the software.

j. A 5-digit/scheme carrier routes sort

for carrier route rate Periodicals flats

and irregular parcels (nonletters),

Enhanced Carrier Route rate Standard

Mail flats, and Carrier Route Bound

Printed Matter flats, prepared in sacks

or as packages on pallets yields a 5-digit

scheme carrier routes sack or pallet for

those 5-digit ZIP Codes listed in L001

and 5-digit carrier routes sacks or pallets

for other areas. The 5-digit ZIP Codes in

each scheme are treated as a single

presort destination subject to a single

minimum sack or pallet volume, with

no further separation by 5-digit ZIP

Code required. Sacks or pallets prepared

for a 5-digit scheme carrier routes

destination that contain carrier route

packages for only one of the schemed 5-

digit areas are still considered to be

sorted to 5-digit scheme carrier routes

and are labeled accordingly. The 5-digit/

scheme carrier routes sort is required for

carrier route packages of flat-size and

irregular parcel Periodicals, for

Enhanced Carrier Route Standard Mail

flats, and for Carrier Route Bound

Printed Matter flats. Preparation of 5-

digit scheme carrier routes sacks or

pallets must be done for all 5-digit

scheme destinations.

[Amend 1.3k to show that the scheme

sort is required for Standard Mail flats

and Bound Printed Matter flats.]

k. A 5-digit/scheme sort for

Periodicals flats and irregular parcels

(nonletters), Standard Mail flats, and

Presorted Bound Printed Matter flats

prepared as packages on pallets yields

5-digit scheme pallets containing

automation rate and Presorted rate 5-

digit packages for those 5-digit ZIP

Codes listed in L001 and yields 5-digit

pallets containing automation rate and

Presorted rate 5-digit packages for other

areas (automation rate packages are not

applicable to Bound Printed Matter).

The 5-digit ZIP Codes in each scheme

are treated as a single presort

destination subject to a single minimum

pallet volume, with no further

separation by 5-digit ZIP Code required.

Pallets prepared for a 5-digit scheme

destination that contain 5-digit packages

for only one of the schemed 5-digit areas

are still considered to be sorted to the

5-digit scheme and are labeled

accordingly. The 5-digit/scheme sort is

required for flat-size and irregular

parcel-size Periodicals, for Standard

Mail flats, and for Presorted Bound

Printed Matter flats. The 5-digit/scheme

sort may not be used for other mail

prepared on pallets, except for 5-digit

packages of Standard Mail irregular

parcels that are part of a mailing job that

is prepared in part as palletized flats at

automation rates. Preparation of 5-digit

scheme pallets must be done for all 5-

digit scheme destinations.

Mail flats.]

a. Periodicals, Standard Mail, and

Package Services (except for Parcel Post

mailed at BMC Presort, OBMC Presort,

DSCF, and DDU rates). A pallet must be

prepared to a required sortation level

when there are 500 pounds of

Periodicals, Standard Mail, or Package

Services mail in packages or sacks; 500

pounds of parcels; or six layers of

Periodicals or Standard Mail letter trays.

For packages of Periodicals flats and

irregular parcels and packages of

Standard Mail flats on pallets that are

prepared under the standards for

package reallocation to protect the SCF

pallet (M045.4.0), not all mail for a 5-

digit scheme carrier routes, 5-digit

scheme, 5-digit carrier routes, or 5-digit

pallet or for a merged 5-digit scheme,

merged 5-digit, or 3-digit pallet is

required to be on that corresponding

pallet level. For packages of Standard

Mail flats on pallets prepared under the

standards for package reallocation to

protect the BMC pallet (M045.5.0), not

all mail for a required ASF pallet must

be on an ASF pallet. Mixed ADC or

mixed BMC pallets of sacks, trays, or

machinable parcels, as appropriate,

must be labeled to the BMC or ADC (as

appropriate) serving the post office

where mailings are entered into the

mailstream. The processing and

distribution manager of that facility may

issue a written authorization to the

mailer to label mixed BMC or mixed

ADC pallets to the post office or

processing and distribution center

serving the post office where mailings

are entered. These pallets contain all

mail remaining after required and

optional pallets are prepared to finer

sortation levels under M045, as

appropriate.

4.0 PACKAGE REALLOCATION TO

PROTECT SCF PALLET FOR

PERIODICALS FLATS AND

IRREGULAR PARCELS AND

STANDARD MAIL FLATS ON

PALLETS

[Amend 4.1 to delete references to

optional sort levels.]

4.1 Basic Standards

Package reallocation to protect the

SCF pallet is an optional preparation

method (if performed, package

reallocation must be done for the

complete mailing job); only PAVEcertified presort software may be used to

create pallets under the standards in 4.2

through 4.4. The software will

determine if mail for an SCF service

area would fall beyond the SCF level if

all merged 5-digit scheme, 5-digit

scheme carrier routes, 5-digit scheme,

merged 5-digit, 5-digit carrier routes, 5-

digit, or 3-digit pallets are prepared.

Reallocation is performed only when

there is mail for the SCF service area

that would fall beyond the SCF pallet

level (e.g., to an ADC or BMC pallet).

The amount of mail required to bring

the mail that would fall beyond the SCF

level back to an SCF level is the

minimum volume that will be

reallocated, where possible.

Note: The current DMM combines the

preparation standards for flats and irregulars

into one section. Because the L001 scheme

sort will be required for flats but not for

irregulars, the current single section has been

split into two sections: one for flats and one

for irregulars. The standards for irregulars are

included in this final rule because they have

been renumbered and reorganized; however,

there are no changes to the mail preparation

for irregular parcels.

[Amend 4.0 to add the required L001

4.0 SACK PREPARATION—FLATS

4.1 Required Sack Minimums

A sack must be prepared when the

quantity of mail for a required presort

destination reaches either 125 pieces or

15 pounds of pieces, whichever occurs

first, subject to these conditions:

a. For identical-weight pieces, a

single-piece weight of 1.92 ounces (0.12

pound) results in 125 pieces weighing

15 pounds. Identical-weight pieces

weighing 1.92 ounces (0.12 pound) or

less must be prepared using the 125-

piece minimum; those that weigh more

must be prepared using the 15-pound

minimum.

b. For nonidentical-weight pieces,

mailers must either use the minimum

that applies to the average piece weight

for the entire mailing (divide the net

weight of the mailing by the number of

pieces; the resulting average singlepiece weight determines whether the

125-piece or 15-pound minimum

applies) or sack by the actual piece

count or mail weight for each sack, if

documentation can be provided with

the mailing that shows (specifically for

each sack) the number of pieces and

their total weight.

c. Mailers must note on the

whether they applied the 125-piece

(‘‘PCS’’) or 15-pound (‘‘WT’’) threshold

or the method in 4.1b (‘‘BOTH’’).

Revisions to the California and Arizona

State Implementation Plans, Antelope

and Maricopa County Environmental

Services Department

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Direct final rule.

SUMMARY: EPA is taking direct final

action to approve revisions to the

Antelope Valley Air Pollution Control

District (AVAPCD) and Maricopa

County Environmental Services

Department (MCESD) portions of the

respective California and Arizona State

Implementation Plans (SIPs). These

revisions concern volatile organic

compound (VOC) emissions from

solvent cleaning operations and

automotive windshield washer fluid

use. We are approving local rules that

regulate these emission sources under

the Clean Air Act as amended in 1990

(CAA or the Act).

DATES: This rule is effective on July 23,

2001 without further notice, unless EPA

receives adverse comments by June 25,

2001. If we receive such comment, we

will publish a timely withdrawal in the

Federal Register to notify the public

that this rule will not take effect.

ADDRESSES: Mail comments to Andy

I. The State’s Submittal

A. What Rules did the States Submit?

Table 1 lists the rules we are

approving with the dates that they were

adopted by the local air agencies and

submitted by the California Air

Resources Board (CARB) and Arizona

Department of Environmental Quality

(ADEQ).

TABLE 1.—SUBMITTED RULES

Local Agency Rule No. Rule Title Adopted Submitted

AVAPCD ..................... 1171 Solvent Cleaning Operations .............................................................................. 11/17/98 02/16/99

MCESD ....................... 344 Automotive Windshield Washer Fluid ................................................................. 04/07/99 08/04/99

On April 23, 1999 and August 25,

1999, these respective rule submittals

from the CARB and ADEQ were found

to meet the completeness criteria in 40

CFR part 51, appendix V, which must be

met before formal EPA review.

B. Are There Other Versions of These

Rules?

We approved a version of Rule 1171

into the California SIP on July 14, 1995.

The AVAPCD adopted revisions to the

SIP-approved version on November 17,

1998 and CARB submitted them to us

on February 16, 1999. There are no

previous versions of Rule 344 in the

Arizona SIP, although the MCESD

adopted an earlier version of this rule

on April 3, 1996, and ADEQ submitted

it to us on February 26, 1997. While we

can act on only the most recently

submitted version, we have reviewed

materials provided with previous

submittals.

C. What Is the Purpose of the Submitted

Rules?

These rules limit the emissions of

VOCs from solvent cleaning operations

and automotive windshield washer

fluid use. The TSDs have more

information about these rules.

II. EPA’s Evaluation and Action

A. How Is EPA Evaluating the Rules?

Generally, SIP rules must be

enforceable (see section 110(a) of the

Act), must require Reasonably Available

Control Technology (RACT) for major

sources in nonattainment areas (see

section 182(a)(2)(A)), and must not relax

existing requirements (see sections

110(l) and 193). The AVAPCD and

MCESD regulate ozone nonattainment

areas (see 40 CFR part 81). Rule 1171

must fulfill RACT; because Rule 344

does not apply to major sources, it is not

required to impose RACT.
