39 CFR Part 111


Proposed Domestic Mail Manual Changes for First-Class Mail, 
Standard Mail, and Bound Printed Matter Flats

AGENCY: Postal Service.

ACTION: Proposed Rule; reopening of comment period.

-----------------------------------------------------------------------

SUMMARY: The Postal Service is seeking comments on the following 
proposed mail preparation changes to the Domestic Mail Manual (DMM): 
Packages of First-Class Mail Presorted rate flats and automation rate 
flats that are part of the same mailing job would be required to be co-
trayed according to the standards in M910; packages of Standard Mail 
Presorted rate flats and automation rate flats that are part of the 
same mailing job would be required to be co-sacked according to the 
standards in M910; Standard Mail Enhanced Carrier Route and 5-digit 
flats would be required to be sacked or palletized using the labeling 
list L001 scheme sort (including the scheme sorts included in the 
optional preparation methods in M920, M930, and M940); and Bound 
Printed Matter Carrier Route and 5-digit flats would be required to be 
sacked or palletized using the labeling list L001 scheme sort.

DATES: Comments must be received on or before May 4, 2001.

ADDRESSES: Send written comments to the Manager, Mail Preparation and 
Standards, US Postal Service, 1735 N Lynn Street, Rm 3025, Arlington, 
VA 22209-6038. Written comments may be submitted via fax at 703-292-
4058. Copies of all written comments are available via fax or mail by 
calling Anne Emmerth at the number listed below.

FOR FURTHER INFORMATION CONTACT: Anne Emmerth, 703-292-3641, 
[email protected].

SUPPLEMENTARY INFORMATION: The Postal Service is extending the comment 
period on proposed changes to the Domestic Mail Manual (DMM) that would 
change mail preparation standards for flats. The changes themselves are 
outlined below by class of mail; the proposed DMM language follows at 
the end of this proposed rule. The proposed implementation date for 
these standards is September 1, 2001.
    This proposed rule was published previously in the Federal Register 
on March 16, 2001 (66 FR 15206); the original comment period ended on 
April 13, 2001. As of that date, no comments were received. As a 
convenience, the entire text of the proposed rule is reproduced here.
    Generally, the changes in this proposed rule are intended to align 
mail preparation more closely with the way that the Postal Service 
transports and processes flat-sized mail. The co-traying requirements 
for First-Class Mail flats and the co-sacking requirements for Standard 
Mail flats should 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 may also 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 should create more 5-digit 
level pallets, resulting in fewer package handlings for the Postal 
Service and better service for mailers.
    The changes proposed are as follows:

1. First-Class Mail

Required Co-Traying

    Currently, mailers have 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 (current M130.1.6 and M820.1.9). This proposal would 
make the current option a requirement. If this proposal is adopted, any 
First-Class Mail mailing job that contains packages of Presorted rate 
flats and packages of automation rate flats 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, and required 5-digit 
carrier routes under M620.4.0). This proposal would make the optional 
5-digit scheme carrier routes sort level (using labeling list L001) a 
required level. If this proposal is adopted, all Enhanced Carrier Route 
Standard Mail flats would be required to be sorted to all three sack 
levels.
    Current M620.4.0 contains sack preparation requirements for 
Standard Mail Enhanced Carrier Route flats and irregular parcels. In 
order to apply the 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 proposed rule only to show renumbering and 
reorganization.

[[Page 19741]]

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 
Standard Mail Enhanced Carrier Route flats on pallets (M045.3.2). This 
proposal would make the two optional sort levels (5-digit scheme 
carrier routes and 5-digit scheme using labeling list L001) required 
sort levels. If this proposal is adopted, all packages of Standard Mail 
carrier route rate flats on pallets would be required to be sorted to 
5-digit scheme carrier routes pallets and 5-digit scheme pallets as the 
first two sort levels.
    Under the advanced preparation options in current M920, M930, and 
M940, mailers have the option of sorting with or without using the L001 
scheme sort. This proposal would eliminate the ``non-L001'' sort 
(current M920.2.4, M920.2.6, M930.2.4, and M940.2.4). If this proposal 
is adopted, mailers sorting Standard Mail flats under M920, M930, or 
M940 will be required to use the L001 scheme sort.
    These proposed changes apply to regular and nonprofit Standard Mail 
flats.

b. Required Co-Sacking

    Currently, mailers have 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 (current M610.1.5 and M820.1.9). This 
proposal would require mailers to co-sack those packages. If this 
proposal is adopted, any Standard Mail mailing job that contains 
packages of Presorted rate flats and packages of automation rate flats 
must be co-sacked using M910.3.0.
    These proposed 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, and required 5-digit 
carrier routes under M723.2.3). This proposal would make the optional 
5-digit scheme carrier routes sort level (using labeling list L001) a 
required level. If this proposal is adopted, all Bound Printed Matter 
Carrier Route flats would be required to be sorted to all three sack 
levels.
    Currently, mailers have the option to use the L001 scheme sort for 
Bound Printed Matter packages of carrier route and 5-digit flats on 
pallets (M045.3.3). This proposal would make the two optional sort 
levels (5-digit scheme carrier routes and 5-digit scheme using labeling 
list L001) required sort levels. If this proposal is adopted, all 
packages of Bound Printed Matter carrier route rate flats on pallets 
would be required to be sorted to 5-digit scheme carrier routes 
pallets, and all 5-digit packages would be required to be sorted to 5-
digit scheme pallets as the first sort level.

PAVE Certification

    PAVE-certified software is not required to sort Standard Mail and 
Bound Printed Matter flats using labeling list L001. For mailings that 
are co-trayed or co-sacked 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.

Proposed Implementation Date

    The proposed 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 also includes time for 
installation and testing of the software. Commenters are welcome to 
comment on the proposed implementation date, and should include 
specific reasons why this date is or is not feasible.
    Although exempt from the notice and comment requirements of the 
Administrative Procedure Act (5 U.S.C. 553(b), (c)) regarding proposed 
rulemaking by 39 U.S.C. 410(a), the Postal Service invites comments on 
the following proposed revisions to the Domestic Mail Manual, 
incorporated by reference in the Code of Federal Regulations. See 39 
CFR Part 111.

    2. Revise the following sections of the Domestic Mail Manual (DMM) 
as set forth below:

Domestic Mail Manual

M  Mail Preparation and Sortation

M000  General Preparation Standards

M011  Basic Standards

1.0  TERMS AND CONDITIONS

1.3  Preparation Instructions

    For the purposes of preparing mail:
* * * * *
[Amend 1.3j to show that the L001 scheme sort is required for Standard 
Mail Enhanced Carrier Route flats and Bound Printed Matter Carrier 
Route flats:]

    j. A 5-digit/scheme carrier routes sort for carrier route rate 
Periodicals flats and irregular parcels, 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 5-digit scheme carrier routes sorted 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, Standard Mail flats, and 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

[[Page 19742]]

destination that contain 5-digit packages for only one of the schemed 
5-digit areas are still considered 5-digit scheme sorted 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 
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.

5.0  PREPARATION

5.2  Required Preparation

    These standards apply to:

[Amend item a to show that the L001 scheme sort is required for 
Standard Mail.]

    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, or 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 is required to 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.
* * * * *

5.6  Mail on Pallets

    These standards apply to mail on pallets:
* * * * *
[Amend item g to read as follows:]

    g. For nonletter-size Periodicals, Standard Mail flats, and Bound 
Printed Matter flats, packages of carrier route rate mail must be 
prepared on separate 5-digit pallets from automation and Presorted rate 
mail. Exception: For Periodicals and Standard Mail, under the standards 
in M920, M930, and M940, carrier route rate, automation rate, and 
Presorted rate packages can be combined onto the same merged 5-digit 
scheme pallet and merged 5-digit pallet for applicable 5-digit ZIP 
Codes.

flats.]

    Mailers must prepare pallets in the sequence listed below, except 
that mailings of sacks on pallets, trays on pallets, and irregular 
parcels must be prepared beginning with 3.2c (because L001 scheme sort 
is not permitted). Pallets must be labeled according to the Line 1 and 
Line 2 information listed below and under M031. At the mailer's option, 
Standard Mail flats prepared as packages on pallets may be palletized 
in accordance with the advanced presort options in M920, M930, or M940.
    a. 5-Digit Scheme Carrier Routes. Required for packages of flats on 
pallets. Not permitted for sacks or trays on pallets, or for irregular 
parcels on pallets except under M011. May contain only carrier route 
rate packages for the same 5-digit scheme under L001. Scheme sort must 
be done for all 5-digit scheme destinations. For all 5-digit 
destinations that are not part of a scheme, prepare 5-digit carrier 
routes pallets under 3.2c.
    (1) Line 1: use L001, Column B.
    (2) Line 2: ``STD FLTS''; followed by ``CARRIER ROUTES'' or ``CR-

    c. 5-Digit Carrier Routes. Required for sacks and packages; 
optional for trays. May contain only carrier route rate mail for the 
same 5-digit ZIP Code.
    (1) Line 1: use city, state abbreviation, and 5-digit ZIP Code 
destination (see M031 for military mail).
    (2) Line 2: ``STD FLTS'' or ``STD IRREG'' or, for trays on pallets 
only, ``STD LTRS'' as applicable; followed by ``CARRIER ROUTES'' or 
``CR-RTS.''
    d. 5-Digit. Required for sacks and packages; optional for trays. 
May contain only automation rate and/or Presorted rate mail for the 
same 5-digit ZIP Code.
    (1) Line 1: use city, state abbreviation, and 5-digit ZIP Code 
destination (see M031 for military mail).

[Amend the introduction to 3.3 and 3.3a through 3.3d to show that the 
scheme sort using L001 is required for packages of Bound Printed Matter 
flats.]

    Mailers must prepare pallets in the sequence listed below, except 
that mailings of sacks on pallets must be prepared beginning with 3.3c 
(because L001 scheme sort is not permitted). Pallets must be labeled 
according to the Line 1 and Line 2 information listed below and under 
M031.
    a. 5-Digit Scheme Carrier Routes. Required for packages of flats on 
pallets. Not permitted for sacks on pallets. May contain only Carrier 
Route rate packages

[[Page 19743]]

for the same 5-digit scheme under L001. Scheme sort must be done for 
all 5-digit scheme destinations. For all 5-digit destinations that are 
not part of a scheme, prepare 5-digit carrier routes pallets under 
3.3c.
    (1) Line 1: use L001, Column B.
    (2) Line 2: ``PSVC FLTS,'' followed by ``CARRIER ROUTES'' or ``CR-

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 PAVE-certified 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 pallet level is the minimum volume that will be 
reallocated, where possible.

[Renumber current 1.2 through 1.6 as 1.3 through 1.7, respectively. Add 
new 1.2 to read as follows:]

1.2  Additional Standards for Sacked Flats Mailing Jobs Containing 
More Than One Mailing

    The following standards apply:
    a. If the mailing job contains a carrier route mailing, an 
automation rate mailing, and a Presorted rate mailing, then it must be 
prepared under one of the following options: (1) The carrier route 
mailing must be prepared under E630 and M620 and the automation rate 
and Presorted rate mailings must be prepared under M910; or (2) all 
three mailings in the mailing job must be prepared under M920.
    b. If the mailing job contains an automation rate mailing and a 
Presorted rate mailing, then it must be prepared under the co-sacking 
standards in M910.
    c. If the mailing job contains a carrier route mailing and a 
Presorted rate mailing, then it must be separately sacked under M610 
and M620 or prepared using the merged sacking option under M920.
    d. If the mailing job contains a carrier route mailing and an 
automation rate mailing, then it must be separately sacked under M620 
and M820 or prepared using the merged sacking option under M920.

[Delete renumbered 1.6 (former 1.5), Co-Sacking with Automation Rate 
Mail, and renumber 1.7 as 1.6.]

[Amend 1.6 to read as follows:]

1.6  Merged Containerization of Flat-Size Carrier Route, Automation 
Rate, and Presorted Rate Mail

    Under the optional preparation method in M920, 5-digit packages of 
Presorted flats must be co-sacked with packages of carrier route flats 
prepared under M620 and with 5-digit packages of automation flats 
prepared under M820 in merged 5-digit scheme sacks and merged 5-digit 
sacks. Under the optional preparation methods in M920, M930, or M940, 
5-digit packages of Presorted flats must be copalletized with packages 
of carrier route rate flats prepared under M620 and with 5-digit 
packages of automation rate flats prepared under M820 on merged 5-digit 
scheme pallets and merged 5-digit pallets. See 1.2a for information on 
when preparation under M920 may be required.

route rate flats must be co-sacked with 5-digit packages of Presorted 
rate flats prepared under M610 and with 5-digit packages of automation 
rate flats prepared under M820 in merged 5-digit scheme sacks and 
merged 5-digit sacks. Under the optional preparation methods in M920, 
M930, or M940, packages of carrier route rate flats must be 
copalletized with 5-digit packages of Presorted flats prepared under 
M610 and with 5-digit packages of automation rate flats prepared under 
M820 on merged 5-digit scheme pallets and merged 5-digit pallets.

[[Page 19744]]


    Note: The current DMM has the preparation standards for flats 
and irregulars combined into one section. Because the L001 scheme 
sort would 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 here 
because they have been renumbered and reorganized; however, there 
are no proposed changes to the mail preparation for irregular 
parcels.

[Amend 4.0 to add the required L001 scheme sort for flats to read as 
follows:]
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 single-piece 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 accompanying postage statement whether 
they applied the 125-piece (``PCS'') or 15-pound (``WT'') threshold or 
the method in 4.1b (``BOTH'').

4.2  Sack Preparation

    Sack size, preparation sequence, and labeling:
    a. Carrier route: required (minimum of 125 pieces/15 pounds, 
smaller volume not permitted).

5.0  SACK PREPARATION--IRREGULAR PARCELS

5.1  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 single-piece 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 accompanying postage statement whether 
they applied the 125-piece (``PCS'') or 15-pound (``WT'') threshold or 
the method in 4.1b (``BOTH'').
