MEMORANDUM

DATE:	February 2, 2015

SUBJECT:	Baseline and NSPS Emissions from Small and Large Forced-Air Furnaces

FROM:	Jill Mozier, EC/R Incorporated

TO:		Docket ID Number EPA-HQ-OAR-2009-0734

1.0	PURPOSE

This memorandum separates estimated emissions from small and large forced-air furnaces at baseline and assuming implementation of the final NSPS for Residential Wood Heaters.

We estimate, based on industry discussions with EPA, that 25% of current forced-air furnace sales are of small forced-air furnaces (those with less than 65,000 BTU/hr heat output) and 75% of current sales are of large forced-air furnaces (those with 65,000 BTU/hr heat output or larger). These percentages were used to separate estimated emissions from the forced-air furnace appliance category as a whole into emissions from small and large forced-air furnaces.

The emissions memorandum and the supporting cost effectiveness spreadsheets use the same percentages in the spreadsheet formulas to estimate NSPS emissions in 2016 (when small forced-air furnaces  -  an estimated 25% of forced-air furnace shipments  -  must meet the Step 1 limit) and in 2017 (when large forced-air furnaces  -  an estimated 75% of shipments  -  must also meet the Step 1 limit). Separate rows for small and large forced-air furnaces are presented in the following tables and in the Regulatory Impact Analysis (RIA).

The following tables are numbered according to how they appear in the RIA, which is available in the docket for this rulemaking.

ENVIRONMENTAL PROTECTION AGENCY

[EPA-HQ-OPP-2023-0463; FRL-11396-01-OCSPP]

Metamitron; Receipt of Application for Emergency Exemption,
Solicitation of Public Comment

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: EPA has received specific exemption requests from the Colorado
and Nebraska Departments of Agriculture to use the pesticide metamitron
(CAS No. 41394-05-2) to treat up to 69,596 acres of sugar beets to
control the invasive weed, Palmer amaranth. The applicants propose the
use of a new chemical which has not been registered by EPA. EPA is
soliciting public comment before making the decision whether or not to
grant the exemptions, in accordance with the regulation at 40 Code of
Federal Regulations (CFR) part 166.24(a)(1).

DATES: Comments must be received on or before October 13, 2023.

ADDRESSES: Submit your comments, identified by docket identification
(ID) number EPA-HQ-OPP-2023-0463, through the Federal eRulemaking
Portal at https://www.regulations.gov. Follow the online instructions
for submitting comments. Do not submit electronically any information
you consider to be Confidential Business Information (CBI) or other
information whose disclosure is restricted by statute. Additional
instructions on commenting and visiting the docket, along with more
information about dockets generally, is available at https://www.epa.gov/dockets.

FOR FURTHER INFORMATION CONTACT: Charles Smith, Director, Registration
Division (7505T), Office of Pesticide Programs, Environmental
Protection Agency, 1200 Pennsylvania Ave. NW, Washington, DC 20460-
0001; main telephone number:<PHONE_NUMBER>; email address:
[email protected].

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    You may be potentially affected by this action if you are an
agricultural producer, food manufacturer, or pesticide manufacturer.
The following list of North American Industrial Classification System
(NAICS) codes is not intended to be exhaustive, but rather provides a
guide to help readers determine whether this document applies to them.
Potentially affected entities may include:
     Crop production (NAICS code 111).
     Animal production (NAICS code 112).
     Food manufacturing (NAICS code 311).
     Pesticide manufacturing (NAICS code 32532).

B. What should I consider as I prepare my comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through
https://www.regulations.gov or email. Clearly mark the part or all of
the information that you claim to be CBI. For CBI information in a disk
or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM
as CBI and then identify electronically within the disk or CD-ROM the
specific information that is claimed as CBI. In addition to one
complete version of the comment that includes information claimed as
CBI, a copy of the comment that does not contain the information
claimed as CBI must be submitted for inclusion in the public docket.
Information so marked will not be disclosed except in accordance with
procedures set forth in 40 CFR part 2.
    2. Tips for preparing your comments. When preparing and submitting
your comments, see the commenting tips at https://www.epa.gov/dockets/commenting-epa-dockets.
    3. Environmental justice. EPA seeks to achieve environmental
justice, the fair treatment and meaningful involvement of any group,
including minority and/or low-income populations, in the development,
implementation, and enforcement of environmental laws, regulations, and
policies. To help address potential environmental justice issues, the
Agency seeks information on any groups or segments of the population
who, as a result of their location, cultural practices, or other
factors, may have atypical or disproportionately high and adverse human
health impacts or environmental effects from exposure to the pesticide
discussed in this document, compared to the general population.

II. What action is the Agency taking?

    Under section 18 of the Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA) (7 U.S.C. 136p), at the discretion of the EPA
Administrator, a Federal or State agency may be exempted from any
provision of FIFRA if the EPA Administrator determines that emergency
conditions exist which require the exemption. The Colorado and Nebraska
Departments of Agriculture have requested the EPA Administrator to
issue specific exemptions for the use of metamitron on sugar beets to
control Palmer amaranth. Information in accordance with 40 CFR part 166
was submitted as part of the requests.
    As part of this request, the applicants assert that emergency
conditions exist due to insufficient means to control Palmer amaranth
in sugar beets, and the use of metamitron will help avert significant
economic losses.
    The Applicants propose to apply a total of 64 fluid ounces per acre
of the unregistered product, Goltix 700 SC (containing 58.3%
metamitron, equivalent to 5.84 lbs. of metamitron per gallon of
product) on up to 22,468 acres of sugar beets in Colorado, and 47,128
acres in Nebraska (total of 69,596 acres) from April 1 to May 31, 2024,
using a potential product maximum of 11,234 gallons in Colorado and
23,564 gallons in Nebraska (total of 34,798 gallons of Goltix 700 SC,
equivalent to 203,221 lbs. of metamitron).

    This notice does not constitute a decision by EPA on the
applications themselves. The regulations governing FIFRA section 18 at
40 CFR part 166.24(a)(1) require publication of a notice of receipt of
an application for a specific exemption proposing use of a new chemical
(i.e., an active ingredient) which has not been registered by EPA. The
notice provides an opportunity for public comment on the applications.
    The Agency will review and consider all comments received during
the comment period in determining whether to issue the specific
exemptions requested by the Colorado and Nebraska Departments of
Agriculture.
    Authority: 7 U.S.C. 136 et seq.
