* * * * *
    (b) Excess emissions/summary report. The owner or operator of a
major or area source must submit semiannual reports according to the
requirements in Sec.  63.10(e)(3). Except, the owner or operator must
submit the semiannual reports within 60 days after the end of each 6-
month period instead of within 30 days after the calendar half as
specified in Sec.  63.10(e)(3)(v). When no deviations of parameters
have occurred, the owner or operator must submit a report stating that
no excess emissions occurred during the reporting period.
* * * * *
    (2) * * *
    (vii) For each affected source choosing to demonstrate compliance
during periods of startup and shutdown in accordance with Sec.
63.1513(f)(1): ``During each startup and shutdown, no flux and no feed/
charge were added to the emission unit, and electricity, propane or
natural gas were used as the sole source of heat or the emission unit
was not heated.''
* * * * *
    (3) * * *
    (i) Within 60 days after the date of completing each performance
test (as defined in Sec.  63.2) required by this subpart, you must
submit the results of the performance tests, including any associated
fuel analyses, following the procedure specified in either paragraph
(b)(3)(i)(A) or (B) of this section.
    (A) For data collected using test methods supported by the EPA's
Electronic Reporting Tool (ERT) as listed on the EPA's ERT Web site
(http://www.epa.gov/ttn/chief/ert/index.html), you must submit the
results of the performance test to the EPA via the Compliance and
Emissions Data Reporting Interface (CEDRI). CEDRI can be accessed
through the EPA's Central Data Exchange (CDX) (http://cdx.epa.gov/epa_home.asp). Performance test data must be submitted in a file format
generated through the use of the EPA's ERT. Alternatively, you may
submit performance test data in an electronic file format consistent
with the extensible markup language (XML) schema listed on the EPA's
ERT Web site once the XML schema is available. If you claim that some
of the performance test information being submitted is confidential
business information (CBI), you must submit a complete file generated
through the use of the EPA's ERT or an alternate electronic file
consistent with the XML schema listed on the EPA's ERT Web site,
including information claimed to be CBI, on a compact disc, flash
drive, or other commonly used electronic storage media to the EPA. The
electronic media must be clearly marked as CBI and mailed to U.S. EPA/
OAPQS/CORE CBI Office, Attention: Group Leader, Measurement Policy
Group, MD C404-02, 4930 Old Page Rd., Durham, NC 27703. The same ERT or
alternate file with the CBI omitted must be submitted to the EPA via
the EPA's CDX as described earlier in this paragraph.
    (B) For data collected using test methods that are not supported by
the EPA's ERT as listed on the EPA's ERT Web site, you must submit the
results of the performance test to the Administrator at the appropriate
address listed in Sec.  63.13.
* * * * *
    (c) Annual compliance certifications. For the purpose of annual
certifications of compliance required by 40 CFR part 70 or 71, the
owner or operator of a major source subject to this subpart must
certify continuing compliance based upon, but not limited to, the
following conditions:
* * * * *
    (d) If there was a malfunction during the reporting period, the
owner or operator must submit a report that includes the emission unit
ID, monitor ID, pollutant or parameter monitored, beginning date and
time of the event, end date and time of the event, cause of the
deviation or exceedance and corrective action taken for each
malfunction which occurred during the reporting period and which caused
or may have caused any applicable emission limitation to be exceeded.
The report must include a list of the affected source or equipment, an
estimate of the quantity of each regulated pollutant emitted over any
emission limit, and a description of the method used to estimate the
emissions, including, but not limited to, product-loss calculations,
mass balance calculations, measurements when available, or engineering
judgment based on known process parameters. The report must also
include a description of actions taken by an owner or operator during a
malfunction of an affected source to minimize emissions in accordance
with Sec. Sec.  63.1506(a)(5) and 63.1520(a)(8).
    (e) All reports required by this subpart not subject to the
requirements in paragraph (b) of this section must be sent to the
Administrator at the appropriate address listed in Sec.  63.13. If
acceptable to both the Administrator and the owner or operator of a
source, these reports may be submitted on electronic media. The
Administrator retains the right to require submittal of reports subject
to paragraph (b) of this section in paper format.

    (1) * * *
    (iii) If an aluminum scrap shredder is subject to visible emission
observation requirements, records of all Method 9 observations,
including records of any visible emissions during a 30-minute daily
test or records of all ASTM D7520-13 observations (incorporated by
reference, see Sec.  63.14), including data sheets and all raw

monthly inspections of feeder setting, including records of any
deviation of the feeder setting from the setting used in the
performance test, with a brief

explanation of the cause of the deviation and the corrective action
taken. If a lime feeder has been repaired or replaced, this action must
be documented along with records of the new feeder calibration and the
feed mechanism set points necessary to maintain the lb/hr feed rate
operating limit. These records must be maintained on site and available
upon request.
* * * * *

parameter monitored, beginning date and time of the event, end date and
time of the event, cause of the deviation or exceedance and corrective
action taken.

minimize emissions in accordance with Sec. Sec.  63.1506(a)(5) and
63.1520(a)(8), including corrective actions to restore malfunctioning
process and air pollution control and monitoring equipment to its
normal or usual manner of operation.
    (19) For each period of startup or shutdown for which the owner or
operator chooses to demonstrate compliance for an affected source, the
owner or operator must comply with (b)(19)(i) or (ii) of this section.
    (i) To demonstrate compliance based on a feed/charge rate of zero,
a flux rate of zero and the use of electricity, propane or natural gas
as the sole sources of heating or the lack of heating, the owner or
operator must submit a semiannual report in accordance with Sec.
63.1516(b)(2)(vii) or maintain the following records:
    (A) The date and time of each startup and shutdown;
    (B) The quantities of feed/charge and flux introduced during each
startup and shutdown; and
    (C) The types of fuel used to heat the unit, or that no fuel was
used, during startup and shutdown; or
    (ii) To demonstrate compliance based on performance tests, the
owner or operator must maintain the following records:
    (A) The date and time of each startup and shutdown;
    (B) The measured emissions in lb/hr or [mu]g/hr or ng/hr;
    (C) The measured feed/charge rate in tons/hr or Mg/hr from your
most recent performance test associated with a production rate greater

performance test data is available; and
    (D) An explanation to support that such conditions are considered
representative startup and shutdown operations.
    (20) For owners or operators that choose to change furnace
operating modes, the following records must be maintained:
    (i) The date and time of each change in furnace operating mode, and
    (ii)The nature of the change in operating mode (for example, group
1 controlled furnace processing other than clean charge to group 2).

Summary of Halogenated Solvent Emissions From Degreasers Identified in the 1999 NEI Database ( a)  Not Co Located facilities are those facilities that only report degreasing SCC codes in the database. If a facility reported a halogenated degreasing SCC code and a non halogenated SCC code it was classified as not co located, since all of the reported processes are degreasers.

( b)  Co located facilities are those facilities that reported non degreasing SCC codes or empty SCC code fields in addition to degreasing SCC codes.
