Emission Unit: {Site Specific List of Emission Unit(s)}

POLLUTION CONTROL EQUIPMENT

{Enter site specific control equipment used by each emission unit}

I. EMISSION LIMIT(S)

For pollutants in this table, choose the emission limits that the facility is to comply with, either output based (lb/GWh) or heat input based (lb/MMBtu or lb/TBtu). If the facility is using emission averaging to comply with MATS emission limits, do not mix emission limit bases within the EGU pollutant specific emissions averaging group. If the permittee is using emission averaging to comply, see attached appendix with Special Conditions to be added to the various sections of this table. Make sure that the Special Conditions numbering in the Monitoring/Testing Method matches the appropriate condition.

Limit additional language.

If the table has multiple units and not using emission averaging – Add the phrase “per boiler” or “per emission unit” or other similar language that clarifies that each emission limit applies to each unit after the limit the source has stated that they will be complying with

Time Period/Operating Scenario Language (except for SO2 and Hg 90-day):

Using CEMS to comply with limit – 30-boiler operating day rolling arithmetic average updated at the end of each new boiler operating day.

Using stack testing to comply with limit – Quarterly Stack Test (If it is a low emitting EGU {LEE} for a particular pollutant use the following: Annual Stack Test + [Hg only] or Triennial Stack Test + [any pollutant except Hg] Keep the superscript “+” with the LEE test per footnote at bottom of emission limits table)

Using a PM CPMS to comply with limit - 30-boiler operating day rolling arithmetic average of all of the quality assured hourly average PM CPMS output data updated at the end of each new boiler operating day

Using emission averaging to comply with limit - 30-group boiler operating day rolling weighted average emission rate, updated at the end of each new boiler operating day

The permittee must comply with the applicable emission limits at all times except for startup and shutdown periods unless the permittee chooses to use just one set of sorbent traps to demonstrate compliance with the applicable Hg emission limit, then the permittee must comply with the applicable Hg emission limit at all times. The permittee must collect monitoring data during startup periods, as specified in 40 CFR 63.10020(a) and (b). The permittee must keep records during startup periods, as provided in 40 CFR 63.10032 and 40 CFR 63.10021(h). Any fraction of an hour in which startup occurs constitutes a full hour of startup. (40 CFR Part 63, Subpart UUUUU, Table 3.3)

OR

If the permittee chooses to comply using paragraph (2) of the definition of ‘‘startup’’ in 40 CFR 63.10042

During startup, as defined by paragraph (2) of the definition of ‘‘startup’’ in 40 CFR 63.10042, the permittee must operate all Continuous Monitoring Systems (CMS), collect appropriate data, and calculate the pollutant emission rate for each hour of startup. Startup begins with either the firing of any fuel in an EGU for the purpose of producing electricity or useful thermal energy (such as heat or steam) for industrial, commercial, heating, or cooling purposes (other than the first-ever firing of fuel in a boiler following construction of the boiler) or for any other purpose after a shutdown event. Startup ends 4 hours after the EGU generates electricity that is sold or used for any other purpose (including on site use), or 4 hours after the EGU makes useful thermal energy (such as heat or steam) for industrial, commercial, heating, or cooling purposes, whichever is earlier. If the permittee chooses to use just one set of sorbent traps to demonstrate compliance with Hg emission limits, the permittee must comply with all applicable Hg emission limits at all times; otherwise, the permittee must comply with all applicable emission limits at all times except for startup or shutdown periods. The permittee must collect monitoring data during startup periods, as specified in 40 CFR 63.10020(a) and (e). The permittee must keep records during startup periods, as provided in 40 CFR 63.10032 and 40 CFR 63.10021(h). Any fraction of an hour in which startup occurs constitutes a full hour of startup. (40 CFR Part 63, Subpart UUUUU, Table 3.3)

ALWAYS INCLUDE

The permittee must operate all CMS during shutdown. The permittee must also collect appropriate data, and the permittee must calculate the pollutant emission rate for each hour of shutdown for those pollutants for which a CMS is used. The permittee must collect monitoring data during shutdown periods, as specified in 40 CFR 63.10020(a). The permittee must keep records during shutdown periods, as provided in 40 CFR 63.10032 and 40 CFR 63.10021(h). Any fraction of an hour in which shutdown occurs constitutes a full hour of shutdown. (40 CFR Part 63, Subpart UUUUU, Table 3.4)

If using a CMS to demonstrate continuous compliance, whether through quarterly testing and parametric monitoring or by CEMS or CPMS, with an emission limit or operating limit, the permittee must develop a site-specific monitoring plan and submit this site-specific monitoring plan, if requested, at least 60 days before the initial performance evaluation (where applicable) of the CMS. This requirement also applies to the permittee if the permittee petitions the Administrator for alternative monitoring parameters under 40 CFR 63.8(f). This requirement to develop and submit a site-specific monitoring plan does not apply to affected sources with existing monitoring plans that apply to CEMS and CPMS prepared under Appendix B of 40 CFR Part 60 or 40 CFR Part 75, and that meet the requirements of 40 CFR 63.10010. Using the process described in 40 CFR 63.8(f)(4), the permittee may request approval of monitoring system quality assurance and quality control procedures alternative to those specified in this paragraph of this section and, if approved, include those in the site-specific monitoring plan. The monitoring plan must address the following provisions:

(40 CFR 63.10000(d), 40 CFR 63.10010)

On-going recordkeeping and reporting procedures, in accordance with the general requirements of 40 CFR 63.10(c), (e)(1), and (e)(2)(i), or as specifically required under 40 CFR Part 63, Subpart UUUUU.

Alternatively, the requirements are considered to be met for a particular CMS or sorbent trap monitoring system if:

The CMS or sorbent trap monitoring system is installed, certified, maintained, operated, and quality-assured either according to 40 CFR Part 75, or Appendix A or B of 40 CFR Part 63, Subpart UUUUU; and

The recordkeeping and reporting requirements of 40 CFR Part 75, or Appendix A or B of 40 CFR Part 63, Subpart UUUUU, which pertain to the CMS, are met.

OPTIONAL - If they use a PM CEMS or participate in an averaging plan for one or more pollutants. If not all emission units in FGMATS have a PM CEMS, only include units that have this setup.

If the permittee elects to use a PM CEMS or participate in an averaging plan for PM, total non-Hg HAP metals, or individual metals, the permittee shall keep, in a satisfactory manner, hourly (if applicable) and 30-day rolling average PM, total non-Hg HAP metals, or individual metals (as applicable) emission rate records for each emission unit OR (30-day rolling weighted average PM, total non-Hg HAP metals, or individual metals (as applicable) emission rate records for the combination of units participating in an averaging plan) excluding periods of startup and shutdown. (40 CFR 63.10010, 40 CFR 63.10021, 40 CFR Part 63, Subpart UUUUU, Table 7)

OPTIONAL - If they use an Hg CEMS or sorbent trap monitoring system or participate in an averaging plan for Hg. If not all emission units in FGMATS have an Hg CEMS or sorbent trap monitoring system, only include units that have this setup.

The permittee must operate the monitoring system and collect data at all required intervals at all times that the affected EGU is operating, except for required monitoring system quality assurance or quality control activities, including, as applicable, calibration checks and required zero and span adjustments, and any scheduled maintenance as defined in the site-specific monitoring plan. The permittee is required to affect monitoring system repairs in response to monitoring system malfunctions and to return the monitoring system to operation as expeditiously as practicable. (40 CFR 63.10020(b))

The permittee may not use data recorded during startup or shutdown in calculations used to report emissions, except as otherwise provided in 40 CFR 63.10000(c)(1)(vi)(B) and 40 CFR 63.10005(a)(2)(iii). In addition, data recorded during monitoring system malfunctions or monitoring system out-of-control periods, repairs associated with monitoring system malfunctions or monitoring system out-of-control periods or required monitoring system quality assurance or control activities may not be used in calculations used to report emissions or operating levels. The permittee must use all of the quality-assured data collected during all other periods in assessing the operation of the control device and associated control system. (40 CFR 63.10020(c))

Failure to collect required quality-assured data during monitoring system malfunctions, monitoring system out-of-control periods, or repairs associated with monitoring system malfunctions or monitoring system out-of-control periods is a deviation from the monitoring requirements. Periods of monitoring system malfunctions or monitoring system out-of-control periods, repairs associated with monitoring system malfunctions or monitoring system out-of-control periods, and required monitoring system quality assurance or quality control activities excluding zero and span checks must be reported as time the monitor was inoperative (downtime) under 63.10(c).

Optional - Emissions Averaging per 40 CFR Part 63, Subpart UUUUU Conditions

INCLUDE IN SECTION I BELOW THE EMISSION LIMIT TABLE:

The permittee may use emissions averaging as described in paragraph 40 CFR 63.10009(a)(2) as an alternative to meeting the requirements of 40 CFR 63.9991 for filterable PM, SO2, HF, HCl, non-Hg HAP metals, or Hg on an EGU-specific basis if: (40 CFR 63.10009(a)(1)(i) and (ii))

The permittee has more than one existing EGU in the same subcategory located at one or more contiguous properties, belonging to a single major industrial grouping, which are under common control of the same person (or persons under common control); and

The permittee uses CEMS (or sorbent trap monitoring systems for determining Hg emissions) or quarterly emissions testing for demonstrating compliance.

INCLUDE IN SECTION V:

For all other groups of units subject to paragraph (k) of 40 CFR 63.10009, the permittee may elect to conduct manual performance tests according to procedures specified in 40 CFR 63.10007 in the common stack. If emissions from affected units included in the emissions averaging and from other units not included in the emissions averaging (e.g., in a different subcategory) or other non-affected units all vent to the common stack, the permittee must shut down the units not included in the emissions averaging group and the non-affected units or vent their emissions to a different stack during the performance test. Alternatively, the permittee may conduct a performance test of the combined emissions in the common stack with all units operating and show that the combined emissions meet the most stringent emissions limit. The permittee may also use a CEMS or sorbent trap monitoring to apply this latter alternative to demonstrate that the combined emissions comply with the most stringent emissions limit on a continuous basis. (40 CFR 63.10009(m))

INCLUDE IN SECTION VI:

The permittee shall for each 30- (or 90-) day rolling average period demonstrate compliance with the average weighted emissions limits of the emission units participating in the emissions averaging option as determined in 40 CFR 63.10009(f) and (g). (40 CFR 63.10022(a)(1))

The permittee shall for each emission unit participating in the emissions averaging option that is equipped with PM CPMS, maintain the average parameter value at or below the operating limit established during the most recent performance test. (40 CFR 63.10022(a)(2))

The permittee shall for each emission unit participating in the emissions averaging option venting to a common stack configuration containing affected units from other subcategories, maintain the appropriate operating limit for each unit as specified in Table 4 of 40 CFR Part 63, Subpart UUUUU that applies. (40 CFR 63.10022(a)(3))

The permittee may demonstrate compliance by emissions averaging among the existing EGUs in the same subcategory, if the averaged Hg emissions for EGUs in the ‘‘unit designed for coal ≥8,300 Btu/lb’’ subcategory are equal to or less than 1.2 lb/TBtu or 1.3E–2 lb/GWh on a 30-boiler operating day basis or if the averaged emissions of individual, other pollutants from other subcategories of such EGUs are equal to or less than the applicable emissions limit(s) in Table 2 of 40 CFR Part 63, Subpart UUUUU, according to the procedures in this section. Note that except for Hg emissions from EGUs in the ‘‘unit designed for coal ≥8,300 Btu/lb’’ subcategory, the averaging time for emissions averaging for pollutants is 30 days (rolling daily) using data from CEMS or a combination of data from CEMS and manual performance (LEE) testing. The averaging time for emissions averaging for the alternate Hg limit (equal to or less than 1.0 lb/TBtu or 1.1E–2 lb/GWh) from EGUs in the ‘‘unit designed for coal >8,300 Btu/lb’’ subcategory is 90 days (rolling daily) using data from CEMS, sorbent trap monitoring, or a combination of monitoring data and data from manual performance (LEE) testing. For the purposes of this paragraph, 30- (or 90-) day group boiler operating days is defined as a period during which at least one unit in the emissions averaging group has operated 30 (or 90) days. The permittee must calculate the weighted average emissions rate for the group in accordance with the procedures in this paragraph using the data from all units in the group including any that operate fewer than 30 (or 90) days during the preceding 30- (or 90-) group boiler days. (40 CFR 63.10009(a)(2))

The permittee may choose to have the EGU emissions averaging group meet either the heat input basis (MMBtu or TBtu, as appropriate for the pollutant) or gross output basis (MWh or GWh, as appropriate for the pollutant), but may not mix bases within the EGU emissions averaging group. The permittee may use emissions averaging for affected units in different subcategories if the units vent to the atmosphere through a common stack (see 40 CFR 63.10009(m)). (40 CFR 63.10009(a)(2)(i)-(iii))

The permittee must use the applicable equations in 40 CFR 63.10009(b) when performing calculations for the EGU emissions averaging group. (40 CFR 63.10009(b))

For a group of two or more existing EGUs in the same subcategory that each vent to a separate stack, the permittee may average filterable PM, SO2, HF, HCl, non-Hg HAP metals, or Hg emissions to demonstrate compliance with the limits in Table 2 of 40 CFR Part 63, Subpart UUUUU if the requirements in 40 CFR 63.10009 (d) through (j) of are satisfied. (40 CFR 63.10009(c))

The weighted-average emissions rate from the existing EGUs participating in the emissions averaging option must be in compliance with the limits in Table 2 of 40 CFR Part 63, Subpart UUUUU at all times following the date that the permittee begins emissions averaging. (40 CFR 63.10009(e))

The permittee must demonstrate the ability for the EGUs included in the emissions averaging group to demonstrate initial compliance according to paragraph (f)(1) or (2) of 40 CFR 63.10009 using the maximum rated heat input or gross output over a 30- (or 90-) boiler operating period of each EGU and the results of the initial performance tests. For this demonstration and prior to submitting the emissions averaging plan, if requested, the permittee must conduct required emissions monitoring for 30 (or 90) days of boiler operation and any required manual performance testing to calculate maximum weighted average emissions rate in accordance with 40 CFR 63.10009. If, before the start of the initial compliance demonstration, the Administrator becomes aware that the permittee intends to use emissions averaging for that demonstration, or if the permittee’s initial Notification of Compliance Status (NOCS) indicates the intent to implement emissions averaging at a future date, the Administrator may require the permittee to submit the proposed emissions averaging plan and supporting data for approval. If the Administrator requires approval of the plan, the permittee may not begin using emissions averaging until the Administrator approves the plan.

(40 CFR 63.10009(f)(1) and (2))

The permittee must use Equation 1a in paragraph (b) of 40 CFR 63.10009 to demonstrate that the maximum weighted average emission rates of filterable PM, HF, SO2, HCl, non-Hg HAP metals, or Hg emissions from the existing units participating in the emissions averaging option do not exceed the emission limits in Table 2 of 40 CFR Part 63, Subpart UUUUU.

If the permittee is not capable of monitoring heat input or gross output, and the EGU generates steam for purposes other than generating electricity, the permittee may use Equation 1b of 40 CFR 63.10009 as an alternative to using Equation 1a of 40 CFR 63.10009 to demonstrate that the maximum weighted average emission rates of filterable PM, HF, SO2, HCl, non-Hg HAP metals, or Hg emissions from the existing units participating in the emissions averaging group do not exceed the emission limits in Table 2 of 40 CFR Part 63, Subpart UUUUU.

The permittee must determine the weighted average emissions rate in units of the applicable emissions limit(s) on a 30-group boiler operating day rolling average basis (or, if applicable, on a 90-group boiler operating day rolling average basis for Hg) basis according to paragraphs (g)(1) through (2) of 40 CFR 63.10009. The first averaging period begins on the 30th (or, if applicable, 90th for the alternate Hg emission limit) group boiler operating day after the date the permittee begins emissions averaging. (40 CFR 63.10009(g)(1) and (2))

The permittee must use Equation 2a or 3a of paragraph (b) of 40 CFR 63.10009 to calculate the weighted average emissions rate using the actual heat input or gross output for each existing unit participating in the emissions averaging option.

If the permittee is not capable of monitoring heat input or gross output, the permittee may use Equation 2b or 3b of paragraph (b) of 40 CFR 63.10009 as an alternative to using Equation 2a of paragraph (b) of 40 CFR 63.10009 to calculate the average weighted emission rate using the actual steam generation from the units participating in the emissions averaging option.

If an EGU in the emissions averaging group uses CEMS (or a sorbent trap monitor for Hg emissions) to demonstrate compliance, the permittee must use that data to determine the 30- (or 90-) group boiler operating day rolling average emissions rate. (40 CFR 63.10009(h))

If the permittee uses manual emissions testing to demonstrate compliance for one or more EGUs in the emissions averaging group, the permittee must use the results from the most recent performance test to determine the 30- (or 90-) day rolling average. The permittee may use CEMS or sorbent trap data in combination with data from the most recent manual performance test in calculating the 30- (or 90-) group boiler operating day rolling average emissions rate. (40 CFR 63.10009(i))

The Administrator shall use following criteria in reviewing and approving or disapproving the plan:

(40 CFR 63.10009(j)(2)(i))

Whether the content of the plan includes all the information specified in 40 CFR 63.10009(j)(1) of; and

For each existing EGU in the averaging group: (40 CFR 63.10009(d)(1) and (2))

The emissions rate achieved during the initial performance test for the HAP being averaged must not exceed the emissions level that was being achieved 180 days after April 16, 2016, or the date on which emissions testing done to support the emissions averaging plan is complete (if the Administrator does not require submission and approval of the emissions averaging plan), or the date that the permittee begins emissions averaging, whichever is earlier;

The control technology employed during the initial performance test must not be less than the design efficiency of the emissions control technology employed 180 days after April 16, 2016 or the date that the permittee begins emissions averaging, whichever is earlier.

For a group of two or more existing affected units, each of which vents through a single common stack, the permittee may average emissions to demonstrate compliance with the limits in Table 2 of 40 CFR Part 63, Subpart UUUUU if the requirements in 40 CFR 63.10009(l) or (m) are satisfied. (40 CFR 63.10009(k))

For a group of two or more existing units in the same subcategory and which vent through a common emissions control system to a common stack that does not receive emissions from units in other subcategories or categories, the permittee may treat such averaging group as a single existing unit for purposes of this subpart and comply with the requirements of this subpart as if the group were a single unit. (40 CFR 63.10009(l))

The common stack of a group of two or more existing EGUs in the same subcategory subject to paragraph (k) of 40 CFR 63.10009 may be treated as a single stack for purposes of paragraph (c) of 40 CFR 63.10009 and included in an emission averaging group subject to paragraph (c) of 40 CFR 63.10009.
