March 6, 2009 compliance | March 6, 2009 compliance Purpose The above listed certificates of operation for Tennessee Valley Authority (TVA) are due to expire on July 17, 2012. An annual inspection of the equipment that is covered by the certificates was made at Sequoyah Nuclear Plant on March 4, 2009. The: observations that were made during the inspection are summarized in this report. This report also includes discussions of the operation of the permitted equipment, the air pollutant emissions, and the applicable regulations. | ||

For each reactor unit, this pressurized water, which circulates in a closed loop, is used as a source of heat to produce steam inside of four parallel steam generators. | ||

The steam is condensed after it exits the four turbines, | The steam is condensed after it exits the four turbines, and the water, whether in the liquid or gaseous (steam) state, circulates in a closed loop for each unit.This water is circulated by two parallel feedwater pumps that are each driven by a turbine. These two turbines for each unit are powered by "extraction" steam that is diverted from the initial high-pressure turbine.Water from the adjacent Tennessee River is used to condense the steam. Reintroduction of this water into the river cannot result in the downstream temperature of the river being raised by more than 5.4°F during the months of April through October and 9.0°F during the months of November through March as averaged over a 24-hour period. The temperature of the water that is discharged into the river also cannot fluctuate by more than 3.6°F during any hour. Holding ponds are sometimes sufficient to cool the water to the desired temperature. | ||
However, it is often necessary to cool this water further in either of two cooling towers, which are designated as the Unit #1 cooling tower (Certificate | |||
-01C) and the Unit #2 cooling tower (Certificate | -01C) and the Unit #2 cooling tower (Certificate | ||
-03C). | -03C). In addition, reintroduction of the water into the river cannot result in the downstream river temperature exceeding an average of 86.9°F over a 24-hour period unless the water is being cooled in gne cooling tower per operating reactor unit. Water mist that is emitted from the two cooling towvers contains entrained particulate matter. These particulate emissions are uncontrolled and originate from dirt, silt, etc. in the river water.For each of the two reactor units, the initial high-pressure turbine and the two feedwater pump turbines are each supplied with lubricating oil by an oil recirculation system. In addition, the electricity generator of each unit is supplied with seal oil by an oil recirculation system. Each of these eight recirculation systems includes an oil reservoir that is equipped with an oil vapor extractor. | ||

Hydrogen is not considered to be an air pollutant. | ||

This operational limitation is more stringent than the Rule 2.7 limit of 20 days/yr (480 hrs/yr) for the operation of any generator that emits more than 1,500 ppm of NOx. Rule 2.7 also limits the operation of such generators to no more than 5 consecutive days.

March 4, 2009 and enforcement Full Compliance Evaluation Completed:
March 6, 2009 compliance Purpose The above listed certificates of operation for Tennessee Valley Authority (TVA) are due to expire on July 17, 2012. An annual inspection of the equipment that is covered by the certificates was made at Sequoyah Nuclear Plant on March 4, 2009. The: observations that were made during the inspection are summarized in this report. This report also includes discussions of the operation of the permitted equipment, the air pollutant emissions, and the applicable regulations.
Process Description TVA Sequoyah uses two nuclear reactors, which are referred to as Reactor Units #1 and#2, to heat pressurized water. For each reactor unit, this pressurized water, which circulates in a closed loop, is used as a source of heat to produce steam inside of four parallel steam generators.
The resulting steam from the four steam generators of each unit is sent to a common header and is then used in a high-pressure turbine followed by three low-pressure turbines in series to power a generator that produces electricity.
The steam is condensed after it exits the four turbines, and the water, whether in the liquid or gaseous (steam) state, circulates in a closed loop for each unit.This water is circulated by two parallel feedwater pumps that are each driven by a turbine. These two turbines for each unit are powered by "extraction" steam that is diverted from the initial high-pressure turbine.Water from the adjacent Tennessee River is used to condense the steam. Reintroduction of this water into the river cannot result in the downstream temperature of the river being raised by more than 5.4°F during the months of April through October and 9.0°F during the months of November through March as averaged over a 24-hour period. The temperature of the water that is discharged into the river also cannot fluctuate by more than 3.6°F during any hour. Holding ponds are sometimes sufficient to cool the water to the desired temperature.
However, it is often necessary to cool this water further in either of two cooling towers, which are designated as the Unit #1 cooling tower (Certificate
-01C) and the Unit #2 cooling tower (Certificate
-03C). In addition, reintroduction of the water into the river cannot result in the downstream river temperature exceeding an average of 86.9°F over a 24-hour period unless the water is being cooled in gne cooling tower per operating reactor unit. Water mist that is emitted from the two cooling towvers contains entrained particulate matter. These particulate emissions are uncontrolled and originate from dirt, silt, etc. in the river water.For each of the two reactor units, the initial high-pressure turbine and the two feedwater pump turbines are each supplied with lubricating oil by an oil recirculation system. In addition, the electricity generator of each unit is supplied with seal oil by an oil recirculation system. Each of these eight recirculation systems includes an oil reservoir that is equipped with an oil vapor extractor.
The extractors serve to vent oil vapor from the air space above the oil reservoirs.
Each of the eight oil vapor extractors also serves to remove water from the oil that results from inadvertent contact between the oil and steam. Hydrogen gas is used to cool the bearings of the two electricity generators, and the oil vapor extractor for the seal oil reservoir of each generator also serves to remove dissolved hydrogen from the oil. Hydrogen is not considered to be an air pollutant.
Particulate emissions of oil mist, which is a VOC, result from each of the eight oil vapor extractors.
The oil mist emissions from the extractor for the oil reservoir of the initial high-pressure turbine of each unit are controlled by a demister, and the oil mist emissions from the other six oil vapor extractors are uncontrolled.
Oil vapor extractors for coal-fired steam generating facilities are classified as insignificant activities in accordance with §8(a)(1)a.
However, because such extractors for nuclear-powered steam generating facilities are not specifically listed as insignificant activities, TVA has been informed that installation permits and initial certificates of operation will be issued for the Unit #1 and Unit #2 oil vapor extractors.

- If both nuclear reactor units are not in operation, either Auxiliary Boiler A or B (Certificate
-08C) could be used to preheat water for the steam generators in preparation for starting up one of the reactor units. The boiler would then be shut off when the reactor comes on line. In addition, either of these two identical boilers could be used as needed to heat the turbine building in order to keep water in pipes from freezing during the winter months if both reactor units are not in operation.
The auxiliary boilers are not normally used, however, because at least one of the two reactor units should be in operation at any time. The two boilers are fueled exclusively by low-sulfur diesel fuel (No. 2 fuel oil), and emissions that result from fuel combustion in them are uncontrolled.
They are vented to a single exhaust stack.Emergency Generators IA, 1B, 2A, and 2B (Certificate -llC) are available to provide electric power for safely shutting down the nuclear reactors in the unlikely event of a loss of off-site power to the plant. In addition, "Blackout" Generators 1 and 2 are available for a similar purpose. Only one emergency generator would be needed per operating reactor. Emergency Generators IA and 1B serve Reactor Unit #1, and Reactor Unit #2 is served by Emergency Generators 2A and 2B. Each of the four identical emergency generators and two identical blackout generators is powered by an internal-combustion engine that is fueled exclusively by low-sulfur diesel fuel, and emissions that result from fuel combustion in them are uncontrolled.
Each of the engines for the four emergency generators is equipped with two exhaust stacks.There has never been an unintended loss of power that required the use of any of the six generators, although they are periodically operated for test purposes.In the event of a loss of power to the plant, seven other generators are available to provide electric.power for specific needs. These seven generators, along with four water pumps, are each powered by a small internal-combustion engine that is fueled exclusively by low-sulfur diesel fuel. Most of them are periodically operated for test purposes, and emissions that result from fuel combustion in them are uncontrolled.
Diesel fuel is burned in the largest of these eleven engines at a maximum rate of 31.1 gal/hr (4.26 MMBtuihr), and each of them is not required to be permitted in accordance with §4-8(d)(3).
Two band saws (Certificate
-06C) are used to cut insulation to fit various components at the plant. These components include piping and pressure vessels. The two saws are primarily used to cut calcium silicate (CaSiO 3) insulation, but they can also be used to cut other types of insulation material, such as rubber. No material containing asbestos is ever cut by either of these saws. Insulation Saw A is used primarily.
Insulation Saw B is not currently used, but it is available for use as a backup unit. For Saw A, particulate emissions from a large suction hose that is mounted near the working section of the band saw blade are controlled by a prefilter followed by a HEPA (high-efficiency particulate air) filter. Particulate emissions from a hood that is over this saw are also controlled by a prefilter followed by a HEPA filter. These two HEPA filters are vented to a single exhaust hose. For Saw B, three prefilters in parallel followed by three HEPA filters in parallel are used to control particulate emissions from a large suction hose that is positioned near the working section of the band saw blade. In addition, for each of Saws A and B, a settling drum followed by a bag filter is used to control particulate emissions from each of two suction vents that are both located under the work table and adjacent to the band saw blade.Tennessee Valley Authority
-Sequoyah Nuclear Plant Page 3 A carpenter shop (Certificate
-09C) contains two radial-arm saws, a table saw, a band saw, and a planer. Particulate emissions of sawdust from all of these pieces of woodworking equipment are controlled by a baghouse.
This baghouse is also used to control particulate emissions from two floor vents that sawdust is swept into.Abrasive blasting (Certificate
-10C) of sheet metal is performed within a large enclosed room using a manual nozzle. Boiler slag, under the trade name of Black Beauty, is used as the abrasive.
Particulate emissions from this operation are controlled by a filter panel.Ten test welding booths are occasionally used for training purposes.
Stick, TIG (tungsten inert gas), and MIG (metal inert gas) welding is performed in these booths, and uncontrolled particulate emissions from these booths are vented to a single exhaust stack. In addition, a saw is used to cut small sections of steel pipe that have been welded in the booths in order to test the integrity of the welds. Particulate emissions of steel dust from this saw are controlled by a HEPA filter. Maintenance welding is an insignificant activity, and because the test welding booths and saw are used only in conjunction with training workers to perform maintenance welding, they are also classified as insignificant activities in accordance with §8(a)(1)a.
Evaluation 4150-30600701-OIC Unit #1 Cooling Tower 4150-30600701-03C Unit #2 Cooling Tower The Unit #1 and Unit #2 cooling towers were not in operation at the time of the inspection.
Reactor Units #1 and #2 were both on line. Both cooling towers appeared to be in good condition.
Each of the two cooling towers was used for 3,435 hours0.00503 days <br />0.121 hours <br />7.19246e-4 weeks <br />1.655175e-4 months <br /> during calendar year 2007. The estimated particulate emissions from each of these towers are given in Table I at the end of this section. The potential emissions are based on continuous operation.
Installation of the Unit #1 and #2 cooling towers was completed in 1980. The particulate emissions from each of the two cooling towers are limited by Rule 10.3 (Schedule
- 2) to 115.2 lbs/hr, based on a process weight of 139,690 tons/hr. This limitation is more stringent than the Rule 10.7 particulate emission limit of 0.25 gr/scf (85,760 lbs/hr) for each tower. However, a more stringent particulate emission limitation of 7.2 lbs/hr has been previously established for each tower because it has been determined that operation at the Rule 10.3 allowable emission rate would result in the creation of a particulate non-attainment area.4150-30700804-06C Insulation Saws A and B Insulation Saw A was in normal operation during the inspection.
Insulation Saw B is not currently in use. Saw A and its two prefilters, two HEPA filters, two settling drums, and two bag Tennessee Valley Authority

The two settling drums and two bag filters for use with Saw B were not in place, and they will be reinstalled before the saw is ever used again. No emissions Were visible.Saw A is used for an average of 4 hrs/day, 5 days/wk, and 6 wks/yr. Saw B was last operated no later than in 2003. Each HEPA filter has an estimated particulate control efficiency of 99.9%. Each settling drum and bag filter in series is estimated to be 94% efficient in controlling particulate emissions.
The estimated particulate emissions from each of the two saws are given in Table I.These emissions are conservatively based on control only by a settling drum followed by a bag filter. The potential emissions are based on continuous operation.
Insulation Saw A was installed in 1989. The particulate emissions from this saw are limited by Rule 10.3 (Schedule
- 2) to 0.49 lb/hr, based on a process weight of 80 lbs/hr. In addition, the particulate emissions from each of the exhaust points of this saw are limited by Rule 10.7 to 0.25 gr/scf. This limitation is equivalent to 0.39 lb/hr for each of the two bag filters.This limitation cannot be converted into units of lbs/hr for the set of HEPA filters because the exhaust flow rate through the filters is not available at this time.Insulation Saw B was installed in about 1988. However, as of 2005, Insulation Saw B went for two years without being operated, and it was no longer considered to be an existing source at that time, in accordance with §8(c)(1).
Potential particulate emissions from Saw B, before being controlled, are estimated to be 9.7 tons/yr. Therefore, the particulate emissions from this saw are subject to Rule 27.3. Control of these emissions by a settling drum followed by a bag filter has been determined to be reasonable and proper, in accordance with Rule 27.3.An appropriate reasonable and proper limitation for the particulate emissions from Saw B has been previously determined to be 0.20 lb/hr. This limitation is more stringent than both the Rule 10.3 (Schedule
- 2) particulate emission limit of 0.49 lb/hr, based on a process weight of 80 lbs/hr, and the Rule 10.7 particulate emission limit of 0.25 gr/scf, which is equivalent to 0.39 lb/hr for each of the two bag filters of this saw. The Rule 10.7 limit cannot be converted into units of lbs/hr for the set of HEPA filters of this saw because the exhaust flow rate through the filters is not available at this time.4150-10200501-08C Auxiliary Boilers A and B Auxiliary Boilers A and B are not currently in use. These two boilers appeared to be in good condition.
The required certifications of diesel fuel sulfur content and the required logs of daily hours of operation and monthly diesel fuel usage for each boiler were being maintained.
Each of the two boilers has a rated capacity of 54.5 MMBtu/hr.
They are normally not in use. Boiler A was last operated briefly (22 minutes) for test purposes on September 16, 2004, and Boiler B was last operated-on November 14, 2000. They are fueled exclusively by diesel fuel that has average and maximum sulfur contents of 0.05% and 0.06% by weight, respectively.
Tennessee Valley Authority
-Sequoyah Nuclear Plant Page 5 The estimated emissions of particulate (PM 2.5 , PMI 0 , and total), NOx, SOx, CO, VOCs, and methane that result from diesel fuel combustion in the two boilers combined are given in Table II at the end of this section. These emissions were calculated by using AP-42 (1998)emission.
factors. The potential emissions are based on simultaneous operation of the two boilers at their rated capacities while burning diesel fuel that has the maximum sulfur content. The potential emissions are also based on the sum of the total amount of time that Boiler A is in operation and the total amount of time that Boiler B is in operation being equal to 2,000 hrs/yr.47.0% and 69.7% of the particulate emissions that result from burning diesel fuel in the boilers are PM 2.5 and PM 1 0 , respectively.
The VOC emissions that result from diesel fuel combustion in the boilers consist of up to 28.4% formaldehyde (methanal, H 2 CO), which is a HAP. Both of these percentages were determined by using AP-42 (1998) emission factors.Auxiliary Boilers A and B were installed in 1976. However, as of November 15, 2002, the two boilers went for two years without being operated, and they were no longer considered to be existing sources at that time, in accordance with §8(c)(1).
These boilers are therefore subject to the provisions of "Standards of Performance for Small Industrial-Commercial-Institutional Steam Generating Units" [40 CFR Part 60, Subpart Dc (§60.40c-48c)], as adopted at Rule 15.§60.42c(d) of Subpart Dc stipulates that no fuel shall be burned in either boiler that has a sulfur content of greater than 0.5% by weight. Reporting and recordkeeping requirements are given in§60.48c of this subpart.Potential NOx emissions from each of Boilers A and B are estimated to be 7.956 lbs/hr.An appropriate NOx emission limitation for each of the two boilers has been previously determined to be 9.0 lbs/hr. An appriopriate limitation has also been previously determined to be that the sum of the total amount of time during which Boiler A is in operation and the total amount of time during which Boiler B is in operation shall not exceed 2,000 hrs/yr. These NOx emission and operational limitations result in an appropriate NOx emission limitation of 9.0 tons/yr for the two boilers combined.
TVA requested all of these limitations in order to qualify as a synthetic minor source. The potential emissions that are given in Table II are based upon the operational limitation.
Potential particulate emissions from each of Boilers A and B are estimated to be 1.313 lbs/hr and 5.7 tons/yr, based on continuous operation.
Therefore, the particulate emissions from these boilers are subject to Rule 27.3. An appropriate reasonable and proper limitation, in accordance with Rule 27.3, for the particulate emissions from each of Boilers A and B has been previously determined to be 0.030 lb/MMBtu, which is equivalent to 1.64 lbs/hr for each boiler while it is operating at its rated capacity.
No controls are necessary in order to achieve this limitation for either boiler. This limitation is equivalent to the particulate emission limit that, although not applicable to the two boilers, is stipulated by §60.43c(e)(1) of Subpart Dc. This limitation is more stringent than the Rule 8.2 (Schedule
- 2) particulate emission limit of 12.72 lbs/hr for each boiler. This limitation is also more stringent than the Rule 26.6 (RACT)particulate emission limit of 0.15864 lb/MMBtu, which, although it is not applicable to the two boilers, is equivalent to 8.65 lbs/hr for each boiler while it is operating at its rated capacity.Tennessee Valley Authority
-Sequoyah Nuclear Plant Page 6 An appropriate sulfur content limitation for the diesel fuel that is burned in Boilers A and B has been previously determined to be 0.06% by weight. TVA requested this limitation in order to qualify as a synthetic minor source. Combustion of diesel fuel with the maximum allowable sulfur content in either boiler at its rated capacity results in potential SOx emissions of 3.44 lbs/hr. This SOx emission rate is the effective SOx emission limitation for each boiler. This limitation is more stringent than the Rule 13.2 SO 2 emission limit of 4 lbs/MMBtu, which is equivalent to 218.0 lbs/hr for each of the two boilers while they are operating at their rated capacities.
The VOC emissions from Boilers A and B are subject to BACT (Rule 25.3). It has been determined that no controls are necessary in order to satisfy BACT for these emissions, and no quantitative BACT VOC emission limitations are necessary.
No limitations are applicable for the emissions of CO and methane from either of the two boilers.4150-30703099-09C Carpenter Shop None of the equipment of the carpenter shop was in operation at the time of the inspection.
The two radial-arm saws, table saw, band saw, planer, two floor vents, and baghouse appeared to be in good condition.
The carpenter shop is operated for approximately 4 hrs/day, 5 days/wk, and 6 wks/yr.The baghouse has an estimated particulate control efficiency of 99%. The estimated particulate emissions from this carpenter shop are given in Table I. The potential emissions are based on continuous operation.
The carpenter shop was installed in May 1995. The particulate emissions from this carpenter shop are limited by Rule 10.3 (Schedule
- 2) to 1.42 lbs/hr, based on a process weight of 450 lbs/hr. This limitation is more stringent than the Rule 10.7 particulate emission limit of 0.25 gr/scf (3.43 lbs/hr).4150-30900203-1 OC Abrasive Blasting Operation Abrasive blasting was not being performed at the time of the inspection.
The room that it is performed in and the filter panel appeared to be in good condition.
The abrasive blasting operation is used for approximately 3 hrs/day, 5 days/wk, and 8 wks/yr. Abrasive is blasted at a rate of approximately 500 lbs/hr. The filter panel has an estimated particulate control efficiency of 95%.The estimated particulate emissions from this operation are given in Table I. These emissions were calculated by using an AP-42 (1997) uncontrolled particulate emission factor of 0.027 pound per pound of sand multiplied by (0.010 pound per pound of abrasive)/(0.041 pound Tennessee Valley Authority
-Sequoyah Nuclear Plant Page. 7 per pound of sand), which is a ratio of SCAQMD uncontrolled particulate emission factors. The potential emissions are based on continuous operation.
The abrasive blasting operation began to be used in 1996, and potential particulate emissions from it, before being controlled, are estimated to be 14.4 tons/yr. Therefore, the particulate emissions from this operation are subject to Rule 27.3. Control of these emissions by a filter panel has been determined to be reasonable and proper, in accordance with Rule 27.3. An appropriate reasonable and proper limitation for the particulate emissions from this operation has been previously determined to be 0.30 lb/hr., This limitation is more stringent than both the Rule 10.3 (Schedule
- 2) particulate emission limit of 1.52 lbs/hr and the Rule 10.7 particulate emission limit of 0.25 gr/scf (55.71 lbs/hr).4150-20200102-11C Emergency Generators 1A, :IB, 2A, and 2B and Blackout Generators I and 2 Emergency Generators IA, IB, 2A, and 2B and Blackout Generators 1 and 2 were not in operation at the time of the inspection.
These six generators all appeared to be in good condition.
The required certifications of diesel fuel sulfur content and the required log of daily hours of operation for each of the generators were being maintained.
The four emergency generators each have a rated capacity of 38.4 MMBtu/hr, and they are each normally tested at a heat input rate of about 34.25 MMBtu/hr.
Each of the two blackout generators is normally tested at 50% of its rated capacity of 18.5 MMBtu/hr.
The six generators are fueled exclusively by diesel fuel that has average and maximum sulfur contents of 0.05% and 0.06% by weight, respectively.
The six generators are normally operated only during testing. During the twelve-month period from April 1, 2007, through March 31, 2008, annual testing times were 59.8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> for Generator IA, 63.9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> for Generator 1B, 56.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> for Generator 2A, 59.8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> for Generator 2B, 5.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> for Blackout Generator 1, and 5.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> for Blackout Generator 2.The estimated emissions of particulate (PM 2.5 , PM 1 0 , and total), NOx, SOx, CO, VOCs, and methane that result from diesel fuel combustion in the six generators combined are given in Table II. These emissions were calculated by using emission factors from AP-42 (1996) Table 3.4-2 for particulate; AP-42 (1996) Table 3.4-1 for NOx, CO, VOCs, and methane; and AP-42 (1998) Table 1.3-1 for SOx. The potential emissions are based on simultaneous operation of the six generators at their rated capacities for 204 hrs/yr while burning diesel fuel that has the maximum sulfur content. According to AP-42 (1996) emission factors, 79.8% and 82.2% of the particulate emissions that result from burning diesel fuel in the generators are PM 2.5 and PM 1 0 , respectively.
Emergency Generators IA, IB, 2A, and 2B were installed in 1972, and Blackout Generators I and 2 were installed in 2004. Potential NOx emissions are estimated to be 122.880 lbs/hr from each of the four emergency generators and 59.200 lbs/hr from each of the two Tennessee Valley Authority
-Sequoyah Nuclear Plant Page 8 blackout 'generators.
An appropriate NOx emission limitation for each of the four emergency generators has been previously determined to be 140.0 lbs/hr (2,242 ppm). An appropriate limitation for the NOx emissions from each of the two blackout generators has been previously determined to be 68.0 Ibs/hr (1,687 ppm). An appropriate limitation has also been previously determined to be 204 hrs/yr for the time of operation of each of the six generators.
This operational limitation is more stringent than the Rule 2.7 limit of 20 days/yr (480 hrs/yr) for the operation of any generator that emits more than 1,500 ppm of NOx. Rule 2.7 also limits the operation of such generators to no more than 5 consecutive days. The NOx emission limitations and operational limitation result in an appropriate NOx emission limitation of 70.992 tons/yr for the six generators combined.
TVA requested all of these limitations in order to qualify as a synthetic minor source. The potential emissions that are given in Table III are based upon the operational limitation.
Potential NOx emissions from the combined eleven small internal-combustion engines that are not required to be permitted are estimated to be 16.145 tons/yr, based on operation, for 480 hrs/yr (the Rule 2.7 limitation).
These emissions were calculated by using emission factors from AP-42 (1996) Table 3.3-1. The sum of these potential NOx emissions, the allowable NOx emissions of 9.0 tons/yr for Auxiliary Boilers A and B combined (Certificate
-08C), and the allowable NOx emissions of 70.992 tons/yr for the six permitted generators combined is 96.137 tons/yr, which is below the Part 70 major source threshold for NOx emissions of 100 tons/yr.Potential particulate emissions from each of Emergency Generators IA, IB, 2A, and 2B are estimated to be 2.676 lbs/hr. The particulate emissions from each of these generators are limited by Rule 10.2 (Schedule
- 1) to 4.07 lbs/br, based.on a process weight for each generator of 1,976 lbs/hr (38.4 MMBtu/hr -0.137 MMBtu/gal x 7.05 lbs/gal).
This limitation is more stringent than the Rule 10.7 particulate emission limit of 0.25 gr/scf(18.75 lbs/hr) for each emergency generator.
Potential particulate emissions from each of Blackout Generators I and 2 are estimated to be 1.289 lbs/hr and 0.31 ton/yr, based on operation for 480 hrs/yr (the Rule 2.7 limitation).
Therefore, the particulate emissions from these generators are subject to Rule 27.3. An appropriate reasonable and proper limitation, in accordance with Rule 27.3, for the particulate emissions from each of Blackout Generators I and 2 has been previously determined to be 1.80 lbs/hr. No controls are necessary in order to achieve this limitation for either generator.
This limitation is more stringent than both the Rule 10.3 (Schedule
- 2) particulate emission limit of 2.27 lbs/hr, based on a process weight for each blackout generator of 952 Ibs/hr (18.5 MMBtu/hr 0.137 MMBtu/gal x 7.05 lbs/gal), and the Rule 10.7 particulate emission limit of 0.25 gr/scf (12.10 lbs/hr) for each blackout generator.
An appropriate limitation for the sulfur content of the diesel fuel that is burned in the six generators has been previously determined to be 0.06% by weight. TVA requested this limitation in order to qualify as a synthetic minor source. Combustion of diesel fuel with the maximum allowable sulfur content in the six generators at their rated capacitiesresults in potential SOx emissions of 2.422 lbs/hr for each of the four emergency generators and 1.17 lbs/hr for each of the two blackout generators.
These SOx emission rates are the effective SOx Tennessee Valley Authority
-Sequoyah Nuclear Plant Page 9 emission limitations for the six generators.
These limitations are more stringent than the Rule 13.1 SO 2 emission limits of 500 ppm (43.5 lbs/hr) for each emergency generator and 500 ppm (28.1 lbs/hr) for each blackout generator.
The VOC emissions from the two blackout generators are subject to BACT (Rule 25.3).It has been determined that no controls are necessary in order to satisfy BACT for these emissions, and no quantitative BACT VOC emissiop limitations are necessary.
The emissions of CO and methane from the two blackout generators dre subject to Rule 23. It has been determined that no controls are necessary in order to satisfy reasonable and proper control technology, in accordance with Rule 23, for these emissions of CO and methane, and no quantitative reasonable and proper limitations are necessary for these emissions.
In addition, no limitations are applicable for the emissions of CO, VOCs, and methane from any of the four emergency generators.
