SECTION I SOURCE IDENTIFICATION 1. DESCRIPTION OF FACILITY The Western Branch Wastewater Treatment Plant (WWTP) is owned and operated by the Washington Suburban Sanitary Commission (WSSC). The plant treats primarily domestic wastewater and has a design capacity of 30.6 million gallons per day (gpd). It uses an advanced activated sludge process to treat the wastewater. The liquid treatment processes include high rate activated sludge (HRAS) treatment, 1st stage clarification, nitrification, 2nd stage clarification, denitrification, nitrogen stripping, final clarification, filtration, ultraviolet disinfection and aeration. The solids treatment processes include waste sludge holding tanks, dissolved air flotation (DAF) thickeners, thickened sludge storage, centrifuges, two (2) multiple hearth incinerators each equipped with a flue gas recycle system, venture scrubber, wet electrostatic precipitator (WESP) and regenerative thermal oxidizer (RTO). The WESPs and RTOs are new additions replacing two previously existing afterburners, which were removed from the each of the units. The final product from the solids handling processes is the ash resulting from the incineration of the dewatered sludge cake. This ash is transported to a local landfill. Other emission units at the Western Branch WWTP include an emergency diesel generator, methanol storage tanks, and a gasoline storage tank. Two boilers (EU-3 and EU-4), previously used for space heating, along with a fume incinerator, (EU-5) have been taken out of service and rendered inoperable. The facility now uses ultraviolet disinfection and aeration in lieu of chlorination and dechlorination to disinfect the plant effluent. As a result, the facility is no longer subject to 112(r), Risk Management Plan requirements. The SIC code for this facility is 4952. 2. FACILITY INVENTORY LIST

1a.2 Testing Requirements:

Performance Testing, Monitoring, and Calibration Requirements

§62.16015 What are the performance testing, monitoring, and calibration requirements for compliance with the emission limits and standards? You must meet, as applicable, the performance testing requirements specified in paragraph (a) of this section, the monitoring requirements specified in paragraph (b) of this section, the air pollution control device inspections requirements specified in paragraph (c) of this section, and the bypass stack provisions specified in paragraph (d) of this section.

(a) Performance testing requirements. (1) All performance tests must consist of a minimum of three test runs conducted under

conditions representative of normal operations, as specified in §60.8(c). Emissions in excess of the emission limits or standards during periods of startup, shutdown, and malfunction are considered deviations from the applicable emission limits or standards.

(2) You must document that the dry sludge burned during the performance test is representative of the sludge burned under normal operating conditions by: (i) Maintaining a log of the quantity of sewage sludge burned during the performance



of 100

Table IV – 1a 40 CFR Part 62 Subpart LLL test by continuously monitoring and recording the average hourly rate that sewage sludge is fed to the incinerator.

(ii) Maintaining a log of the moisture content of the sewage sludge burned during the performance test by taking grab samples of the sewage sludge fed to the incinerator for each 8 hour period that testing is conducted.

(3) All performance tests must be conducted using the test methods, minimum sampling volume, observation period, and averaging method specified in Table 2 or 3 to this subpart.

(4) Method 1 at 40 CFR part 60, appendix A must be used to select the sampling location and number of traverse points.

(5) Method 3A or 3B at 40 CFR part 60, appendix A-2 must be used for gas composition analysis, including measurement of oxygen concentration. Method 3A or 3B at 40 CFR part 60, appendix A-2 must be used simultaneously with each method.

(6) All pollutant concentrations must be adjusted to 7 percent oxygen using Equation 1 of this section:

Cadj = Cmeas (20.9 − 7) /(20.9 −%O2) Where:

Cadj = Pollutant concentration adjusted to 7 percent oxygen. Cmeas = Pollutant concentration measured on a dry basis. (20.9 − 7) = 20.9 percent oxygen − 7 percent oxygen (defined oxygen correction basis). 20.9 = Oxygen concentration in air, percent. %O2 = Oxygen concentration measured on a dry basis, percent.

(7) Performance tests must be conducted and data reduced in accordance with the test methods and procedures contained in this subpart unless the Administrator does one of the following. (i) Specifies or approves, in specific cases, the use of a method with minor changes in

methodology. (ii) Approves the use of an equivalent method. (iii) Approves the use of an alternative method the results of which he has determined to

be adequate for indicating whether a specific source is in compliance. (iv) Waives the requirement for performance tests because you have demonstrated by

other means to the Administrator's satisfaction that the affected SSI unit is in compliance with the standard.

(v) Approves shorter sampling times and smaller sample volumes when necessitated by process variables or other factors. Nothing in this paragraph is construed to abrogate the Administrator's authority to require testing under section 114 of the Clean Air Act.

(8) You must provide the Administrator at least 30 days prior notice of any performance test, except as specified under other subparts, to afford the Administrator the opportunity to have an observer present. If after 30 days notice for an initially scheduled performance test, there is a delay (due to operational problems, etc.) in conducting the scheduled performance test, you must notify the Administrator as soon as possible of any delay in the original test date, either by providing at least 7 days prior notice of the rescheduled



of 100

Table IV – 1a 40 CFR Part 62 Subpart LLL date of the performance test, or by arranging a rescheduled date with the Administrator by mutual agreement.

(9) You must provide, or cause to be provided, performance testing facilities as follows: (i) Sampling ports adequate for the test methods applicable to the SSI unit, as follows:

(A) Constructing the air pollution control system such that volumetric flow rates and pollutant emission rates can be accurately determined by applicable test methods and procedures.

(B) Providing a stack or duct free of cyclonic flow during performance tests, as demonstrated by applicable test methods and procedures.

(ii) Safe sampling platform(s). (iii) Safe access to sampling platform(s). (iv) Utilities for sampling and testing equipment.

(10) Unless otherwise specified in this subpart, each performance test must consist of three separate runs using the applicable test method. Each run must be conducted for the time and under the conditions specified in the applicable standard. Compliance with each emission limit must be determined by calculating the arithmetic mean of the three runs. In the event that a sample is accidentally lost or conditions occur in which one of the three runs must be discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme meteorological conditions, or other circumstances, beyond your control, compliance may, upon the Administrator's approval, be determined using the arithmetic mean of the results of the two other runs.

(11) During each test run specified in paragraph (a)(1) of this section, you must operate your sewage sludge incinerator at a minimum of 85 percent of your maximum permitted capacity.

(b) Continuous monitor requirements. You must meet the following requirements, as applicable, when using a continuous monitoring system to demonstrate compliance with the emission limits in Table 2 or 3 to this subpart. The option to use a continuous emissions monitoring system for hydrogen chloride, dioxins/furans, cadmium, or lead takes effect on the date a final performance specification applicable to hydrogen chloride, dioxins/furans, cadmium, or lead is published in the Federal Register. If you elect to use a continuous emissions monitoring system instead of conducting annual performance testing, you must meet the requirements of paragraphs (b)(1) through (b)(6) of this section. If you elect to use a continuous automated sampling system instead of conducting annual performance testing, you must meet the requirements of paragraph (b)(7) of this section. The option to use a continuous automated sampling system for dioxins/furans takes effect on the date a final performance specification for such a continuous automated sampling system is published in the Federal Register. (1) You must notify the Administrator 1 month before starting use of the continuous

emissions monitoring system. (2) You must notify the Administrator 1 month before stopping use of the continuous

emissions monitoring system, in which case you must also conduct a performance test within prior to ceasing operation of the system.

PERMIT #24-033-00872 PART 70 OPERATING PERMIT FACT SHEET

Page 1 of 79

BACKGROUND The Western Branch Wastewater Treatment Plant (WWTP) is owned and operated by the Washington Suburban Sanitary Commission (WSSC). The plant treats primarily domestic wastewater and has a design capacity of 30.6 million gallons per day (gpd). It uses an advanced activated sludge process to treat the wastewater. The liquid treatment processes include high rate activated sludge (HRAS) treatment, 1st stage clarification, nitrification, 2nd stage clarification, denitrification, nitrogen stripping, final clarification, filtration, ultraviolet disinfection and aeration. The solids treatment processes include waste sludge holding tanks, dissolved air flotation (DAF) thickeners, thickened sludge storage, centrifuges, two (2) multiple hearth incinerators each equipped with a flue gas recycle system, venturi scrubber, wet electrostatic precipitator (WESP) and regenerative thermal oxidizer (RTO). The WESPs and RTOs are new additions replacing two previously existing afterburners, which were removed from each of the units. The final product from the solids handling processes is the ash resulting from the incineration of the dewatered sludge cake. This ash is transported to a local landfill. Other emission units at the Western Branch WWTP include an emergency diesel generator, methanol storage tanks, and a gasoline storage tank. Two boilers (EU-3 and EU-4), previously used for space heating, along with a fume incinerator (EU-5) have been taken out of service and rendered inoperable. The facility now uses ultraviolet disinfection and aeration in lieu of chlorination and dechlorination to disinfect the plant effluent. As a result, the facility is no longer subject to 112(r), Risk Management Plan requirements. The SIC code for this facility is 4952. The following Table 1 summarizes the actual emissions from Western Branch WWTP based on its Annual Emission Certification Reports for the most recent 5 years: Table 1: Actual Emissions

The major source threshold for triggering Title V permitting requirements in Prince George’s County is 25 tons per year for VOC, 25 tons per year for NOx, 100 tons per year for any other criteria pollutants, 10



Page 2 of 79

tons per year for any single hazardous air pollutant (HAP) or 25 tons per year for total HAPs. Western Branch is a potential major source of NOx. Therefore, the Permittee is required to obtain a Title V-Part 70 Operating Permit under COMAR 26.11.03.01. As a potential major source of NOx, the Facility is subject to the NOx RACT (Reasonable Available Control Technology) requirements of COMAR 26.11.09.08. Western Branch is also subject to the requirements of 40 CFR Part 60 Subpart O (Standard of Performance for Sewage Treatment Plants), 40 CFR Part 60 Subpart Kb (Standard of Performance for Volatile Organic Liquid Storage Vessel …), 40 CFR Part 61 Subpart C (National Emission Standard for Beryllium), and 40 CFR Part 61 Subpart E (National Emission Standard for Mercury). The Facility will be subject to 40 CFR Part 62 Subpart LLL (Federal Plan Requirements for Sewage Sludge Incineration Units constructed on or before October 14, 2010) when the rule becomes effective. The initial compliance date for Subpart LLL is March 21, 2016 Western Branch WWTP is not subject to the requirements of 40 CFR Part 64 (Compliance Assurance Monitoring - CAM), because the incinerators do not meet the applicability requirements for CAM. CAM applicability is discussed further under the CAM heading below. OFF-PERMIT CHANGE The Permittee was issued a construction permit in July 2015 for an “off-permit” change for the installation of a wet electrostatic precipitator (WESP) and a regenerative thermal oxidizer (RTO) to each incinerator. The incinerators were shut down in September of 2012 as a result of a failed energy improvement project, and reactivation of the units is expected in late 2017 or early 2018. The Department received a Title V (Part 70) permit renewal application for Western Branch WWTP on January 2, 2015. An administrative completeness review was conducted and the application was deemed administratively complete. The Permittee was notified of the application completeness decision in a letter dated January 13, 2015.

GREENHOUSE GAS (GHG) EMISSIONS Western Branch emits the following greenhouse gases (GHGs): carbon dioxide, methane, and nitrous oxide. These GHGs are generated from the two incinerators and the Caterpillar diesel engine emergency generator, the main sources of combustion related emissions at the plant. While the new WESPS being installed as part of the reactivation project do not, the two RTOs will emit GHGs.



Page 4 of 79

However, the reactivation project did not constitute a major modification of the existing facility for construction permitting purposes and did not warrant a review as a major modification for PSD and/or NA-NSR as there are no significant non-GHG emissions increases associated with the reactivation. With respect to PSD applicability, GHG are a regulated pollutant for PSD purposes only if another PSD pollutant has a significant increase. While there were no GHG permitting requirements triggered by the reactivation construction permit, the Permittee is required to quantify annually its facility-wide GHG emissions and report them as part of the Emissions Certification Report required under Section 3 of the Part 70 permit. The following table summarizes the actual GHG emissions from WSSC based on its Annual Emission Certification Reports:

Table 3: Greenhouse Gases Emissions Summary COMPLIANCE ASSURANCE MONITORING (CAM) - 40 CFR PART 64 - APPLICABILITY DETERMINATION WSSC WWTP conducted a Compliance Assurance Monitoring (CAM) analysis for the facility and determined that the facility is not subject to the (CAM) Rule 40 CFR Subpart 64. CAM is designed to provide a reasonable assurance of compliance with applicable requirements under the Clean Air Act for large emission units that rely on air pollution control (APC) equipment to achieve compliance. The CAM approach establishes monitoring for the purpose of: (1) documenting continued operation of the control measures within ranges of specified indicators of performance (such as emissions, control device parameters, and process parameters) that are designed to provide a reasonable assurance of compliance with applicable requirements; (2) indicating any excursions from these ranges; and (3) responding to the data so that the cause or causes of the excursions are corrected. In order for a unit to be subject to CAM, the unit must be located at a major source, be subject to an emission limitation or standard; use a control device to achieve compliance; and not otherwise be exempt from CAM. Applicability determinations are made on a pollutant-by-pollutant basis for each emission unit. The pre-control potential particulate emissions (from each incinerator) are less than the CAM applicability threshold of 100 tons per year as shown below:

OVERVIEW OF THE PART 70 PERMIT Section I of the Part 70 Permit contains a brief description of the facility and an inventory list of the emissions units for which applicable requirements are identified in Section IV of the permit. Section II of the Part 70 Permit contains the general requirements that relate to administrative permit actions. This section includes the procedures for renewing, amending, reopening, and transferring permits, the relationship to permits to construct and approvals, and the general duty to provide information and to comply with all applicable requirements. Section III of the Part 70 Permit contains the general requirements for testing, record keeping and reporting; and requirements that affect the facility as a whole, such as open burning, air pollution episodes, particulate matter from construction and demolition activities, asbestos provisions, ozone depleting substance provisions, general conformity, and acid rain permit. This section includes the requirement to report excess emissions and deviations, to submit an annual emissions certification report and an annual compliance certification report, and results of sampling and testing. Section IV of the Part 70 Permit identifies the emissions standards, emissions limitations, operational limitations, and work practices applicable to each emissions unit located at the facility. For each standard, limitation, and work practice, the permit identifies the basis upon which the Permittee will demonstrate compliance. The basis will include testing, monitoring, record keeping, and reporting requirements. The demonstration may

include one or more of these methods. Section V of the Part 70 Permit contains a list of insignificant activities. These activities emit very small quantities of regulated air pollutants and do not require a permit to construct or registration with the Department. For insignificant activities that are subject to a requirement under the Clean Air Act, the requirement is listed under the activity. Section VI of the Part 70 Permit contains State-only enforceable requirements. The section identifies requirements that are not federally enforceable under the Clean Air Act, but solely on Maryland air pollution regulations. These requirements generally relate to the prevention of nuisances and implementation of Maryland's Air Toxics Program. REGULATORY REVIEW/TECHNICAL REVIEW/COMPLIANCE METHODOLOGY Emission Unit EU-1 and EU-2 – Two multiple-hearth incinerators installed in 1977 These are multiple-hearth sewage sludge incinerators, each consisting of 7 hearths. Each hearth is 14.3 feet in diameter. The incinerator is designed to process a maximum of 2160 dry pounds per hour or 9461 dry tons of 35% biosolids per year. Each incinerator is equipped with a venturi scrubber with impingement plate after-cooler for emissions control and is also equipped with a WESP and RTO for controlling particulate matter (PM), volatile organic compounds (VOC) and visible emissions. Exhaust gases from each incinerator are vented to the ambient through a 42-inch diameter, 63 feet tall stack. The existing venture scrubbers were installed in 2009.

The incinerators were originally constructed after June 11, 1973 and combust wastes containing more than 10 percent sewage sludge produced by municipal sewage treatment plants. The incinerators are, therefore, subject to the New Source Performance Standards (NSPS) for opacity and particulate matter, found in 40 CFR Part 60, Subpart O. The incinerators are also subject to the federal National Emission Standard for Hazardous Air Pollutants (NESHAP) for mercury from sewage sludge incineration found in 40 CFR Part 61, Subpart E, and the federal NESHAP for beryllium found in 40 CFR Part 61, Subpart C. The incinerators will be subject to the Federal Plan Requirements for Sewage Sludge Incineration Units constructed on or before October 14, 2010 as found in 40 CFR Part 62 Subpart LLL. Subpart LLL is not yet effective but is expected to become final prior to the initial compliance date of March 21, 2016. Applicable Standards and Limitations

Visible Emissions Standards

A1. COMAR 26.11.08.04B, “In Areas III and IV, a person may not cause or permit the discharge of emissions from any incinerator or hazardous waste incinerator, other than water in an uncombined form, which is visible to human observers.”



Page 7 of 79

Exceptions COMAR 26.11.08.04C – “The requirements of §§A and B of this regulation do not apply to emissions during start-up, or adjustments or occasional cleaning of control equipment if: (1) The visible emissions are not greater than 40 percent opacity; and (2) The visible emissions do not occur for more than 6 consecutive minutes in any 60-minute period.”

A2. 40 CFR Part 60 Subpart O §60.152(a)(2) “On and after the date on which the performance test required to be conducted by §60.8 is completed, no owner or operator of any sewage sludge incinerator subject to the provisions of this subpart shall discharge or cause the discharge into the atmosphere of any gases, which exhibit 20 percent opacity or greater.”

Compliance Demonstration

COMAR 26.11.08.04B (no visible emissions) is more stringent than 40 CFR Subpart O §60.152(a)(2) (20% opacity). Therefore, compliance with the no visible emissions requirement in COMAR 26.11.08.04B will be deemed to be compliance with 40 CFR Subpart O §60.152(a)(2).

Monitoring requirement: The Permittee shall conduct a monthly 1-minute visual observation of the exhaust from each of the scrubbers’ stack. The visual observation must be conducted while the incinerators are in operation. If no visible emissions are observed in six consecutive monthly observations, the Permittee may decrease the frequency of visual observations from monthly to quarterly. If visible emissions are observed during any quarterly visual observation, the Permittee must resume the observation of the scrubber exhaust on a monthly basis and maintain that schedule until no visible emissions are observed in six consecutive monthly visual observations. If visible emissions are observed during any observation, the Permittee must inspect the incinerator and scrubber system for the cause of visible emission and perform necessary adjustments or repairs within 24-hours. If visible emissions have not been eliminated, the Permittee shall perform daily 18-minute visual observation for opacity in accordance with EPA Reference Method 9 when operating the incinerator. [Authority: COMAR 26.11.03.06C]

Record Keeping Requirement: The Permittee shall retain records of the results of visible emissions observations on site for at least five years and make them available to the Department upon request. [Authority: COMAR 26.11.03.06C

Reporting Requirement: The Permittee shall report incidents of visible emissions in accordance with Permit Condition 4, Section III, “Report of Excess Emissions and Deviations.” [Authority: COMAR 26.11.03.06C Compliance Demonstration Discussion: Visible emissions are related to proper operation and maintenance of the incinerators. To assure proper operations and maintenance, the Permittee is required to certify that every incinerator operator satisfactorily completes a



Page 8 of 79

training program that includes the overall operation, maintenance and performance of the facility. As a check on the success of the training program to control visible emissions, a program of monthly or quarterly observations for visible emissions is required in the Part 70 permit.

The Permittee as part of satisfying the requirement to “Report of Excess Emissions and Deviations” Permit Condition 4, Section III to report the incidents implemented a monitoring strategy of focusing a camera on exhaust of the incinerator stacks in order to detect visible emissions. If visible emissions are observed, a plant staff person goes outside to perform an observation. The Permittee submits a quarterly report with the results of the observations.

Compliance Status

No visible emissions have been observed during facility inspections by the MDE’s compliance program. The facility, based upon the camera on the exhaust of the incinerator stacks, reported no visible emissions for 99.9% of the operating time during the past several years before the incinerators were shut down in September of 2012. The incinerators are expected to be reactivated by late 2017 or early 2018. Particulate Emissions Standards

B1 COMAR 26.11.08.05B(2)(b), “Except as provided in Regulations .07, .08, and .08-1 of this chapter, a person may not cause or permit the discharge of particulate matter into the outdoor atmosphere from any incinerator, hazardous waste incinerator, or crematory to exceed 0.03 gr/SCFD when evaluated at 12 percent CO2.”

B2 40 CFR Part 60 Subpart O §60.152(a)(1), “On and after the date on which the performance test required to be conducted by §60.8 is completed, no owner or operator of any sewage sludge incinerator subject to the provisions of this subpart shall discharge or cause the discharge into the atmosphere of particulate matter at a rate in excess of 1.30 lb/ton dry sludge input (0.65 g/kg dry sludge input).”


The testing, monitoring, record keeping, and reporting requirements of 40 CFR Part 60 Subpart O will be the basis for assuring compliance with the COMAR PM standard.

Additional Testing requirements:

(1) The Permittee shall conduct compliance testing of each incinerator within 180 days of the resumption of operation of each incinerator to demonstrate compliance with all applicable regulations and emissions limits for particulate matter. If the Permittee is unable to complete the compliance demonstration during this period, the Permittee shall submit to the Department a written request for an extension to the start-up period.



Page 9 of 79

(2) The Permittee shall submit a stack testing protocol to the Department for review and approval at least 30 days prior to conducting compliance testing. If the testing will be conducted following the same general procedures in the protocol for the prior year, the Permittee may submit in writing any deviation from the previous procedure in lieu of submitting a complete new protocol. All testing shall be done at reasonable times and with at least ten (10) calendar days notice to the Department to allow representation by Department personnel.

Where: Sm = Total mass of sludge charged to the incinerator during the test run. Sv = Total volume of sludge charged to the incinerator during the test run. Qmi = Average mass flow rate calculated by averaging the flow rates at the

beginning and end of each interval "i," kg/hr (ton/hr). Qvi = Average volume flow rate calculated by averaging the flow rates at the

beginning and end of each interval "i," m3/hr (gal/hr). Θi = Duration of interval "i," hr.

(5) Samples of the sludge charged to the incinerator shall be collected in nonporous jars at the beginning of each run and at approximately 1-hour intervals thereafter until the test ends, and "209 F. Method for Solid and Semisolid Samples" (incorporated by reference--see §60.17) shall be used to determine dry sludge content of each sample (total solids residue), except that:

(i) Evaporating dishes shall be ignited to at least 103 ºC rather than the 550 ºC specified in step 3(a)(1). (ii) Determination of volatile residue, step 3(b) may be deleted. (iii) The quantity of dry sludge per unit sludge charged shall be determined in terms of kg/m3 (lb/gal) or kg/kg (ton/ton). (iv) The average dry sludge content shall be the arithmetic average of all the samples taken during the run.

(6) Method 9 and the procedures in § 60.11 shall be used to determine opacity.

Record Keeping Requirement:

The Permittee shall keep the following records on site for at least five years and make them available to the Department upon request.

(a) The final stack tests results. [Authority: COMAR 26.11.03.06C].

(b) “§60.153(c) The owner or operator of any multiple hearth, fluidized bed, or electric sludge incinerator subject to the provisions of this subpart shall retain the following information and make it available for inspection by the Administrator (Department) for a minimum of 5 years:

(2) Daily sampling and analysis of sludge feed in paragraph (b)(5) of this section shall not be required.

(3) Record keeping specified in paragraph (c)(3) of this section shall not be required.”

Note: Applicability of § 60.153(d) above The result of the stack test conducted in June/July of 2010 showed average particulate emission rates of 0.927 lbs/ton for EU-1 and 0.720 lbs/ton for EU-2. The average particulate matter emission rate from EU-1 was greater than 0.75 lbs/ton of sludge input whereas the particulate emission rate for EU-2 was less than or equal to 0.75 lbs/ton of sludge input. As a result, the exemptions under paragraph (d) above apply only to EU-2. The incinerators were shut down in September of 2012 and as a result there are no recent stack tests to report. The incinerators are expected to be up and running in late 2017 or early 2018, at which time a stack test will be conducted, compliance verified, and the various operational parameters discussed above re-established.

Reporting Requirement:

(a) The Permittee shall report the stack test results to the Department within 60 days of completion of the tests [Authority: COMAR 26.11.03.06C].

(b) § 60.155 - Reporting. “(a) The owner or operator of any multiple hearth, fluidized bed, or electric sludge

incinerator subject to the provisions of this subpart shall submit to the Administrator semi-annually a report in writing which contains the following:

(1) A record of the average scrubber pressure drop measurements for each period of 15 minutes duration or more during which the pressure drop of the scrubber was less than, by a percentage specified below, the average scrubber pressure drop measured during the most recent performance test. The percent reduction in scrubber pressure drop for which a report is required shall be determined as follows:



Page 14 of 79

(i) For incinerators that achieved an average particulate matter emission rate of 0.38 kg/Mg (0.75 lb/ton) dry sludge input or less during the most recent performance test, a scrubber pressure drop reduction of more than 30 percent from the average scrubber pressure drop recorded during the most recent performance test shall be reported.

(ii) For incinerators that achieved an average particulate matter emission rate of greater than 0.38 kg/Mg (0.75 lb/ton) dry sludge input during the most recent performance test, a percent reduction in pressure drop greater than that calculated according to the following equation shall be reported:

P = -111E + 72.15

Where P = Percent reduction in pressure drop, and E = Average particulate matter emissions (kg/megagram)”

Note EU-2 is subject to the requirements of § 60.155(a)(1)(i) which sets the reporting threshold at more than 30 percent of the average scrubber pressure drop recorded during the most recent performance test. The average pressure drop during the most recent stack test was 23.5 inches of water column. Therefore the reporting threshold is 16.5 inches of water column.

EU-1 is subject to the requirements of § 60.155(a)(1)(ii) which sets the reporting threshold according to the formula P = -111E + 72.15. This calculates to 21 percent. The average pressure drop during the most recent test was 24.2 inches of water column. Therefore the reporting threshold is 19.2 inches of water column.

The percent reduction of 21 percent in scrubber pressure drop for which a report is required was determined as follows:

P = -111E + 72.15

Where P = Percent reduction in pressure drop, and E = Average particulate matter emissions (kg/megagram)

The average particulate matter emissions from EU-1 was 0.927 lbs/ton Conversion of 0.927 lbs/ton to kg/megagram 0.927 lbs = 1 kg/2.2 lb x 0.927 lbs = 0.421 kg Ton to megagram 2000 lbs = 2000 lb x kg/2.2 lb = 909.09 kg x 1000 = 909090.9 grams x megagrams /1,000,000 gram = 0.909 megagrams

kg/megagram = 0.421 kg/0.909 megagrams = 0.463 kg/megagram

P = -111E + 72.15 P = -111(0.463) +72.15 P = -51.4 +72.15



Page 15 of 79

P = 20.75 (approximately 21 percent)

“(2) A record of average oxygen content in the incinerator exhaust gas for each period of 1-hour duration or more that the oxygen content of the incinerator exhaust gas exceeds the average oxygen content measured during the most recent performance test by more than 3 percent.”

Note: The average O2 contents in the exhaust for EU-1 and EU-2 during the recent stack test were 4.3 and 3.6 percent respectively. Therefore, the Permittee shall maintain a record of the average oxygen content in the incinerator exhaust gas for each period of 1-hour duration or more when the oxygen content of the incinerator exhaust gas exceeds 7.3 percent for EU-1 and 6.6 percent for EU-2.

(c) § 60.155(b) “The owner or operator of any multiple hearth, fluidized bed, or electric sludge incinerator from which the average particulate matter emission rate measured during the performance test required under §60.154(d) exceeds 0.38 g/kg of dry sludge input (0.75 lb/ton of dry sludge input) shall include in the report for each calendar day that a decrease in scrubber pressure drop or increase in oxygen content of exhaust gas is reported, a record of the following: (1) Scrubber pressure drop averaged over each 1-hour incinerator operating period. (2) Oxygen content in the incinerator exhaust averaged over each 1-hour incinerator

operating period. (3) Temperatures of every hearth in multiple hearth incinerators; of the bed and

outlet of fluidized bed incinerators; and of the drying, combustion, and cooling zones of electric incinerators averaged over each 1-hour incinerator operating period.

(4) Rate of sludge charged to the incinerator averaged over each 1-hour incinerator operating period.

(5) Incinerator fuel use averaged over each 8-hour incinerator operating period. (6) Moisture and volatile solids content of the daily grab sample of sludge charged to

the incinerator.”.

Note: Based upon the most recent stack test the requirements of § 60.155(b) applies to EU-1 and not EU-2.

Compliance Status

The Permittee conducted stack testing of the incinerators on June 29, 30, and July 1, 2010. The test showed particulate matter emissions to be 0.0207 gr/dscf for EU-1 and 0.0147 gr/dscf for EU-2 all corrected to 12 percent CO2. The particulate emissions standard (1.30 lbs per ton of sludge input) under Subpart O was also met with emissions rates of 0.927 lbs/ton for EU-1 and 0.720 lbs/ton for EU-2. The average rate was 0.824 lbs/ton of dry sludge input.

The Permittee did comply with the reporting and recordkeeping requirements for pressure drop and excess oxygen.

The incinerators were shut down in September of 2012 and as a result there are no recent stack tests to report. The incinerators are expected to be up and running in late 2017 or



Page 16 of 79

early 2018, at which time a stack test will be conducted, compliance verified, and the operating parameters discussed above reestablished. B3. 40 CFR Part 62 Subpart LLL - Emission Limits and Standards for Existing

The testing, monitoring, record keeping and reporting requirements of 40 CFR Part 62 Subpart LLL are identified in the Fact Sheet by the Part Number “40 CFR Part 62” and located in the Permit in Table IV-1a 40 CFR Part 62 Subpart LLL.

Compliance Status

The initial compliance date is March 21, 2016 or upon restart of the incinerators whichever date is later. Mercury Emissions Standards

C1 40 CFR Part 61 Subpart E §61.52(b)

“ Emissions to the atmosphere from sludge incineration plants, sludge drying plants, or a combination of these that process wastewater treatment plant sludge shall not exceed 3.2 kg (7.1 lb) of mercury per 24-hour period.”


The testing, monitoring, record keeping and reporting requirements of 40 CFR Part 61 Subpart E are presented below.

Testing requirement:

The Permittee shall conduct a performance test on each incinerator for mercury at least once during the term of this permit. Anytime prior to making changes in the operation which would potentially increase emissions above the level determined by the most recent stack test, the Permittee shall estimate by calculation the new emissions level. Testing for mercury shall be conducted in accordance with Method 101A or 105 set forth in Appendix B of Part 61. [Authority: COMAR 26.11.03.06C].

Monitoring requirements:

(1) “…No changes shall be made in the operation [of the incinerators] which would potentially increase emissions above the level determined by the most recent stack test, until the new emission level has been estimated by calculation and the results reported to the Administrator.” [Authority: 40 CFR §61.53(d)(4)].

(2) “All samples shall be analyzed and mercury emissions shall be determined within 30 days after the stack test. Each determination shall be reported to the Administrator by a



Page 17 of 79

registered letter dispatched within 15 calendar days following the date such determination is completed.” [Authority: 40 CFR §61.53(d)(5)].

(3) §61.55- Monitoring of Mercury –not applicable “Wastewater treatment plant sludge incineration and drying plants for which mercury emissions exceed 1.6 kg (1600 grams, 3.5 lb) per 24-hour period, demonstrated either by stack sampling according to §61.53 or sludge sampling according to §61.54, are required to monitor mercury emissions at intervals of at least once per year by use of Method 105 of appendix B or the procedures specified in §61.53 (d) (2) and (4). The results of monitoring shall be reported and retained according to §61.53(d) (5) and (6) or § 61.54 (f) and (g).”

Note: Mercury emissions from the 2010 testing conducted on June 29, 30, and July 1 averaged 0.0139 kg/24 hrs for EU-1 and 0.0183 kg/24 hrs for EU-2; therefore, this monitoring requirement does not apply since the emissions of mercury based on the most recent emissions testing are below the limit of 1.6 kg (1600 grams, 3.5 lb) per 24-hour period stipulated for this requirement.

Record Keeping Requirement:

“Records of emission test results and other data needed to determine total emissions shall be retained at the source and shall be made available, for inspection by the Administrator, for a minimum of 2 years.” [Authority: 40 CFR §61.53(d(6)]. Note: for Part 70 permits, records must be maintained for 5 years.


“All samples shall be analyzed and mercury emissions shall be determined within 30 days after the stack test. Each determination shall be reported to the Administrator [the Department] by a registered letter dispatched within 15 calendar days following the date such determination is completed.” [Authority: 40 CFR §61.53d(5)]. Compliance Status

Mercury emissions from the stack testing conducted on June 29, 30, and July 1, 2010 averaged 13.9 grams/24 hrs for EU-1 and 18.3 grams/24 hrs for EU-2. The Permittee maintains record of all pertinent data at the source and makes them available for inspections, for a minimum of five years as required by the Permittee’s Part 70 (Title V) permit. The Permittee has complied with the record keeping and reporting requirements within the deadlines.

Note: The incinerators were shutdown in September of 2012 and as a result there are no recent stack tests to report. The incinerators are expected to be up and running in late 2017 or early 2018 at which time a stack test will be conducted and compliance verified.

Performance Testing, Monitoring, and Calibration Requirements

§62.16015 What are the performance testing, monitoring, and calibration requirements for compliance with the emission limits and standards? You must meet, as applicable, the performance testing requirements specified in paragraph (a) of this section, the monitoring requirements specified in paragraph (b) of this section, the air pollution control device inspections requirements specified in paragraph (c) of this section, and the bypass stack provisions specified in paragraph (d) of this section.

(a) Performance testing requirements.



Page 30 of 79

(1) All performance tests must consist of a minimum of three test runs conducted under conditions representative of normal operations, as specified in §60.8(c). Emissions in excess of the emission limits or standards during periods of startup, shutdown, and malfunction are considered deviations from the applicable emission limits or standards.

(2) You must document that the dry sludge burned during the performance test is representative of the sludge burned under normal operating conditions by: (i) Maintaining a log of the quantity of sewage sludge burned during the

performance test by continuously monitoring and recording the average hourly rate that sewage sludge is fed to the incinerator.

(ii) Maintaining a log of the moisture content of the sewage sludge burned during the performance test by taking grab samples of the sewage sludge fed to the incinerator for each 8 hour period that testing is conducted.

(3) All performance tests must be conducted using the test methods, minimum sampling volume, observation period, and averaging method specified in Table 2 or 3 to this subpart.

(4) Method 1 at 40 CFR part 60, appendix A must be used to select the sampling location and number of traverse points.

(5) Method 3A or 3B at 40 CFR part 60, appendix A-2 must be used for gas composition analysis, including measurement of oxygen concentration. Method 3A or 3B at 40 CFR part 60, appendix A-2 must be used simultaneously with each method.

(6) All pollutant concentrations must be adjusted to 7 percent oxygen using Equation 1 of this section:

Cadj = Cmeas (20.9 − 7) /(20.9 −%O2) Where:

Cadj = Pollutant concentration adjusted to 7 percent oxygen. Cmeas = Pollutant concentration measured on a dry basis. (20.9 − 7) = 20.9 percent oxygen − 7 percent oxygen (defined oxygen correction basis). 20.9 = Oxygen concentration in air, percent. %O2 = Oxygen concentration measured on a dry basis, percent.

(7) Performance tests must be conducted and data reduced in accordance with the test methods and procedures contained in this subpart unless the Administrator does one of the following. (i) Specifies or approves, in specific cases, the use of a method with minor

changes in methodology. (ii) Approves the use of an equivalent method. (iii) Approves the use of an alternative method the results of which he has

determined to be adequate for indicating whether a specific source is in compliance.

(iv) Waives the requirement for performance tests because you have demonstrated by other means to the Administrator's satisfaction that the affected SSI unit is in compliance with the standard.



Page 31 of 79

(v) Approves shorter sampling times and smaller sample volumes when necessitated by process variables or other factors. Nothing in this paragraph is construed to abrogate the Administrator's authority to require testing under section 114 of the Clean Air Act.

(8) You must provide the Administrator at least 30 days prior notice of any performance test, except as specified under other subparts, to afford the Administrator the opportunity to have an observer present. If after 30 days notice for an initially scheduled performance test, there is a delay (due to operational problems, etc.) in conducting the scheduled performance test, you must notify the Administrator as soon as possible of any delay in the original test date, either by providing at least 7 days prior notice of the rescheduled date of the performance test, or by arranging a rescheduled date with the Administrator by mutual agreement.

(9) You must provide, or cause to be provided, performance testing facilities as follows: (i) Sampling ports adequate for the test methods applicable to the SSI unit, as

follows: (A) Constructing the air pollution control system such that volumetric flow

rates and pollutant emission rates can be accurately determined by applicable test methods and procedures.

(B) Providing a stack or duct free of cyclonic flow during performance tests, as demonstrated by applicable test methods and procedures.

(ii) Safe sampling platform(s). (iii) Safe access to sampling platform(s). (iv) Utilities for sampling and testing equipment.

(10) Unless otherwise specified in this subpart, each performance test must consist of three separate runs using the applicable test method. Each run must be conducted for the time and under the conditions specified in the applicable standard. Compliance with each emission limit must be determined by calculating the arithmetic mean of the three runs. In the event that a sample is accidentally lost or conditions occur in which one of the three runs must be discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme meteorological conditions, or other circumstances, beyond your control, compliance may, upon the Administrator's approval, be determined using the arithmetic mean of the results of the two other runs.

To demonstrate continuous compliance with the emission limits and standards specified in Table 2 or 3 to this subpart, use the procedures specified in paragraph (a) of this section. In lieu of using the procedures specified in paragraph (a) of this section, you have the option to demonstrate initial compliance using the procedures specified in paragraph (b) of this section for particulate matter, hydrogen chloride, carbon monoxide, dioxins/furans (total mass basis or toxic equivalency basis), mercury, nitrogen oxides, sulfur dioxide, cadmium, lead, and fugitive emissions from ash handling. You must meet the requirements of paragraphs (a) and (b) of this section, as applicable, and paragraphs (c) through (e) of this section, according to the performance testing, monitoring, and calibration requirements in § 62.16015(a) and (b). You may also petition the Administrator for alternative monitoring parameters as specified in paragraph (f) of this section.

(a) Demonstrate continuous compliance using a performance test. Except as provided in paragraphs (a)(3) and (e) of this section, following the date that the initial performance test for each pollutant in Table 2 or 3 to this subpart is completed, you must conduct a performance test for each such pollutant on an annual basis (between 11 and 13 calendar months following the previous performance test). The performance test must be conducted using the test methods, averaging methods, and minimum sampling volumes or durations specified in Table 2 or 3 to this subpart and according to the testing, monitoring, and calibration requirements specified in § 62.16015(a). (1) You may conduct a repeat performance test at any time to establish new values

for the operating limits to apply from that point forward. The Administrator may request a repeat performance test at any time.

(2) You must repeat the performance test within 60 days of a process change, as defined in § 62.16045.

(3) Except as specified in paragraphs (a)(1) and (2) of this section, you can conduct performance tests less often for a given pollutant, as specified in paragraphs (a)(3)(i) through (iii) of this section.



Page 45 of 79

(i) You can conduct performance tests less often if your performance tests for the pollutant for at least 2 consecutive years show that your emissions are at or below 75 percent of the emission limit specified in Table 2 or 3 to this subpart, and there are no changes in the operation of the affected source or air pollution control equipment that could increase emissions. In this case, you do not have to conduct a performance test for that pollutant for the next 2 years. You must conduct a performance test during the third year and no more than 37 months after the previous performance test.

(ii) If your SSI unit continues to meet the emission limit for the pollutant, you may choose to conduct performance tests for the pollutant every third year if your emissions are at or below 75 percent of the emission limit, and if there are no changes in the operation of the affected source or air pollution control equipment that could increase emissions, but each such performance test must be conducted no more than 37 months after the previous performance test.

(iii) If a performance test shows emissions exceeded 75 percent of the emission limit for a pollutant, you must conduct annual performance tests for that pollutant until all performance tests over 2 consecutive years show compliance.

(b) Not Applicable at this time (c) To demonstrate compliance with the dioxins/furans toxic equivalency emission

limit in paragraph (a) or (b) of this section, you must determine dioxins/furans toxic equivalency as follows: (1) Measure the concentration of each dioxin/furan tetra- through octachlorinated-

isomer emitted using Method 23 at 40 CFR part 60, appendix A-7. (2) For each dioxin/furan (tetra- through octachlorinated) isomer measured in

accordance with paragraph (c)(1) of this section, multiply the isomer concentration by its corresponding toxic equivalency factor specified in Table 5 to this subpart.


(d) You must submit an annual compliance report as specified in § 62.16030(c). You must submit a deviation report as specified in § 62.16030(d) for each instance that you did not meet each emission limit in Table 2 and 3 to this subpart.

(e) If you demonstrate continuous compliance using a performance test, as specified in paragraph (a) of this section, then the provisions of this paragraph (e) apply. If a force majeure is about to occur, occurs, or has occurred for which you intend to assert a claim of force majeure, you must notify the Administrator in writing as specified in § 62.16030(f). You must conduct the performance test as soon as practicable after the force majeure occurs. The Administrator will determine whether or not to grant the extension to the performance test deadline, and will notify you in writing of approval or disapproval of the request for an extension as soon as practicable. Until an extension of the performance test deadline has been approved by the Administrator, you remain strictly subject to the requirements of this subpart.
