PUBLIC NOTICE

1144 Control of Stationary Generator Emissions

SAN # 2011-07

1. TITLE OF THE REGULATIONS:

Amendment to 7 DE Admin. Code 1144 Control of Stationary Generator Emissions

2. BRIEF SYNOPSIS OF THE SUBJECT, SUBSTANCE AND ISSUES:

The Division of Air Quality (DAQ) is proposing to amend 7 DE Admin. Code 1144 to update the language based upon recent EPA promulgations for similar engines, and to make minor corrections to the regulatory requirements. When finalizing 7 DE Admin. Code 1144 in 2005, DAQ stated that the EPA’s “Tier 4” standards would not be required for new, emergency generators if Tier 4 standards ultimately required aftermarket controls to meet the limits. Because Tier 4 standards do require aftermarket controls, DAQ plans to amend the regulation to be consistent with EPA’s New Source Performance Standards for internal combustion engines by requiring new, emergency generators to simply meet the Tier 2 or 3 standards, as the regulation already requires.

DAQ is also proposing new recordkeeping and reporting requirements for certain non-emergency generators which are operated in conjunction with a voluntary demand-reduction program or any other interruptible power supply arrangement with a utility, other market participant, or system operator. These new recordkeeping and reporting requirements will allow the DAQ to better understand how many non-emergency generators are participating in such programs, and will help the DAQ to gauge their compliance.

Additionally, the regulation will be amended to lower the diesel sulfur requirement of the regulation from 500ppm to 15ppm to be consistent with EPA requirements. Other planned amendments include removing the sulfur content provisions for natural gas, since the generator owner has no control of the sulfur content in the pipeline natural gas which is received. Also, various definitions and regulatory requirements will be clarified and minor errors in the regulatory text shall be corrected.

7.0 Emissions Certification, Compliance, and Enforcement

7.1 Emissions Certification of New Distributed Generators by a Supplier. A supplier may seek to certify that its generators, which are meant to be installed as new distributed generators, meet the provisions of this regulation.

7.1.1 Certification Process. Emissions of nitrogen oxides, nonmethane hydrocarbons, particulate matter, carbon monoxide, and carbon dioxide from the generator shall be certified in pounds of emissions per megawatt hour (lb/MWh) at International Organization for Standardization (ISO) conditions or at the load conditions specified by the applicable testing methods in Emissions. Compliance with this regulation shall be demonstrated through testing using the applicable EPA Reference Methods, California Air Resources Board methods, or equivalent test methods approved by the Department if: 7.5.1 of this regulation. If the design of a certified generator is modified, the generator will need to be re-certified. Certification means that a generator meets the required emissions standards of this regulation and can be installed, as supplied, for use as a distributed generator. With respect to nitrogen oxides, nonmethane hydrocarbons, carbon monoxide, and carbon dioxide, test results from US EPA Reference Methods, California Air Resources Board methods, or equivalent testing may be used to verify this certification. When testing the output of particulate matter from liquid-fuel reciprocating engines, ISO Method 8178 shall be used. Test results shall be provided upon request to the Department. A statement attesting to certification shall be displayed on the nameplate of the unit or on a label attached to the unit with the following text:

This generator has met the standards defined by 7 DE Admin. Code 1144 and is certified as meeting applicable emission levels when it is maintained and operated in accordance with the supplier’s instructions.

7.1.2 Responsibility of Supplier. Certification will apply to a specific make and model of generator. For a make and model of a generator to be certified, the supplier shall certify that the generator is capable of meeting the requirements of this regulation for the lesser of 3,000 hours of operation or five years.

7.2 Emissions Certification of New Emergency Generators by a Supplier. An engine that has been certified to meet the currently applicable US EPA non-road or NSPS emissions standards for internal combustion engines shall be deemed to be certified for use in new emergency generators.

7.3 Emissions Verification by an Owner. An owner shall verify, by each generator’s respective compliance date as detailed in 1.3 of this regulation, that a generator complies with its respective emission requirements of 3.0 of this regulation by submitting any or all of the following types of data to the Department for review:

7.3.1 any emissions certification of a new distributed generator as detailed in 7.1 of this regulation;

7.3.2 any emissions certification of a new emergency generator as detailed in 7.2 of this regulation;

7.3.3 any maintenance or operating requirements/instructions provided by the generator manufacturer;

7.3.4 the type, or a description, of any emission control equipment used; or

7.3.5 emissions test data for the generator (such as a manufacturer’s technical data sheet), any supporting documentation for any emission control equipment used, any supporting calculations, any quality control or assurance information, and any other information needed to demonstrate compliance with the requirements.

7.4 Reverification. To ensure continuing compliance with the emissions limitations, the owner or operator shall verify a distributed generator’s compliance with the emission standards every five years. This verification may be accomplished by following a maintenance schedule that the manufacturer certifies will ensure continued compliance with the required standards, by third party testing of the distributed generator using appropriate test methods to demonstrate that the distributed generator still meets the required emission standards, or by some other means as proven to the Department.

7.5 Testing

7.5.1 Emissions. Compliance with this regulation shall be demonstrated through testing using the applicable US EPA Reference Methods including those specified in 40 CFR Parts 89, 90, 91, 92, 94, 1039, or 1048 (July 1, 2004 Edition) and 40 CFR Part 60, Subparts IIII and JJJJ (July 1, 2011 Edition), California Air Resources Board methods, or equivalent test methods approved by the Department or US EPA if:

7.5.1.1 a supplier is seeking to certify that one of its generators meets the provisions of this regulation, pursuant to 7.1 of this regulation;

7.5.1.2 an owner owns a generator that is not certified or verified under the terms of 3.1.2, 7.1, 7.2, or 7.3 of this regulation; or

7.5.1.3 an owner of a generator is seeking to reverify the generator via third party testing pursuant to 7.4 of this regulation.

7.5.2 Sulfur Content.

7.5.2.1 Sulfur limits pursuant to 5.1 of this regulation shall be determined using the applicable sampling and testing methodologies set forth in 40 CFR 80.580 (July 1, 2004 2011).

7.5.2.2 Sulfur limits pursuant to 5.2, 5.3, 5.4, or 5.5 of this regulation shall be determined using the applicable sampling and testing methodologies set forth in the Gas Processors Association (GPA) Standard 2140-97 Liquefied Petroleum Gas Specification and Test Methods, Appendix D of 40 CFR 75 (July 1, 2004), or in the South Coast Air Quality Management District’s Rule 431.1 “Sulfur Content of Gaseous Fuels” (June 12, 1998).

7.6 Duty to Comply. An owner or operator shall comply with the requirements of this regulation. Neither certification nor compliance with this regulation relieves owners or operators from compliance with any other applicable state and federal regulations or permitting requirements.

7.7 This regulation is enforceable by the Department as provided by law.

8.0 Credit for Concurrent Emissions Reductions

8.1 Flared Fuels. If a generator uses fuel that would otherwise be flared (i.e., not used for generation or other energy related purpose), the emissions that were or would have been produced through the flaring can be deducted from the actual emissions of the generator, for the purposes of calculating compliance with the requirements of this regulation. If the actual emissions from flaring can be documented, they may be used as the basis for calculating the credit, subject to the approval of the Department. If the actual emissions from flaring cannot be documented, then the following default values shall be used:

Emissions

Waste, Landfill,

Digester Gases

Nitrogen Oxides

0.1 lbs/MMBtu

Particulate Matter

N/A

Carbon Monoxide

0.7 lb/MMBtu

Carbon Dioxide

117 lb/MMBtu

8.2 Combined Heat and Power.

8.2.1 CHP installations shall meet the following requirements to be eligible for emissions credits related to thermal output:

8.2.1.1 At least 20% of the fuel’s total recovered energy shall be thermal and at least 13% shall be electric. This corresponds to an allowed power-to-heat ratio range of between 4.0 and 0.15.

8.2.1.2 The design system efficiency shall be at least 55%.

8.2.2 A CHP system that meets the requirements of CHP installations shall meet the following requirements to be eligible for emissions credits related to thermal output: of this regulation may receive a compliance credit against its actual emissions based on the emissions that would have been created by a conventional separate system used to generate the same thermal output. The credit shall be subtracted from the actual generator emissions for purposes of calculating compliance with the limits in 3.1 or 3.2 of this regulation. The credit will be calculated according to the following assumptions and procedures:

8.2.2.1 The emission rates for CHP facilities that replace existing thermal systems (e.g., boiler) for which historic emission rates can be documented shall be the historic emission rates in lbs/MMBtu, but not more than the emission rates for new facilities that displace a thermal system, which are:

Emissions

Maximum Rate

Nitrogen Oxides

0.2 lbs/MMBtu

Particulate Matter

N/A

Carbon Monoxide

0.08 lbs/MMBtu

Carbon Dioxide

117 lbs/MMBtu

8.2.2.2 The emissions rate of the thermal system in lbs/MMBtu will be converted to an output-based rate by dividing by the thermal system efficiency. For new systems the efficiency of the avoided thermal system will be assumed to be 80% for boilers or the design efficiency of other process heat systems. If the design efficiency of the other process heat system cannot be documented, an efficiency of 80% will be assumed. For retrofit systems, the historic efficiency of the displaced thermal system can be used if that efficiency can be documented and if the displaced thermal system is either enforceably shut down and replaced by the CHP system, or if its operation is measurably and enforceably reduced by the operation of the CHP system.

8.2.2.3 The emissions per MMBtu of thermal energy output will be converted to emissions per MWh of thermal energy by multiplying by 3.413 MMBtu/MWhthermal.

8.2.2.4 The emissions credits in lbs/MWhthermal, as calculated in 8.2.2.3 of this regulation, will be converted to emissions in lbs/MWhemissions by dividing by the CHP system power-to-heat ratio.

8.2.2.5 The credit, as calculated in 8.2.2.4 of this regulation, will be subtracted from the actual emission rate of the CHP unit to produce the emission rate used for compliance purposes.

8.2.2.6 The mathematical calculations set out in 8.2.2.1 through 8.2.2.4 of this regulation are expressed in the following formula:

(8-1)

8.3 Non-Emitting Resources. When electricity generation that does not produce any of the emissions regulated herein is installed and operated simultaneously at the facility where the generator is installed and operated, then the electricity savings supplied by the non-emitting electricity source shall be added to the electricity supplied by the generator for the purposes of calculating compliance with the requirements of this regulation, subject to the approval of the Department and in accordance with the following formula for determining such savings:

(8-2)

where

RateEF = effective emission rate of generator, accounting for non-emitting

resource or sources (lb/MWh);

RateA = actual emission rate of generator alone (lb/MWh);

SizeA = actual prime power rating of generator (MW);

SizeNER = total generating capacity of non-emitting resource or sources (MW).
