Rulemaking

¡ EPA will be establishing numerical emissions limits regulating 9 pollutants for existing and new 

SSI units under Section 129 (solid waste incineration) of the Clean Air Act

¡ New Source Performance Standards (NSPS) and Emission Guidelines (EG) for SSI units 

l Pursuant to Clean Air Act (CAA) section 111 and 129

¡ Schedule

l Proposal – Currently scheduled for June 30, 2010 

¡ 30 day public comment period

¡ Option for public hearing, if requested

l Promulgation – December 16, 2010 (court-ordered)
3

Background: Why will EPA be regulating SSI units?

¡ June 2007 Commercial Institutional Solid Waste Incinerator (CISWI) rule vacated and 

remanded 

l Court held that any solid waste material (e.g. sewage sludge) combusted in any 

unit must be regulated under 129

¡ April 29, 2010 Office of Solid Waste and Emergency Response (OSWER) proposes 

new definition of solid waste 

l Sewage sludge that is incinerated, is considered a solid waste

l SSI units are subject to section 129, combustion of solid waste

¡ No current standards in place for SSI units under section 129

l EPA received a petition for reconsideration requesting SSI units be covered under 

the Other Solid Waste Incinerator Rule (OSWI)

l EPA will establish SSI standards separate from OSWI 

¡ Additionally, credit for reductions of urban hazardous air pollutants
4

Background: Inventory of Units

¡ Incinerating sewage sludge is one method of disposal

¡ SSI units are typically located at wastewater treatment plants

l 231 units at 126 facilities in 24 states across the U.S and Puerto Rico

¡ Majority are publically owned by municipalities

¡ 3 entities, privately owned

¡ 0, Indian Country 

l Types of Units currently in operation

¡ 63 Fluidized Bed (FB)

¡ 168 Multiple Hearth (MH)

Overview of CAA Section 129

¡ EPA is required to establish numerical emissions limits for existing and new units for each 

category of solid waste incineration units

¡ Numerical limits for PM, CO, D/F, SO2, NOX, HCl, Pb, Hg, and Cd

¡ Section 129(a)(2) provides criteria for EPA (Maximum Available Control Technology “MACT” floor)

l EPA may distinguish units into subcategories based on class, type, and size

l For existing sources:

¡ “...standards shall not be less stringent than the average emissions limitation achieved 

by the best performing 12% of units...”

l For new sources:

¡ “...standards shall not be less stringent than the emissions control that is achieved in 

practice by the best controlled similar unit...”

l EPA must consider beyond the floor

¡ Cost of achieving such emission reduction

¡ Any non-air quality health and environmental impacts and energy requirements

¡ Section 129(e) requires all solid waste incineration units to operate in accordance with a Title V 

permit

¡ Section 129(a)(5) requires EPA to conduct a review and revise as appropriate any promulgated 

standards every five years
8

Proposed Standards and Requirements

¡ Numerical limits for PM, CO, D/F, SO2, NOX, HCl, Pb, Hg, and Cd + opacity

¡ EPA anticipates some units will need to install additional control devices and improve work management 

practices

l Fabric filter (PM, Cd, Pb), packed bed scrubber (HCl, SO2), activated carbon injection (Hg, D/F) 

l Specifications for process parameters (maximum feed rate, minimum pressure drop or amperage, flow rate, 

pH, temperature, etc.)

¡ Testing

l Initial compliance tests 

l Option: annual performance tests or continuous emissions monitoring system (CEMS)

¡ Allowance for less frequent testing (criteria)

¡ Monitoring

l Process parameters (opacity, control calibration and monitoring, leak detection pressure drop, etc.) 

¡ Recording Keeping and Reporting

l Annual report

l Deviation report

l Qualified operator status report

¡ Continuous Compliance

l Demonstrated by maintaining operating limits (process parameters)

l Annual pollution control device inspections (self inspect)

¡ Intent to require all sources to obtain Title V permit
9

Cost

¡ Cost <$100 million, however, preliminary emissions reductions benefits will trigger a major rule 

¡ Cost to comply (fabric filter, packed bed scrubber, activated carbon injection)

l 44 of 108 owners (40%) can meet limit for existing sources

l Small Entities (municipalities <50,000 population) will find landfilling to be least expensive

l Total Capital Cost if all current units comply with standard: $245,043,493 

¡ Just large sources (>50,000 population): $194,517,122

l Total Annual Cost (with Capitol Recovery) if all units to comply with standard: $80,041,807 

¡ Just large sources (>50,000 population): $62,464,230

¡ Alternative to standard: Landfilling Option

l 99 of 108 owners (92%) will find landfilling to be the least expensive option

¡ Includes units that can already comply

l Total Annual Cost for Landfill Option: 

¡ Approach A: minimum cost factors, higher landfill cost 

l All units: -$68,608,725

l Small sources (<50,000 population): -$6,491,244

¡ Approach B: higher cost factors, landfill option is least expensive

l All units: -$515,928,297

l Small sources (<50,000 population): -$83,098,0828
10

Flexibilities

¡ Note: CAA mandates a minimum stringency (i.e., MACT Floor) which is independent 

of cost or economic factors 

¡ Beyond the Floor, cost and other factors considered

¡ Monitoring, recording keeping, and reporting

l Option: Annual stack test or continuous emissions monitoring (CEMS)

l Potential allowance for less frequent monitoring

*All estimates are for the implementation year (2015), and are rounded to two significant figures so numbers may not sum across columns. All fine 

particles are assumed to have equivalent health effects, but the benefit per ton estimates vary because each ton of precursor reduced has a different 

propensity to become PM2.5. These benefits incorporate the conversion from precursor emissions to ambient fine particles. 12

From: Stephen D. Page, Director, Office of Air Quality Planning and Standards 

Subject: Consultation on EPA's Proposed New Source Performance Standards (NSPS) and 

Emission Guidelines (EG) for Sewage Sludge Incinerators: Executive Order 13132, 

"Federalism" 

The purpose of this e-mail is to seek your consultation and input on the Environmental 

Protection Agency's (EPA) forthcoming proposed rule to develop air emission standards for 

sewage sludge incinerators (SSI). Pursuant to Clean Air Act (CAA) Sections 111 and 129, EPA 

will be proposing new source performance standards (NSPS) and emission guidelines (EG) for 

existing sources for the SSI source category. EPA would like to invite you to a meeting to be 

held at the USEPA Ariel Rios Building, on May 27, 2010, from 2:00 p.m. to 4:00 p.m. in Room 

5530. The Ariel Rios North Building is located at 1200 Pennsylvania Avenue, NW, Washington, 

DC 20004. 

Consultation is requested pursuant to the terms of Executive Order 13132, entitled 

"Federalism," which directs federal agencies to consult with elected state and local government 

officials, or their representative national organizations, when developing regulations and policies 

that impose substantial compliance costs on state and local governments. We currently estimate 

that up to approximately 126 facilities owning 231 SSI units that may be affected by this action 

are owned by state/local jurisdictions. To that end, the purpose of this meeting is to provide you 

with general background on the rule, answer any questions you may have, and seek your formal 

written input pursuant to the Order. Please refer to the e-mail attachment titled “Enclosure 1” for 

a list of potentially affected facilities. 
Pursuant to this consultation process, EPA is contacting the National Governors' 

Association, National Conference of State Legislatures, National League of Cities, U.S. 

Conference of Mayors, National Association of Counties, National Association of Towns and 

Townships, County Executives of America, Council of State Governments, International 

City/County Management Association, and Environmental Council of the States to inform them 

and seek their input for this rulemaking. Additionally, EPA will be inviting National Association 

of Clean Air Agencies (NACAA) and the Association of State and Interstate Water Pollution 

Control Administrators (ASIWPCA), to serve as technical advisors to the Big Ten during this 

consultation. As EPA has already consulted extensively with the National Association of Clean 

Water Agencies (NACWA), they also will be invited to participate, to also serve as technical 

advisors to the Big Ten during this consultation. 

EPA is under court order to promulgate the final rule by December 16, 2010, so in order 

to meet this deadline we are anticipating a proposal date of June 30, 2010. While we would 

appreciate any input you can provide us at the briefing, you will have the opportunity to provide 

written input within 20 days after the meeting. Please let us know if you will be able to attend by 

contacting Andrew Hanson in EPA's Office of Congressional and Intergovernmental Relations at 

hanson.andrew@epa.gov or at 202-564-3664. 

If you have questions or concerns regarding the rule or the consultation process, you may 

contact Robin Dunkins of EPA’s Office of Air Quality Planning and Standards at 

dunkins.robin@epa.gov or 919-541-5335.
