Proposed Rule
LSA Document #06-434

DIGEST

Amends 326 IAC 11-7-3 concerning municipal waste combustion emission limits. Repeals 326 IAC 11-7-9 concerning the compliance schedule for municipal waste combustion units. Effective 30 days after filing with the Publisher.


HISTORY
IC 13-14-9-7 Notice of Comment Period: October 11, 2006, Indiana Register (DIN: 20061011-IR-326060434FDA).
Notice of First Hearing: October 11, 2006, Indiana Register (DIN: 20061011-IR-326060434PHA).
Date of First Hearing: December 6, 2006.

PUBLIC COMMENTS UNDER IC 13-14-9-4.5
IC 13-14-9-4.5 states that a board may not adopt a rule under IC 13-14-9 that is substantively different from the draft rule published under IC 13-14-9-4 until the board has conducted a third comment period that is at least 21 days long. Because this proposed rule is not substantively different from the draft rule published on October 11, 2006, at DIN: 20061011-IR-326060434FDA, the Indiana Department of Environmental Management (IDEM) is not requesting additional comment on this proposed rule.

SUMMARY/RESPONSE TO COMMENTS FROM THE SECOND COMMENT PERIOD
IDEM requested public comment from October 11, 2006, through November 13, 2006, on IDEM's draft rule language. No comments were received during the second comment period.

SUMMARY/RESPONSE TO COMMENTS RECEIVED AT THE FIRST PUBLIC HEARING
On December 6, 2006, the Air Pollution Control Board (board) conducted the first public hearing/board meeting concerning the development of amendments to 326 IAC 11-7. No comments were made at the first hearing.


SECTION 1. 326 IAC 11-7-3 IS AMENDED TO READ AS FOLLOWS:

326 IAC 11-7-3 Emission limits

Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11
Affected: IC 13-15; IC 13-17


Sec. 3. The concentration of pollutants contained in the gases discharged to the atmosphere from a designated facility shall not exceed the following limits:
Pollutant  Emission Limits 
Particulate matter  23 25 milligrams per dry standard cubic meter (mg/dscm)4 1 
Opacity  10% based on a 6-minute average 
Cadmium  0.040 0.035 mg/dscm1 
Lead  0.44 0.400 mg/dscm1 
Mercury  0.080 0.050 mg/dscm; or 15% of the potential mercury emissions concentration1, 3, 4 
Sulfur dioxide  29 parts per million by volume (ppmv); or 20% of the potential sulfur dioxide emission concentration3,5 
Hydrogen chloride  29 ppmv; or 5% of the potential hydrogen chloride emissions concentration2,3 
Organic emission (expressed as total mass dioxins/furans)  30 nanograms per dry standard cubic meter (ng/dscm) total mass1 
Nitrogen oxides  205 ppmv2 
Carbon monoxide5  100 ppmv6 5(based on a 4-hour block averaging time) 
1Corrected to seven percent (7%) oxygen. 
2Corrected to seven percent (7%) oxygen, dry basis. 
3Whichever concentration is less stringent. 
4 Corrected to twelve percent (12%) carbon dioxide. 
5 4Corrected to seven percent (7%) oxygen, dry basis, calculated as a 24-hour daily geometric mean. 
6 5Measured at the combustor outlet in conjunction with a measurement of oxygen concentration, corrected to seven percent (7%) oxygen, dry basis, calculated as an arithmetic mean. 
(Air Pollution Control Board; 326 IAC 11-7-3; filed Jan 18, 1999, 1:20 p.m.: 22 IR 1968; readopted filed Jan 10, 2001, 3:20 p.m.: 24 IR 1477)
