Proposed Rule. Second Notice. 

OPINION .AND ORDER OF THE BOARD (by J. Theodore Meyer): 

This matter is before the Board on the Illinois Environmental 

Protection Agency's (Agency) August 19, 1991 proposal. The 

proposal is intended to regulate particulate matter with an 

aerodynamic diameter less than or equal to a nominal 10 

micrometers, which is known as PM-10. This proposal is directed at 

the Mccook and Lake Calumet areas of Cook County, and at the 

Granite City area of Madison County. The proposal represents one 

part of Illinois's submittal of a complete state implementation 

plan (SIP) for the control of PM-10 emissions, pursuant to section 

189 of the Clean Air Act, as amended in 1990, Illinois was to adopt 

and submit its plan by November 15, 1991. 

Procedural History 

The Board accepted the proposal for hearing on August 22, 

1991, and sent the proposal to first notice on August 26, 1991. 

The proposal was first published in the Illinois Register on 

September 20, 1991, at 15 111.Reg. 13627. 

On September 30, 1991, the Agency moved to substantially amend 

its proposal by adding rules necessary for the Granite City area to 

show compliance. On October 10, 1991, the Board granted that 

motion to amend, but noted that because of the complexity of the 

new proposal, the Illinois Administrative Procedure Act (APA) 

required that the entire proposal be again published for first 

notice. (111.Rev.Stat. 1989, ch. 1271, par. 1001 et seq.) The 

Board noted that returning to first notice would delay completion 

of the rulemaking, and that there vas no possibility of even 

reaching second notice before the November 15, 1991 federal 

deadline. As it had pointed out in its August 22 and August 26 

orders, the Board again stated that because the proposal was filed 

on August 19, 1991, Illinois law made it literally impossible, 

since the day the proposal was filed, to meet the federal deadline. 

The Board granted the Agency's motion to amend, and stated that it

212.109 Measurement Methods for Opacity 

Except as otherwise provided in this. Part, and except for tha 

methods of data reduction when applied to Sections 212.122 and 

212.123. measurements of opacity shall be conducted in accordance 

with Method 9. 40 CFR Part 60. Appendix A. incorporated bv 

reference in Section 212.113. except that for roadways and 

parking areas the number of readings reouired for each vehicle 

pass will be three taken »t S-second intervale. The first 

reading shall be at the point of maximum opacity and second and 

third readings shall be made at the same point, the observer 

standing at right angles to the Plume at least 15 feet awav from 

the Plume and observing 4 feet above the surface of the roadway 

or parking area. After four vehicles have passed, the 12 

readings will be averaged.

flow rate and gas velocity shall be determined in 

accordance with 40 CFR 60, Appendix A, Methods 1, IA, > 

2, 2A, 2C, 2D, 3 and 4, incorporated by reference in 

Section 212*113.

to the presence or absence of visible emissions from 

all process emission sources and fugitive particulate 

emission sources required to meet a "no-visible 

cmioaiono" atandagd. except with respect to Section 

2i2faoi, shall be conducted in accordance with 40 CFR 

60, Appendix A, Method 22, incorporated by reference in 

Section 212.113. except that the length of the 

observing period shall be at the discretion of the 

observer, but not less than one minute.
