Amend CSHB 1900 (House committee printing) by adding the 
following appropriately numbered SECTIONS to the bill and 
renumbering the subsequent SECTIONS accordingly:
	SECTION ___.  Subchapter B, Chapter 382, Health and Safety 
Code, is amended by adding Section 382.042 to read as follows:
	Sec. 382.042.  EFFECTS SCREENING LEVELS; PENALTY.  (a)  The 
commission by rule shall adopt effects screening levels for air 
contaminants.  Each effects screening level must:
		(1)  be set in a manner that takes into consideration 
all acute and chronic health effects on a person due to exposure to 
an air contaminant;
		(2)  be based in part on the health effects of:                        
			(A)  the one-hour, eight-hour, or 24-hour 
exposure of a person to the air contaminant at the fence-line of an 
emission source; and
			(B)  the lifetime exposure of a person to the air 
contaminant at the fence-line of an emission source; and
		(3)  be set at a level that does not increase the risk 
of cancer in a person exposed to the air contaminant by greater than 
one chance in one million.
	(b)  A person may not cause, suffer, allow, or permit the 
emission of any air contaminant or the performance of any activity 
that causes an effects screening level set by the commission to be 
exceeded.  The commission by rule shall establish requirements for 
assessing a penalty or initiating an action for an injunction 
against a person who violates this subsection.
	(c)  Not later than October 1, 2007, the commission shall 
adopt effects screening levels that comply with the requirements of 
Subsection (a).  Until the commission adopts effects screening 
levels that comply with the requirements of Subsection (a), the 
effects screening levels adopted by the commission as of September 
1, 2005, are interim standards for purposes of this section and 
Section 382.085.  This subsection expires November 1, 2007.
	SECTION ___.  Section 382.042, Health and Safety Code, as 
added by this Act, applies to any violation of an effects screening 
level set by the commission that occurs on or after the effective 
date of this Act.  A violation of an effects screening level that 
occurs before the effective date of this Act is governed by the law 
in effect when the violation occurs, and the former law is continued 
in effect for that purpose.
