Amend HB 2129 by adding the appropriately numbered sections 
as follows:    
	SECTION __.  Subchapter B, Chapter 382, Health and Safety 
Code, is amended by adding Sections 382.0161, 382.0162, 382.042, 
and 382.043 to read as follows:
	Sec. 382.0161.  MONITORING REQUIREMENTS FOR MAJOR SOURCES.  
(a)  In this section, "major source" has the meaning assigned by 
Title V of the federal Clean Air Act (42 U.S.C. Section 7661).
	(b)  In addition to other monitoring requirements under this 
chapter, the commission by rule shall require the owner or operator 
of a major source to:
		(1)  provide for daily fence-line monitoring of the 
emission of air contaminants from the major source; and
		(2)  make and maintain records on the measuring and 
monitoring of the emissions.
	(c)  In providing for the daily fence-line monitoring of 
emissions as required by this section, the owner or operator of the 
major source must:
		(1)  provide for at least two monitors with each of the 
monitors placed on opposite sides of the source;
		(2)  provide for a sufficient number of monitors so 
that the maximum distance measured along the fence-line between 
each monitor is one-eighth of a mile; and
		(3)  place the monitors in such a way that the monitors 
are evenly spaced.
	(d)  The owner or operator of a major source shall designate 
an independent consultant approved by the commission to certify to 
the commission that the major source is in compliance with this 
section.  A member, employee, or agent of the commission may examine 
during regular business hours the monitoring equipment or any 
records or memoranda relating to the monitoring equipment required 
under this section.
	(e)  The commission by rule shall require the owner or 
operator of a major source to submit for the executive director's 
approval a list of the air contaminants that the owner or operator 
will monitor under this section.  To be eligible for approval, the 
list must include:
		(1)  each hazardous air pollutant listed under 42 
U.S.C. Section 7412 of the federal Clean Air Act that is applicable 
to the major source; and
		(2)  any other air contaminant that the executive 
director or a local municipal or county air pollution control 
agency requests that the owner or operator monitor.
	(f)  The commission may adopt rules allowing for the owner or 
operator of a major source to request an exemption from the 
fence-line monitoring requirements of this section.  To be eligible 
for an exemption, the owner or operator must submit to the executive 
director for approval an alternative monitoring plan that 
demonstrates continuous or semi-continuous monitoring of each 
stack, vent, flare, cooling tower, or other device for which 
technologically feasible monitoring devices are available.  The 
owner or operator shall review the plan at least once every five 
years to identify additional monitoring opportunities based on new 
technology and submit proposed changes to the executive director 
for approval.
	Sec. 382.0162.  COMMISSION PROGRAMS CONCERNING THE IMPACT OF 
AIR CONTAMINANTS ON PUBLIC HEALTH.  (a)  The commission, in 
conjunction with the Department of State Health Services, the 
Mickey Leland National Urban Air Toxics Research Center, 
universities located in this state, and other leading researchers, 
shall establish the programs described by this section.  The 
purposes of the programs are to:
		(1)  prevent public health problems in this state;                     
		(2)  improve understanding of the effects of emissions 
of air contaminants from a variety of sources on public health in 
this state; and
		(3)  improve the legislature's ability to develop the 
best public policies for ensuring better public health in this 
state.
	(b)  The commission shall conduct personal exposure 
monitoring as part of the TexAQS II ozone field research program to 
improve the understanding of the relationship between emissions of 
ozone-forming air contaminants, particularly highly reactive 
volatile organic compounds, and public health effects, such as 
asthma.
	(c)  The commission, in conjunction with leading state and 
national researchers and policymakers, annually shall host an air 
toxics workshop concerning the effects of emissions of air 
contaminants on individuals who experience outdoor, indoor, or 
personal exposure to the air contaminants, to advance this critical 
field of study in this state.
	(d)  The commission shall issue grants for research 
concerning the effects of emissions of air contaminants on public 
health, including research concerning the deployment or 
development of low-cost, effective personal exposure monitoring 
technology.
	(e)  The commission shall conduct an exposure study to map 
the levels of air contaminants in a community that is located near a 
concentration of industrial sources of air contaminants.  The study 
must evaluate the effects of emissions of air contaminants on 
public health by monitoring over a one-year period the total 
outdoor, indoor, and personal exposure of individuals who are 
exposed to emissions of air contaminants in those communities.  The 
commission shall integrate data collected during the course of the 
study with available ambient monitoring data and provide the 
legislature with a report concerning the integrated data not later 
than January 1, 2007.  This subsection expires September 1, 2007.
	Sec. 382.042.  EFFECTS SCREENING LEVELS.  (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)  Not later than January 1, 2006, the commission shall 
assemble a panel of independent, nationally recognized experts in 
the fields of toxicology, epidemiology, medicine, and public health 
to review the commission's effects screening levels and to 
recommend standards to the commission that comply with the 
requirements of Subsection (a).  The panel shall consider the 
effects screening levels, methods, and programs of other states as 
part of the review.  The panel must provide opportunities for public 
comment in conducting the review.  The panel shall make 
recommendations to the commission regarding the commission's 
effects screening levels, methods, and programs not later than July 
1, 2007.  Not later than October 1, 2007, the commission shall adopt 
effects screening levels as required under Subsection (a) that take 
into consideration the panel's recommendations.  The owner or 
operator of an emission source must comply with the effects 
screening levels set by the commission under this section not later 
than January 1, 2009.  This subsection expires September 1, 2009.
	(c)  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 Sections 382.043 and 382.085.  
This subsection expires November 1, 2007.
	Sec. 382.043.  SANCTIONS; REPORT.  (a)  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 
section.
	(b)  The commission annually shall publish a report that 
lists each violation of this section.  The report must include any 
instance in which the commission suspected a violation but later 
determined that the evidence was not sufficient or credible enough 
to amount to a violation of this section.
	SECTION __.  Section 382.085, Health and Safety Code, is 
amended by amending Subsection (a) and adding Subsections (c)-(e) 
to read as follows:
	(a)  A [Except as authorized by a commission rule or order, 
a] person may not cause, suffer, allow, or permit the emission of 
any air contaminant or the performance of any activity that causes 
or contributes to, or that will cause or contribute to, either in 
isolation or in conjunction with air contaminants from other 
sources, a condition of air pollution.
	(c)  For purposes of this section, a condition of air 
pollution is considered to exist if credible evidence demonstrates 
an unacceptable risk of health effects due to air pollution as 
determined by:
		(1)  a measured level of an air contaminant in excess of 
an effects screening level for the air contaminant for a relevant 
period as provided by commission rule;
		(2)  a measured level of multiple air contaminants that 
in conjunction with one another increase the risk of cancer in a 
person exposed to the air contaminants by greater than one chance in 
one million;
		(3)  a measured level of multiple air contaminants that 
are associated with the same chronic health condition and that in 
conjunction with one another are likely to result in a greater risk 
to an exposed person's health than would one of the contaminants in 
isolation if measured at the relevant effects screening level for 
the contaminant; or
		(4)  any other evidence that is of sufficient value and 
credibility to demonstrate an injurious or adverse effect to human 
health or welfare, animal life, vegetation, or property, or as to 
interfere with the normal use and enjoyment of animal life, 
vegetation, or property.
	(d)  In addition to any other remedy authorized by law, the 
commission by rule shall establish requirements for assessing a 
penalty or initiating an action for an injunction against a person 
who violates this section.
	(e)  If the commission brings an action for a violation of 
this section, the burden is on the owner or operator of the facility 
or source, through certification by a responsible official, to 
demonstrate to the commission that the facility or source:
		(1)  is in compliance with all technological 
requirements applicable to the facility or source;
		(2)  is in compliance with all monitoring requirements 
applicable to the facility or source; and
		(3)  is not aware of any evidence that demonstrates 
that the facility or source has caused or contributed to a condition 
of air pollution in violation of this section.
	SECTION __.  (a)  Not later than September 1, 2006, the owner 
or operator of a major source must provide for the fence-line 
monitoring of air contaminants as required by Section 382.0161, 
Health and Safety Code, as added by this Act.
	(b)  Not later than January 1, 2006, the Texas Commission on 
Environmental Quality shall adopt requirements for assessing a 
penalty or initiating an action for an injunction against a person 
who violates Section 382.043, Health and Safety Code, as added by 
this Act, or Section 382.085, Health and Safety Code, as amended by 
this Act.
	(c)  Not later than March 1, 2006, the Texas Commission on 
Environmental Quality shall publish an annual report listing 
violations of effects screening levels as required by Section 
382.043, Health and Safety Code, as added by this Act.
	(d)  Section 382.085, Health and Safety Code, as amended by 
this Act, applies only to a violation of Section 382.085, Health and 
Safety Code, that occurs on or after the effective date of this Act.  
A violation of Section 382.085, Health and Safety Code, that occurs 
before the effective date of this Act is governed by the law in 
effect when the violation occurred, and the former law is continued 
in effect for that purpose.
	(e)  Section 382.043, 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.
	SECTION 4.  This Act takes effect September 1, 2005.
