<br />paIORI~Y OBJECTIVE NUMBER 2 <br />AIR POLLUTION CONTROL <br /> <br />I-" <br />-3 <br />~ <br />I-" <br /> <br />Work towards achieving ambient air quality standards in non-attainment areas and <br />minimize air quality degradation in clean air areas. <br /> <br />Sub-Objective One: Develop a program to identify, characterize and control <br />emissions of fine (10 micron) particulate matter to protect human health and <br />welfare and preserve and enhance urban visibility. <br /> <br />Rationale: The haze over urban area skies is a significant concern to the State of <br />Colorado. There are two aspects to the problem - health dangers and visibility <br />reduction. The current approaches used to monitor, model, and identify control <br />measures are not comprehensive enough to address a revised particulate standard <br />based upon the size of the particulate matter. <br /> <br />A great deal of information has been collected in developing the particulate <br />criteria document and the associated EPAstaff recommendation. This material will <br />be used by EPA in setting the primary and secondary particulate standards. <br />Proposal of this standard is currently scheduled for 1982. Technical means to <br />address the new standard need to be developed concurrently. <br /> <br />Milestones <br /> <br />Respons ibil ity <br /> <br />Comp;Letion Date <br /> <br />Development of statewide monitoring <br />considering: <br />-monitor locations <br />-types <br />-logistics in terms of operational <br />complexity <br />-additional laboratory needs <br /> <br />CDR <br /> <br />1982-83 <br /> <br />Promulgation of particulate standards. <br /> <br />EPA <br /> <br />1982 <br /> <br />Review of current levels of air quality <br />in state in regard to IPIO,(Inhalable <br />particulates to 10 microns) level. <br /> <br />CDR <br /> <br />1983 <br /> <br />Initid SIP revision activity <br /> <br />CDR/EPA Ongoing <br />EPA Ongoing <br />EPA Ongoing <br />CDR Ongoing <br />CDR 4-7 mo. after <br /> standard <br /> <br />Incorporation of IPIO data into <br />inventory teChniques. <br /> <br />Development and validation of dispersion <br />models. <br /> <br />Development of ambient reference method. <br /> <br />Implementation of monitoring network <br /> <br />-26- <br />
