Mr, Smith's telephone ! number ia (303) 236-5210. It would also be advisable to provide a technical contact for him to call if he should have any : questions about the transmittal. ' Two other iasuea have been discussed with Mr. Smith In regard to the workplan. First, it was pointed out that it may be inappropriate to assume that all erneIters can meet the 1.5 standard or that all smelters have adequate ambient data. The Bureau recognises this and are not making these assumptions in their study. Second, it was pointed out that it ia unlikely that much particle size or inlet loading data are available other than possibly some engineering estimates used in specifying existing equipment. The Bureau also recognises this limitation and have only stated "idealized" data requirements in their workplan. TTease contact me at (303) 231-0683 if you have any further questions or concerns about the timing and approach discussed above. RJGinc Attachment cct R Crosier H. Poling R.

STUDY Scops, Workplan, and Schedula (revised 11/18/85) Scopes The purpoee of this study le to examine the technics! feasibility and the anticipated coata of modifying all existing U.S. primary lead plants from current SPA ambient air lead ' compliance of 1.5 ug/M3 to anticipated EPA ambient air compliance of 0.5 ug/M3. The project ie planned to commence the week of 11/17/85 and end the week of 02/23/85. Plant evaluations will Include Herculaneum, K0 (St. Joe)} Bulck, MO UMAX); Glover, MO (ASARCO) amelter/refiner complsxss end the East Helena, MX (ASARCO) smelter. Iha El Paio, TX, amelter and the Omaha, NE refiner (both ASARCO) are not Included. Workplans . 1. Data collection A. Plant specific date 1. Plot plana locating ambient air monitoring stations ' 2. Quarterly average data for each monitoring station 3. Significant non-compliance data for each monitoring station a. Identify point and fugitive source(a) of non-compliance b. Identify time frame 4. Plant plan views showing each source 5. Emission data a. Test data for point source(a) ______ b. Bast available date or estimates for fugitive source(s) Motet Ideal data would Include Inlet and outlet loadings at conditions, particle size distribution at inlet and outlet, lead analysis by gnrtiela sine 6. Any available engineered designs for fugitive dust control 7. Any performance data, curves, ...etc, relative to control devices B, Vendor performance data on control devices 1. Bfflcisuey curves 2. Energy curves 11. Vendor and plant performance data analysis Motet If analysis indicates 0.5 ug/M3 IS NOT TECHNICALLY FEASIBLE using existing technology, present conclusions and end project. If anelysls indicates 0.3 ug/M3 IS TECHNICALLY FEASIBLE using existing technology, proceed to III. " III.* Individual plant analyals. Analysis will Include change In capital and operating coats. No economic computer modeling Is included. A. Analysis of Glover, HQ (ASARCO) . B. Analysis of Herculaneum, MO (St. Joe) C. Analysis of Bulck, MO (AMAX) S, Analysis of E. Helena, KT (ASARCO) IV.
