Q

wa64ty f4wc2 1900 Compliance 1. Monitoring of our kilns consists of monitoring temperature and pressure by zone. There are 10 thermocouples of which 3 make automatic control changes. The PC fan is also monitored for speed and damper settings, which controls the pressure.
2. Monitors are in place for process control only 3. Before providing cost information we would like to know how you intend to use this data to assure that we are providing the proper information.
4. We do rlot operate periodic kilns 5. Yes, we have testing ports on our stacks. Our tunnel kilns are subject to emissions limits via the Title V and federally enforceable limit to 10 tph. As such we perform periodic tests for S02 and particulates. Our current low production rates would be a hindrance to any stack tests. Our dryers do not have stacks that would be available for any type of testing.
6. We do not perfotm HAP tests and do not have the necessary testing costs to supply. However, the total cost is much more involved than just the actual invoiced test costs. Prior to the test day the work load is reviewed to verify that the kiln will be operating at or near maximum and that the product mix is typical. The day before the stack test the product that will be moving through the kiln during the test is recorded. The day of the test significant time is involved to oversee and review the testing. Afterwards test results must be developed, reviewed and filed.
7. I am unaware of any methods acceptable as a replacement for stack testing; however, mass balance testing could be a viable option.
8. Our kilns operate under 10 tph and as such are uncontrolled. As noted below we are concemed that being required to install any type of APCD would be detrimental to our continued operation.
9. We believe that there should remain a subcategory for 10 tph. Additionally, an investigation into the feasibility of a Health Based Alternative and combining of all gaseous HAPs rather than individual limits, as discussed at the SER meeting, is warranted. 1400 South Mahoning Ave. Alliance, Ohio 44601

Capital Available/Regulatory Impact 1. Our kilns are permitted by a Title V in Ohio. If we were requir ed to install an APCD, as we are currently uncontrolled, the costs indicated on page 17 of your presentation are our best indicator. The annual operating cost would more than double our current facility costs. The cost to install an APCD would be more than 20% of our net company value. Using our average income over the last five years, and subtracting the additional operating cost, it is extremely unlikely that we could ever earn enough to recoup this investment. The magnitude of these costs is very large, and potentially enough to drive us out of business. The cost indicated to install an APCD is for one kiln only. As we certainly could not afford to install two devices, we would be forced to permanently shutdown one kiln and cap our production. However, economics aside, we do not believe that the installation of an APCD on an older small kiln is a feasible option due to the technical difficulties involved with the original design and functionality of the kiln.
