Is the facility a major source for HAP? (see definition below) Major sources are any stationary source or group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit considering controls, in the aggregate, 10 tons per year (TPY) or more of any hazardousairpollutant or 25 TPY or more of any combination of HAP.

Are there one or more off-site waste management or recovery operations at the facility subject to the Off-Site Waste and Recovery Operations (OSWRO) MACT (40 CFR 63, subpart DD)?

If no for any of the above, please explain:

Please provide the following information about all startup and shutdown events:

, (EP021), Shredder (EP023), and the Squeezer System (EP023); as well as the control device 

### 1. What emissions source types experience startup and shutdown events? The United States Court of Appeals for the District of Columbia Circuit vacated portions of two provisions in the EPA’s CAA section 112 regulations governing the emissions of HAP during periods of startup, shutdown and malfunction (SSM). Sierra Club v. EPA, 551 F.3d 1019 (D.C. Cir. 2008). Specifically, the Court vacated the SSM exemption contained in 40 CFR 63.6(f)(1) and 40 CFR 63.6(h)(1), that are part of a regulation, commonly referred to as the “General Provisions Rule,” that the EPA promulgated under section 112 of the CAA. When incorporated into CAA section 112(d) regulations for specific source categories, these two, now vacated, provisions exempted sources from the requirement to comply with the otherwise applicable CAA section 112(d) emission standard during periods of SSM. To be consistent with the Court’s decision, facilities must comply with the applicable standards at all times.

For each emission source type, do the annual emissions estimate in the Enclosure 2A "Emissions (TPY)" field include the annual emissions from startup and shutdown events that you added in the "STARTUP EMISSIONS (TPY)" and "SHUTDOWN EMISSIONS (TPY)" fields? Please enter a separate response for each emissions point type below:

How does the startup or shutdown event compare to normal operations (e.g., differences in flowrate, temp., pressure, alternate fuels used, alternate control devices used, etc.)? 1.a. Under normal operating conditions, do these emissions sources operate continuously? 1.b. What triggers the equipment to experience a startup or shutdown event (e.g. hot startup, startup after an emergency shutdown, re-start, control device startup)?

9.a. Please describe how HAP emissions would be minimized.

9.b. How much would it cost to minimize HAP emissions in this manner?

9.c. How much would HAP emissions be reduced compared to an uncontrolled event? (If "emission factor" is used as basis for emissions estimate, please provide the emission factor and sources of the emission factor.1

9. During startup and shutdown events, if you cannot comply with the emissions limitation and/or work practices in the regulation that apply during normal operation, what is the minimum emissions level that could be achieved?
