            Subpart B_Requirements and Recommended Procedures

 

Sec.  240.203-2  Recommended procedures: Design.



    (a) The types, amounts (by weight and volume), and characteristics 

of all solid wastes expected to be processed should be determined by 

survey and analysis. The gross calorific value of the solid wastes to be 

processed should be determined to serve as a basis for design.

    (b) Resource recovery in the form of heat utilization or direct 

recovery of materials should be considered in the design.

    (c) The facility should be designed to be compatible with the 

surrounding area, easy to maintain, and consistent with the land use of 

the area.

    (d) Employee convenience facilities and plant maintenance facilities 

should be provided. Adequate lighting should be provided throughout the 

facility.

    (e) The corrosive and erosive action of once-through and 

recirculated process waters should be controlled either by treating them 

or by using materials capable of withstanding the adverse effects of the 

waters.

    (f) Facility design capacity should consider such items as waste 

quantity and characteristics, variations in waste generation, equipment 

downtime, and availability of alternate storage, processing, or disposal 

capability.

    (g) Facility systems and subsystems should be designed to assure 

standby capability in the event of breakdown. Provision for standby 

water and power should also be considered.

    (h) Instrumentation should be provided to determine such factors as: 

The weight of incoming and outgoing materials (the same scale system may 

be used for both); total combustion airflow rates; underfire and 

overfire airflows and the quantitative distribution of each; selected 

temperatures and pressures in the furnace, along gas passages, in the 

particulate collection device, and in the stack; electrical power and 

water consumption of critical units; and rate of operation. The smoke 

density, the concentration of carbon monoxide, or the concentration of 

hydrocarbons in the stack gases should be monitored. Measurement of the 

pH should be considered for effluent waters. Continuously recording 

instrumentation should be used as much as possible.

    (i) Audible signals should be provided to alert operating personnel 

of critical operating unit malfunctions.

    (j) Sampling capability should be designed into the facility so that 

each process stream can be sampled, and the utilities required to do so 

should be close at hand. The sampling sites should be so designed that 

personnel can sample safely without interfering with normal plant 

operations.

    (k) A laboratory should be included in the design, or provision 

should be made for laboratory analyses to be performed by an outside 

source acceptable to the responsible agency.
