				the early stages of the construction of a facility. In addition, manufacturer's
				information on equipment must be available to the plant operator before unit
				start up.

				including sampling techniques, monitoring requirements, and sample
				analysis.
(h) Recordkeeping
				procedures and sample forms to be used.
(i) A maintenance schedule that incorporates
				manufacturer's recommendations, preventative maintenance and housekeeping
				schedules, and special tools and equipment usage.
