d. Instrumentation, controls and SCADA system components will be
evaluated by an instrumentation engineer.
Electrical power distribution systems will be evaluated by an electrical
engineer. Electrical standby generators will be evaluated by an electrical
engineer and mechanical engineer.
Roadways, access drives, parking areas and walkways will be assessed by
a civil engineer.
3. Each discipline engineer will prepare a memorandum that summarizes the
findings from the site visit including the specific condition assessment results as
well as larger planning issues such as opportunities to improve energy efficiency
or enhance performance and reliability. Provide recommendations for
maintenance, such as coatings and other restorative measures.
F. Comprehensive Plant Evaluation

1.
Treatment Plant Unit Process Analysis: This subtask includes documentation of
existing conditions (completed under Task F), treatment capacities, present needs,
and anticipated future needs based on appropriate design standards and anticipated
future requirements. Future considerations will include potential effluent standards
based on general EPA permitting trends in the watershed and also the preliminary
draft NPDES permit. The following major systems will be included in the
comprehensive plant evaluation:
