§ 125.96 Monitoring requirements.

(a) Monitoring requirements for impingement mortality for existing facilities. The Director may establish monitoring requirements in addition to those specified at § 125.94(c), including, for example, biological monitoring, intake velocity and flow measurements. If the Director establishes such monitoring, the specific protocols will be determined by the Director.

(b) Monitoring requirements for entrainment for existing facilities. Monitoring requirements for entrainment will be determined by the Director on a site-specific basis, as appropriate, to meet requirements under § 125.94(d).

(c) Additional monitoring requirements for existing facilities. The Director may require additional monitoring for impingement or entrainment including, but not limited to, the following:

(1) The Director may require additional monitoring if there are changes in operating conditions at the facility or in the source waterbody that warrant a re-examination of the operational conditions identified at 40 CFR 122.21(r).

(2) The Director may require additional monitoring for species not subject to the BTA requirements for impingement mortality at § 125.95(c). Such monitoring requirements will be determined by the Director on a site-specific basis.

(d) Monitoring requirements for new units at existing facilities. Monitoring is required to demonstrate compliance with the requirements of § 125.94(e).
