The NFPA 70E Standard details multiple levels of Hazard Risk Categories (HRC) [see table 1.1], also called Levels. The greater the risk: the higher the HRC. Arc Rating is the factor that indicates which HRC is necessary, and can be measured in either ATPV or EBT.
The optimal pH range for brook trout appears to be 6.5-8.0,with a tolerance range of 4.0-9.5.Brook trout occur in waters with a wide range of alkalinity and specificconductance, although high alkalinity and high specific conductance usuallyincrease brook trout production (Cooper and Scherer 1967).
Many anglers feel that brown trout tend to be more wary and challenging to catch than brook or rainbow trout. Spring stocking include 1.8 million brown trout, 89,000 of which are two year old fish that average thirteen inches.ach year the DEC stocks around 2.3 million catchable-size brook, brown and rainbow trout in almost 300 lakes, ponds and roughly 3,100 miles of streams across the state.
