Northeast Nuclear Energy Company hereby proposes to incorporate the following proposed changes to the ETS. | |||
Specifically, NNECo proposes to delete sections 4.3, Lobster Habitat Sampling; and 4.5, Intake Velocity Profile Me'asurements, as these programs have been completed and their respective reports have been submitted. | |||
In addition, NNECo proposes to modify sections 3.1.2.1.5, Benthic Survey; and 3.1.2.1.7, Trawling; as indicated on the attached sheets. These proposals concern improvements in sampling frequencies and locations based upon analyses of existing data. | |||
Finally, NNECo proposes to delete section 3.1.2.1.8, Ichthyoplankton and Zooplankton Survey; as this program was to terminate after December, 1975. | |||
