PURPOSE AND SCOPE The purpose of this environmental standard review plan (ESRP) is to direct the staf f's description and evaluation of the applicant's preapplication, site preparation and construction, and preoperational hydrelogical monitoring programs.
The scope of the review directed ' y this plan includes evaluations of (1) the accuracy of data, (2) adequacy of data collection, and (3) ana ~ytical methods used in the hydrological monitoring programs.
If elements of the monitoring programs are determined to be inadequate, recommendations for supplemental programs will be prepared.
II.
REQUIRED DATA AND INFORMATION The kinds of data and information required will be af fected by site-and station-specific factors, and the degree of detail will be modified according to the anticipated magnitude of the potential impacts.
lhe followinp data or information will usually be required:
A.
Maps showing (1) features of the plant and site, including the bound-aries and bathymetry of all surf ace water bodies (including springs) adjacent to the site both before and after construction activities; (2) the locations of all hydrological (including groundwater monitoring wells), thermal, and aquatic biological monitoring stations; (3) locations of all wells potentially influ-enced by plant construc; ion and operation; and (4) major geomorphic features (e.g., floodplains) and regional geology (from the ER).
B.
Site vicinity surface-and ground water average and extreme velocities and flow rates (f rom ESRP 2.3.1 and the ER).
C.
Sediment transport (suspended anc bed load) characteristics and erod-ability of the site soil (from ESRP 2.3.1 and the ER).

The type and frequency of data collected at each 10 ation as well as the duration of each monitoring program (from the ER).
E.
Descriptions of the monitoring equipment used (from the ER).
F.
Descriptions of the data analysis procedures used (from the ER).

ANALYSIS PROCEDURE In this analysis, the reviewer will consider the following se;.arate but related aspects of the applicant's hydrological monitoring progra;,i:
Preapplication monitoring.
The program of field monitoring and data collections used to support the applicant's hydrological descriptions.
Site preparation and construction monitoring.
The proposed program of hydrological monitoring to control anticipated impacts from site preparation and construction and to detect any unexpected impacts arising from these activ-ities. This program may include preconstruction monitoring to establish a base-line for assessing the subsequent impacts of site preparation and construction.
This monitoring will be required only in unusual circumstances when specific adverse imoacts are predicted.
Preoperational monitoring. The proposed program af hydrological moni-toring to establish a baseline for identifying and assessing environmental impacts resulting from plant operation.
A.
Preapplication Monitoring Information from tt.e applicant's preapplication monitoring program is used to aid in the assessment of site acceptabi!ity and to support the staff's data base as needed to identi fy surf ace-or ground-water system impacts that 108 M6 6.3-3
February, 1979 could result from construction and operation of the proposed piant. Generally, data are needed on a seasonal basis and should be suf ficient to characterize seasonal variat ons throughout at least one annual cycle.
The reviewer will analyze the available data to determine that they are adequate to support the environmental descriptions of ES Section 2.3 and the impact analyses of ES aections 4.2, 5.2, 5.3.1 and 5.3.2.
The following factors should be considered in the analysis:
Location and number of monitoring stations (and wells) as reqr, ced to consider the following f actors:
a.
Bathymetric characteristics of surface waters in site vicinity.
b.
Soil and ground-water system charact. eristics in the site
- vicinity, c.
The type of cooling system employed and its operating noder d.
Type of sanitary and chemical waste retention method.
e.
Transient hydrological parameters in the site /icinity.
2.
Sampling f requency and times to ensure that importan temporal variations (e.g., tidal variations) were adequately monitored.
3.
Duration of monitoring programs.
4.
Sediment tran: port characteristics.

Site Preparation and Construction Monitoring Construction monitoring will be required when specific adverse impacts are predicted (e.g.,
impact due to dewatering, inc* ' _ ad turbidity).
The reviewer will determine these predicted impacts from the output of the environmental reviews of ES Sections 4.2 and 4.3 and will analyze the proposed monitoring programs associated with these predicted impacts.
C.
Preoperational Monitoring The preoperational monitoring program is designed to provide the data base necessary for evaluating any hydrologic changes arising from operation of the proposed plant.
The applicant's preoperational monitoring plan should be analyzed to determine if adequate baseline data will be available to assess the following:
1.
Tne alteration of surf ace-water flow fields in the site vicinity.
2.
Alteration of ground water flow (e.g., saltwater intrusion).
?
Impact of sani tary and chemical waste retention methods on ground-water quality.
4.
Alteration of sediment transport.
IV.
EVALUATION The reviewer's evaluation of these monitoring programs must establish whether suf ficient and adequate data will be provided to accomplish the goals of the programs as outlined above. Where the program is,iudged to be inadeuuate or to inc'ude unnecessary elem 2,.ts, the reviewer will recommend additions and deletions as required.
The reviewer will ensure that all such recommendations are consistent with NRC policy and requirements established by the EPA or 0;ner

February, 1979 State agencies responsible for the determinations specified in the Federal Water Pollution Control Act (FWPCA).
The following features should be evaluated when applicable:
A.
The intensity of sampling r2 quired for each anticipated impact It should be commensurate with the degree of impact expected.
B.
Validity of data.
C.
Compliance with requirements of State and Federal agencies.
L Adequacy of data measurement techniques.
Where outputs of a preceding monitoring program or project demonstrate no significant impacts, provisions to study such effects in successive monitoring programs may be reduced or deleted.
V.
INPUT TO THE ENVIRONMENTAL STATEMENT ES Section 6.3 should describe results of the preapplication monitoring program review, and present the objectives of the site preparation, construc-tion, and preoperational hydrological monitoring prtgrams eithout detail.
The reviewer will provide a brief outiiae of monitoring station locations and the methods, frequency, and duration of monitoring used in each case.
Tables and maps may be used if appropriate.
Where the monitoring programs have been found inadecuate, the reviewer's recommendations for modi fying the programs should be included.
The reviewer will provide inputs or ensure that inputs will be made to the following ES sections:
