Response Summary for Comments Received on draft Indirect Discharge Permit ID-9-0036 December, 2005 The draft indirect discharge permit ID-9-0036 was placed on public notice from November 14, 2005 to December 13, 2005. Duringthis period.comments were received on the draft permit. Those comments, and the Department's response to those comments, are listed below:
Comment:
I am curious to know a bit more about the process and law behind the NPDES. You mentioned in your informative e-mail to me-that there is a "section" that applies to the permit ("14-503(d)").
Is that Vermont law? Can you tell me where that is in the Vermont Statutes Annotates? Is there also some federal law that applies, and, if so what would that be?
Response
ID-9-0036 is an Indirect Discharge Permit for the discharge of septic tank effluent through leachfields to the groundwater and eventually to the Connecticut River.
The Indirect Discharge Permit program is based on Vermont Statute: 10 V.S.A. Chapter 47, Sections 1259 and 1263. There is no federal law which applies to this permit program; it is unique to Vermont. Indirect Discharge Permits are not NPDES permits.
The Section 14-504(d) is from the Indirect Discharge Rules, effective 4/30/03. The Indirect Discharge Rules are on our Wastewater Management Division website:

Entergy Nuclear Vermont Yankee, LLC Discharge Permit ID-9-0036 Page 13 E3.
Groundwater Monitoring:
A.
Chemical and Bacteriological Monitoring: (continued)
For the purpose of this section, therefore, weekly groundwater measurements are required in April and October. Once a well is sampled, no further groundwater level measurements will be required for that well for that month.
The results of these analyses shall be submitted to the Secretary prior to the 15th day of the second month following the date of sampling.
B.
Groundwater Levels:
The Quality Control/Quality Assurance plan includes the location of a minimum of six groundwater monitors installed around the Main, C.O.B.
and New Warehouse disposal systems each, three groundwater monitors installed around the New Office Building disposal fields, two groundwater monitors located downgradient of the C.O.B. mound (Northwest) leachfield, and two groundwater monitors installed around the Governor Hunt and Gatehouse #1 disposal systems each, to monitor the level of the ground water table. Upon request by the Secretary, the depth to groundwater (below ground surface) shall be measured and recorded at a frequency determined by the Secretary above that required in E3(A) above. Any such request would be in the form of a letter to the permittee.
E4.
Receiving Stream Monitoring:
Indirect Discharge Permits normally require regular chemical and biological monitoring of the receiving waters. Due to the extremely large stream flow to effluent flow ratio at low median monthly flow (approx. 63,782:1), and the size of the Connecticut River at the point of compliance, stream water quality monitoring is not required for this system. However, if the Secretary determines stream monitoring to be necessary, the permittee shall submit, upon written notice from the Secretary, sampling procedures for chemical and biological sampling of the receiving waters within 90 days of receiving such notice. The requirement for sampling and the frequency of such sampling will be upon written notice from the Secretary.
E5.
Summary Water Quality Evaluation:
By June 30, 2010 the permittee shall have a qualified water quality specialist submit an evaluation to the Secretary of all past effluent and groundwater quality data and determine what, if any, short or long term impacts there have been on groundwater quality. If chemical and biological monitoring of the receiving waters was conducted, the results of that monitoring shall also be evaluated.
Entergy Nuclear Vermont Yankee, LLC Discharge Permit ID-9-0036 Page 14 E6.
Sampling and Testing Procedures:
All wastewater, groundwater and surface water sampling, preservation, handling and test procedures used to comply with the monitoring requirements herein shall conform to procedures specified in the most.current edition of Standard Methods for the Examination of Water and Wastewater APHA - AWWA - WPCF, and the Vermont Water Quality Standards unless written approval of an alternate method is received from the Agency.
E7.
Miscellaneous:
If the permittee monitors any required parameter set forth in this permit for this treatment and disposal system more frequently than required by this permit, the results of such monitoring shall be included on the Discharge Monitoring Report Form.
All records and information resulting from the monitoring activities required by this permit including all records of analyses performed and calibration and maintenance of instrumentation and recordings from continuous monitoring instrumentation shall be retained for a minimum of three (3) years, or longer if requested by the Secretary. Records shall include laboratory bench sheets showing exact location, time and composites of sample as well as analytical procedures used, interim results obtained and all calculations supporting the reported test results.
E8.
Additional Monitoring:
The Secretary reserves the right to require additional monitoring of the system, in
.accordance with Condition A(7) of this permit, should operation of the system fail to meet the requirements of Conditions D(1) and D(5).
Entergy Nuclear Vermont Yankee, LLC Discharge Permit ID-9-0036 Page 15 SECTION F - "COMPLIANCE REVIEW" If the results of monitoring the effluent and groundwater (Section E) show there is a possibility that the aquatic permitting criteria of the Indirect Discharge Rules may be exceeded at the designated stream flow conditions, the Secretary may increase the frequency of, or change the location of monitoring of the ground and surface water. If continued monitoring and analysis indicates that a violation of the effluent disposal rate, or a violation of the Vermont Water Quality Standards, or a significant alteration of the aquatic biota has occurred, is occurring, or is likely to occur the Secretary may require the permittee to take appropriate corrective actions to eliminate or reduce the possibility of a violation.
