Box 5030 Monroe, North Carolina August 9, 1990 Affairs Plant 28110-0531 Subject: Stream Flow Measurement Plan Teledyne Allvac - Monroe Plant NPDES Permit No. NC0045993 Union County Dear Mr. Horne, I have attached the response (August 2, 1990) from Mr. Curtis Gunter of the U.S. Geological Survey concerning review of your proposed stream flow study plan. Apparently, the correlation procedure is not appropriate for the site on Richardson Creek due to unnatural conditions (i.e. leakage from the dam). After conferring with Mr. Gunter, he relayed an alternative to the correlation procedure. A comparison method could be used in determining the low flow at the specified location on Richardson Creek. An index site (02146900 - Twelve Mile Creek at Waxhaw) nearby may be used to compare the flows. The index site must be at 7Q10 levels, at the same time measurements are taken at the site on Richardson Creek. If you have any further questions, please contact me at (919)733-5083, ext. 519.

This site is located downstream of Lake Lee and, as is stated in the report, the flow is derived from ground water and leakage from Lake Lee. Flow measurements will be made by a pygmy current meter in 11 circular culverts. The results of at least 5 flow measurements made during base -flow periods will be used to correlate with flows at Twelve Mile Creek at Waxhaw (02146900) to estimate 7Q10 for Richardson Creek. One concern with this plan is that the usual correlation procedure with nearby index stations is inappropriate for the site on Richardson Creek. The reservoir upstream from the site has an unknown effect on the natural flow of the stream, and leakage from that reservoir artificially augments the flow. The photographs submitted with the report show the 11 culverts from which flow measurements will be made. The stream appears to be pooled upstream and downstream, creating slow velocity conditions. Current meters are not recommended by the U.S. Geological Survey for use when velocities are less than 0.2 foot per second, and pygmy meters should be used only when depths are less than 1.5 feet. The method used to determine the cross - sectional area of the pipes is acceptable; however, the method to determine the average velocity in each pipe is not stated. One point velocity in each pipe would not be recommended. Please contact me if you have any questions. HCG(keh) Sincerely, H.

The plan has met the requirements for review except for including a map showing the location of the site where the flow will be measured. DEM along with the U.S. Geological Survey (USGS) will review the proposed methodology for its acceptability. Please submit a map with the location of the site to be measured so that DEM and the USGS may complete the review of the plan. Sincerely/,'\ J1. +Trevor Clements, Asst.

Box 2857 Raleigh, North Carolina 27609 July 30, 1990 Subject: Proposed Plan for Predicting Stream Flow Measurement Dear Mr. Gunther, Teledyne Allvac has submitted a proposed plan for stream flow measurement (attached) on Richardson Creek in Monroe County. We would appreciate your speedy review of this plan since flows are now low and it would be good to have Teledyne Allvac start the flow measurements as soon as possible. DEM has sent a letter to Teledyne Allvac acknowledging receipt of this plan and requesting a map with the site location sent to us. Thank you for your quick attention on this matter.

Raleigh, North Carolina 27611-7687 Telephone 919-733-7015 TELEDYNE ALLVAC PROPOSED PLAN FOR DEVELOPING PARTIAL FLOW RECORD IN RICHARDSON CREEK (Union County) Prepared by: an Horne, P. ager of Environmental Affairs ledyne Allvac Purpose: The purpose of this study is to develop a reliable estimate of flow conditions in Richardson Creek. This information is required pur— suant to Part III, E. of NPDES permit No. NC0045993. It is intended to provide site specific flow estimates for the waters receiving the discharge from Teledyne Allvac — Monroe plant. Description of Proposed Methodology: A field assessment was made which involved wading Richardson Creek down— stream and upstream of the discharge point. Pictures are included in Appendix 'A' for the purpose of providing a general description of stream conditions. The stream is fairly broad (approximately 30-50 feet), shallow and has a rocky bottom. Water flows very slowly in the wider, deeper sections but increases velocity in a few, scattered narrow/shallow areas. Upstream flow is derived from groundwater seepage, storm runoff and nor— mal leakage from an impoundment (Lake Lee) located approximately lz miles upstream. Conditions in the stream are such that the most practical location for reliable flow measurement appears to be at a point in the creek approximately one mile above the discharge. At this point there is an existing bridge which serves as a passage for golf carts that is built over eleven (11), 48" diame— ter concrete culverts installed in parallel (see Appendix 'B' for pictures of this bridge and culverts). The construction is such that all stream flow must pass thru the culverts. Flow measurement will be made by using a Pygmy current flow meter to measure the velocity of flow thru each culvert. The depth of water flowing thru each culvert will be measured to ascertain the cross sectional area of flow. The recorded flow will be the product of velocity multiplied times cross sectional (wetted) area. Procedures for Flow Measurement: Measurements will be made weekly beginning thirty (30) days after receiv— ing approval and will continue for a minimum of twelve (12) weeks or longer until at least five (5) measurements are obtained during "base flow" conditions. Base flow will be considered to occur after five (5) days of the most recent rainfall event (rainfall greater than 0.1 inch in 24 hours). Rainfall will be measured and recorded daily during the period of flow measurement. Measurements of flow velocity will be made at the outlets of each of the eleven (11) culverts using a Pygmy current meter as described in Appendix 'C'. The depth of flow thru each culvert will be measured with a tape or ruler. Using the measured depth of flow and the known culvert diameter (48") the wet— ted cross sectional area will be determined. The flow of the stream will be the sum of flows computed for each of the eleven (11) culverts as computed by multiplying velocity times wetted cross sectional area. The twelve (12) week period of measurement is a minimum and will be extended as necessary until at least five (5) measurements are obtained under base flow conditions. Recorded measurements will be correlated to measurements recorded at the same time at USGS continuous station No. 02146900 on Twelve Mile Creek near Waxhaw in Union County. A request has been made with USGS to provide print— outs of their flow recordings at this station during the period of flow measurement. The results of our flow measurements will be plotted versus the measure— ments at the USGS station to develop a correlation curve as depicted in DEM's "Procedures For Projecting A Seven —Day Ten —Year Low Value At An Ungaged Site". From the correlation curve, the estimated 7Q10 for Richardson Creek will be extrapolated. Upon completing the flow measurements, a report will be forwarded to DEM which summarizes the measurements dates and times of measurements, rainfall measurements, calculated flows, USGS flow correlation data, projected correlation curve and projected 7Q10 flow. The report will contain the above information plus details and descriptions as appropriate to describe encoun— tered conditions, etc. to substantiate the validity of the measurements made.

It is not adapted for cable suspension. _ The construction is similar to.the standard No. 622 . model, except for the smaller size and the use of a single contact, indicating only each revolution. The bucket wheel of the Pygmy Current 'Meter is 2 inches in dia- meter, as compared with the 5 . inch wheel of No. 622. The other dimensions are in about the same proportion. The Pygmy Current Meter .is extremely sensitive to low velocities, and starts indicating at 0.05 ft./sec. The velocity in feet per second equals the revolutions of the bucket wheel per second for all practical purposes. Basic Meter: No. 625, consisting of frame; removable pivot with set screw and keeper screw; lower bearing; shaft; bucket wheel; contact chamber. Spare Parts: One extra pivot with adjusting nut and lock screw; shipping pivot (used when meter is ship- ped). All in mahogany meter case.
