Dear Mr. Hartwell: DEPARTMENT OF THE ARMY US ARMY CORPS OF ENGINEERS NEW ENGLAND DISTRICT 696 VIRGINIA ROAD CONCORD MA 01742-2751 October 10, 2018 • This letter concerns the U.S. Army Corps of.Engineers individual permit review of your proposal for a 1 o·-yeai Dredge Material Management Plan for Paradise Pond on the Mill River in . . ·Northampton, Massachusetts. As part of this Dredge Material Management Plan, you have requested authorization to dewater the 9 .4 acre Paradise Pond one+ times a year; to mechanically . . . redistribute bottom sediments into areas ·where they can be more easily transported (sluiced) do~iver; and to.open the Paradise Pond Dam low-flow outlet during periods of high flow (over 200 cfs) in order to promote the downriver .sluicing of accumulated bottom sediments. The goal of this Dredged Material Management Plan is to maintain at least a·2-foot minimum normal pool depth throughout Paradise Pond to support existing recreational and academic uses. The Corps advertised this project via a public notice. comment period between August 7, and September 7, 2018.

The DPW has appreciated being included in the planning and development process for the sediment management,project and is generally in support of the proposed project as "·,: documented in the Individual Per1nit Application. The following comments are intended t.o provide input for the USACE Individual Section 404 Permit conditions. A public hearing is not being requested. The ''Mill River ·~B, Mill River Diversion, .Smith College Dike ·-Northampton, MA'' Flood D·amage Reduction Segment begins as an earthen dike ·downstream of the Paradise Pond Dam and extends southward along the east bank of Mill River about 1, 100 feet to West Street. A Diversion Canal is used to divert the Mill River, which begins around Hebert Avenue and extends to South Street approximately 3,000 feet in length, where a 19.5 foot high Drop Structure (concrete spillway) is located for channel grade control. The Mill River then flows from the Drop Structure, approximately 1.5 miles to the Oxbow · on the Connecticut River. Based on the 1939 flood control system design plans and the 1978 FEMA Flood Insurance Study, the slope of the Mill River between Paradise Pond Dam and West Street is approximately 0.24o/o. Between West Street and the Drop Structure the ~lope decreases significantly to approximately 0.14%, thus significantly decreasing sedime11t mobility in that Segµlent. . The DPW's concerns with the proposed sediment sluicing project are related to potential sediment . accumulation in the flood control channel, primarily behind the Drop Structure, within the Diversion ~anal, given the clecreased slope of that segment of the Mill River. The segment of.the channel downstream of the Drop Spucture to the Oxbow Bridge is not of primary concern to the DPW related to ' . sediment ·accumulation since it receives backwater from the Connecticut River and the channel capacity is adequate. Sediment ?-Ccumulation has the potential to redu.ce flood flow capacity by reducing the cross- sectional area of the channel and/or creating sediment islands within the channel on which vegetation · could e$tablish. As the Federal Sponsor, the City of Northampton is ultimately. responsible for the . ongoing .maintenance and operation of the flood control system. , .

August 16, 2018 Paul Sneeringer The DPW requests the following to occur prior to the issuance of an Individual Pennit to give th·e DPW an opportunity to evaluate the predicted impacts to the downstream channel: • • A REC-RAS sediment transport model shall be developed and results shall be provided to the City. The inodel should by run witl1 seve~al sluicing alternatives to ~valuate the effects of a range of potential sto11n scenarios and sensitivity analyses using various grain size distributions from the pond sediment. The HEC-RAS model area shall extend from Paradise P9nd Dam to the :Prop Structure. At a minimum, scenarios should include an example 1-year frequency storm and a 10- year design sto11n. Ideally, severaJ months of historical flow data during typical storm events would provide information on anticipated sediment movement through the segment. Initial model conditions should consist of the permitted annual sedini~nt .release volume in the plunge pool. The model results sl1ould depict longitudinal sediment profiles and volumetric analysis of sediment discharged over the Drop Structure an·d r~t<:l:ined in · the system upstream of the Drop Structure. The DPW requests the following provisions be included in the Individual Permit approval to provide a mechanism for the DPW's involvement in the Paradise Pond sediment management project, and require Smith College to perfor1n remedial action in the case of unwanted sediment accumulation in. the Mill River channel downstream of Paradise Pond Dam that .negatively impacts the capacity, functionality, or maintenance of the flood control system: • • Annual cross-section monitoring at Sites 1 and 2 as identified in the ''Paradise Pond Sediment Monitoring Project 2017 Report." The City requests an additional monitoring station be added in between Site 1 and Site 2 to monitor mid-reach sediment ·~ccumulation. The annual report provided to the DPW should include cross-sectional figures depicting sediment depths and volumetric sediment accumulation estimates within the Diversion Canal, to be reported in cumulative totals since the commencement of sluicing operations under the USACE Individual Permit. · • A conditional requirement for Smith College to fund, pe11nit, and otherwise be responsible for dredging or maintaining the Dive~sion Canal should sediment releases from Paradise Pond result in unacceptable sediment accumulation within the channel. The threshold for unacceptable sediment accumulation shall be if greater than 50% of any cross-sectional area below the Ordinary High· Water Mark contains sediment compared to baseline conditions (pre- authorization under the Individual Permit). Remedial action shall be implemented if the above- mentioned sediment accumulation condition is persist~nt over a 2 year monitoring period. ,.

However, based on the. location I don't think·we'll need to offer EFH con·servation recommendations . • Mike I On Thu, Sep 6, 2018 at 4:44 PM Sneeringer, Paul J CIV USARMY CENAE (US) <Paul.J.Sneeringer@usace.army.mil <ma ilto: Pa ul.J .Sneeringer@usace.army.m ii> <ma ilto: Pa ul.J .Sneeringer@usace.a rmy.m ii <mailto:Paul.J.Sneeringer@usac·e.army.mil> > > wro.te: . Alison and Mike: . I am current.ly reviewing a proposal from Smith College for a 10-year Sediment Management Program for Paradise Pond on the Mill River in Northampton, Massachusetts. Under this Sediment Management Program, Smith . . College would be authorized to regrade areas of Paradise Pond; to mechanically redistribute bottom sediments within • the pond and the existing plunge pool (downriver of the Paradise Pond Dam); and to utilize the existing low-flow outfall during periods of: high flow in order to promote the downriver transportation (sluicing) of a·ccumulated bottom sediments from the pond. The goal o.f this pr~gram is to maintain a 2-foot minimum normal pool depth throughout Paradise Pond in order to support existing recreational and acaderl}ic uses. Using t -his Sediment Management Program, . . Smith College .hopes to be able to sluice an additional 1,500 to 3,000 cubic yards of bottom sediments downriver per year. The Mill River is a tributary of the Conn~.cti~ut River. Do~nriver of the Paradise Pond Dam, th~ Corps constructed the Mill River Diversion Channel to· divert the mouth of the Mill River away from downtown Northampton and instead to outfall into the. Oxbow. The downstream end of the Mill River Diversion Channel includes an 8-10 foot ·dam/drop structure (under the Route 10 Bridge). This dam restricts upriver fish migration from the Connecticut Riyer. The Mill River Diversion Channel dam is located approximately 0.9 miles downriver of the Paradise Pond Dam. The Mill . . River enters the Oxbow approximately 2.4 miles ·downriver of the Paradise Pond pam. I am having diffi·culty figuring out how to best c,lassify ·this non-tidal sediment sluicing project under the April 201-7 Essential Fish Habitat (EFH) Programmatic Consultation Process. Is it best classified as a repair and maintenance project (General Permit #1), dredging and disposal· project (General Permit #5), a recreational facility project (General Permit #8), an environmental restoration project (General Permit #23), or none of the above. I am . . trying to figure out if this project is eligible for programmatic or individual EFH consultation. This project does not . . involve impacts to· tidal submerged vegetatiof1, tidal special aquatic sites, or intertidal areas. As stated above, ~his . . project should not impact anadromous fish migrations. On the other hand, do I need to consider impacts to non-tidal natural rocky ~abitats or existing fre.shwater mussel beds within the Mill River? . Beyond this, I am not sure how to apply appropriate erosion control and sedimentation requirements . . to a sediment slicing project. The primary purpose for the sediment management program is to promote the sluicing of additional bottom sediment from Paradise Pond. The approximate 1,~00 to 3,000 cubic yards of bottom sediments that • 2 I Smith College hopes to sluice each year is only a fraction of the tota.1 sediment that is transported over the dam each . year. My initial thought is that Smith College 1s Paradise Pond Sediment Management Plan will have limited impacts on EFH species within the Connecticut River and downriver sections of the Mill River.

Thank you for the update on the status of your :rvIBSA review of the Paradise Pond Sediment Management Protocol. ·In response to your request for additional information we offer the following, in Comment:Respo.nse form'\t. Comment: As we are now more than five years from the 2013 submission of a filing fee, the :rvIBSA . Application is incomplete until we receive a ·filing fee for the revised project. For us to issue a formal determination; we will need to receive a filing fee based upon the average of the work area.

As this is typ~cally the highest water levels in a given year, does the .outlet have the capacity to actually maintain a consistent Yi pool depth given th~ watershed inputs during this time of year? If not, would a pump be used to maintain the drawdown condition? . . Response: Flow rates in the Mill River vary widely throughout the year. Smith would only start a drawdown for mechanical redistribution when flows are below average (approximately 100 cubic · . . feet per second ( cfs )). Pumps, siphons, or any other means of bypass other than the lpw level outlet are not proposed. 8 BLACKSTONE VALLEY PLACE LINCOLN , RI 02865 T 401.334.4100 F 401 .334 .4108 10 LINCOLN ROAD, SUITE 210 FOXBORO, MA 02035 T 508 .543.1755 F 508.543.1881 " • . . . . .. • •• NHESP -2 -September 26, 2018 Comment: What are the consequences to the project and work ifthe work-area is inundated during · the drawdown? What measures will be implemented to address these?. Response: There are no adverse consequences to the project . if the Pond fills . during a partjal drawdown, other than a ·brief delay in the work. The only equipment in the Pond will be a bulldozer, which will be parked out of the Pond when not in use (i ~e.~ 01:1tside of working hours). If a significant rainfall is expected, work will be suspended and the equipment remo~ed from the Pond until river flows recede to a level that would allow drawdown to recommence (well below 200 cfs). Please note that it does take many hours for a significant rainfall to alter flows through the Pond. As an example, Smith recently experienced a 3" rainfall which started just before midnight ·on I 9/17/2018 an4 ended ·before noon on 9/18 /2018. Flow was at 60 cfs at the beginning of the rain event. Peak flow was appro~ately 2200 cfs .at 12:15 PM on Tue 9/18 and had receded to be.low 200 cfs by approximately 1 :00 AM, on 9/20/18. Similarly, Mill River flow on the morning of 9 /25/2018 was at 90 cfs. :By approximately 4:30 that day Smith had received 1.54" of rain. The. USGS station reported 180+ cfs flow at 2: 15 PM, 344 · cfs at 3: 15 PM, and 805 cfs at 4: 15 PM. . . These examples demonstrate that flows do incre~e quickly once they begin to rise but that there is a significant delay before that happens, which would allow equipment to be removed from the pond. S~ith conclu~es that mechanical relocation of sediment can be suspended without adverse consequences in the e~ent of unanticipated storm events. Comment: In the NOI and MEPA filing in the Revised Sediment Management Protocol (page 3, . . number 4), t~e filing has the following statement ''Large storms resulting in rapid sedim ent accumulation may require interim drawdown/redistribution events.'' Can you please explain what this means? Is this meant to say that the project many need I /year re-distribution or that it could · occur more than 1/year? Does this mean to suggest there could be redistribution events outside of the proposed time of year (October through May). Response: This is a recognition that infrequent, inordinately large storm events have the potential to deposit large amounts of new sediment in those areas most susceptible to deposition. Ifth~s ~ere to o ccur shortly after a redistributio~ project, Smith would like to have the latitude to address the accumulation without waiting until the next year, provided that the work can be done within the • proposed time of year. Smith ~oes not intend to routinely conduct more than 1 sediment re- dis~ribution project in any given year and hopes to go several years between redistribution projects. Smith also recognizes, however, that regularly scheduled redistribution efforts will reduce the amount of work and potential impacts per project and therefore proposes a yearly redistribution program. Comment: Will any machinery entering the river/pond be required to change hydrauli.c fluids to • biodegradable ones? If not, please explain why this is n:ot possible. Respo~se: Smith will require that all machinery working in the Pond use biodegradable hydraulic fluids and would accept this a condition of approval . • • ' NHESP ·-3-September 26, 2018 Comment: From a larger watershed perspective, the project is proposing a (potentially) annual drawdown of Paradise Pond. While not intended for vegetation management, the result to the watershed is the same. ·For drawdowns, the reference used by ConComms is usually the GEIR for Lake and Pond Management ( G.EIR: https :/ /www.mass.gov/files / docmnents/20 l 6/08/p1n/main-. geir.pdf). These criteria were developed to guide projects such as this to avoid impacts to fish and wildlife resources. I was unable to find a specific mention of these criteria or a discussion of how the project can meets the relevant WPA performance standards without meeting these criteria. Below are the key dates described in the GEIR. · ' . • Commence draw down after the beginning of November. • Achieve the target draw down depth by the beginning of De·cember. • Achieve full lal(e level by the beginning o.f April. • Keep outflow during drawdown below a discharge equivalent to 4 cfs per square mile of watershed. Once the target water level is achieved, match outflow to inflow to the greatest extent possible, m~taining a stable water level. • Keep outflow during refill above a discharge equivalent to 0.5 cfs per square mile of watershed. Can this project be designed to meet these criteria? If not, please provide infor:1J1ation as to how the project will meet ·the WPA Performanc.e Standards underlying these criteria. The No1ihampton Conservation Commission should review this during their hearings on this case. and our Fisheries staff can provide additional guidance to them upon request. Response: • • • • • f Smith will commit to commencing draw downs after the beginning of November . Drawdown depth can typically be achieved within 24 holll·s from commencement of drawdown and therefore the drawdowns will be complete before the beginning of December. Depending on flows, full pool could be reestablished within 2 weeks of initial draw down. With more rainfall (on average) in late fall, this is a very likely scenario. Therefore, full pond will be achieved by the beginning of April. . . . Per StreamStats, the Mill River watershed contributing to Paradise Pond is approximately 54 square miles in size and therefore 4 cfs per square mile (cfs/sm) of . watershed is slightly greate14 ·than the 200 cfs maximwn capacity of the low water outlet .. Pond drawdown is not possible if the incoming flow is greater than 200 cfs and therefore this ~riterion will be met. ·once the target water level is achieved the sluice • gate can be operated to match incoming flows, ·maintaining a staple water level at a desired depth. Smith has many years of expe·rience operating the sluice gate in exactly this fashion and proposes to do so during all mechanical redistribution projects. A discharge equivalent to 0.5 cfs /sm of watershed equates to 27.5 cfs.,.which is the threshold to which Stnith has been held in the past. As part of Smith's recent Notice of Intent ( 4/27/2018) and Order of Conditions (8 /712018) for Water Resources Maintenance Activities (DEP File No. 246-0715) this threshold·for minimum flow during refill ha~ been reduced to 13.8 cfs or 0.25 cfs/sm with fill rate restrictions of 0.5 • ' • • ... • • , • NHESP -4-September 26, 2018 . vertical ft/hour between 5/15 & 6/15 and 2.07 vertical ft/hour from 6/15 to 9/1. .

In summary, Smith can meet the above criteria, allowing for the adjustment in minimum downstream flows during refill. Thank you for the opportunity to provide the above information.

Species Act (50 CFR 17.11), which is administered by the United Sta~es Fish & Wildlife Service (USFWS). Over the last several years, the Proponents have conducted a series of experimental impoundment releases to develop an adaptive management plan for Paradise Pond. The goal was to determine if using MASSWILDLIFE .· NHESP No. 10-27790, NPC Paradise Pond, page 2 of 2 , the low-level outlet to relea se impounded sed iments during higher flow events would both maintain . • sufficient depth for the College's recreation and education needs (a minimum water depth of 3 feet below the spillway elevation) while not harm · (and hopefully improve) downstream habitats. Post .management monitoring results found that only using the low-level outlet would not mobilize sufficient sediment from · the impoundment to be self-sustaining. to meet ttie recreational goals. The Proponents have therefore . . . . modified the adaptive management plan to include the use of a conventional drawdown to . allow for mechanical redistribution of sediments into the "active" channel · of the imp·oundment, which is located • . . . around the north end of the impoundment. The. riverine sediments moved into the "active" channel will them be mobilized out of the low-level outlet during natural high-flow events. The project would conduct a drawdown to facilitate the mechanical re-distribution of the sedif!1ent, which may occur an.nually. The Proponents have also reduced the target water depth to 2 .feet from the initial 3 feet. Tbe results of the past studies suggest that a balance in the interests can be found, with some potential benefits to the 9verall River habitat below the Smith College Dam. Based on the data collected to date by the Prqponents1 . we anticipate requiring conditions as to the timing and frequency of the drawdown, li.mits to the amount of suspended sediments during high-flow event to avoid smothering downstream mussels, and ongoing monitoring. We are confident that outstanding details can be resolved during the MESA review process. We will continue to consult with the Proponent during the MESA review process to develop conditions to avoid .impacts to state-listed species . . . . The Division yvill not render a final decision regarding the MESA until the MEPA review process and its . associated public comment period is complete, and until all required application· materials have been submitted to the Division. As the MESA review process has not formally initiated, no alteration to the soil, surface, or vegetation associated with the Project shall occur until the Division has made a final decision pursuant to 321CMR10.14 ·and .321CMR10.18.
