The pump station is required to convey flows to nearby gravity sewers, which will then convey flows to the existing Phinney’s Lane Pump Station and on to the Water Pollution Control Facility for treatment. The construction of this pump station and sewer expansion project will help relieve the Town’s wastewater issues by: 1) removing significant nitrogen loads from coastal embayments, 2) providing protection for drinking water wells, ponds and lakes, and 3) enhancing economic development. To reach the proposed pump station site from 230 South Street, Hyannis MA 02601, start heading west along Main Street for approximately 0.75 miles towards the rotary. Take the second exit onto West Main Street and travel 2 miles northwesterly towards Falmouth Road (Route 28). Take a left onto Route 28 West and travel approximately 2.5 miles to the intersection with Old East Osterville Road. Take a left onto Old East Osterville Road and travel 0.3 miles south towards the intersection with Oldham Road. Travel southwesterly for approximately 660 feet and the project site will be on your left, just after #191 Oldham Road. Environmental Considerations The proposed project will include work within the 100-foot buffer zone of an isolated wetland. Work within the 100-foot buffer zone will include impacts associated with the construction of the proposed pump station and installation of new sewer mains will occur within the 100-foot wetland buffer zone on Oldham Road and the Town owned parcel located at #181 Oldham Road. The new sewer mains will be installed within the existing roadways along their entire length. Therefore, any impacts will occur only within previously altered roadways. This Notice of Intent (NOI) will focus on the proposed pump station site impacts as the installation of the new sewer mains will occur within the existing paved roadways. Additional explanation of these impacts are provided below: Wetlands Protection Act Exemptions New sewer main installation is proposed within the 100-foot wetlands buffer zone. Work within 100-foot Wetland Buffer Zone: 310 CMR 10.02(2)(b) Activities within the Buffer Zone: Any activity other than minor activities identified in 310 CMR 10.02(2)(b)2 proposed or undertaken within 100 feet of an area specified in 310 CMR 10.02(1)(a) which, in the judgment of the issuing authority, will alter an Area Subject to Protection under MGL c 131, ss 40 is subject to regulation under MGL c 131, ss 40 and requires the filing of a Notice of Intent. The areas subject to jurisdiction identified in 310 CMR 10.02(1) (b) through (f) do not have a buffer zone. This is a limited project on the Town owned parcel. This project will have no direct impacts to the wetland resource and will be located within the 100-foot buffer zone, but care will be taken to avoid impact to the 50-foot buffer zone. Work within the 100-foot buffer zone is unavoidable due to the dimension of the lot and that the pump station cannot be sited somewhere else along Oldham Road as this is the only Town owned property on this street. Resource Area Impacts/Mitigation Measures The work to be performed under this NOI includes 4,800 square feet of work within the 100-foot buffer zone (but outside the 50-foot no disturbance area) in conjunction with the construction of a wastewater pumping station located on the Town owned parcel at #181 Oldham Road. Prior to any work activities on site, straw wattles/compost socks will be installed around the perimeter of the site and appropriate catch basin protection will be provided as shown on the attached plans (see Appendix F). During site work, care will be taken to minimize off-site migration of sediment and pollutants to the wetlands resource areas. These resource areas were delineated on April 13th, 2023 by Weston & Sampson personnel trained in the U.S. Army Corp of Engineers Wetland Delineation Manual. The delineation memo can be found in Appendix D. The Contractor shall not store waste materials and stock piles within 100-feet of any wetland unless shown on the plans and approved by the Barnstable Conservation Commission. Furthermore, the Contractor shall store waste materials in stockpiles on opposite sides of the trench from the wetlands whenever possible. Best management practices will be used during construction to avoid off site impacts associated with the project. Temporary straw wattles/compost socks shall be utilized to help prevent siltation in wetland areas. Trench dewatering shall be performed in accordance with Specification Section 02240 (included herein as part of Appendix G). All trenches shall be dewatered through proper siltation control measures as indicated on the construction drawings included in Appendix F. In accordance with the Town of Barnstable Conservation Commission Regulations Chapter 704-3(B), a 50-foot buffer zone exists prior to any proposed work and is proposed to remain intact. Therefore, proposed work within the 50 to 100 foot buffer zone shall not require further buffer zone enhancement. \\wse03.local\WSE\Projects\MA\Barnstable MA\221360 Route 28 West Sewer Expansion Design\Permits\Conservation Commission\Appendix B Project Description.doc Town of Barnstable, MA DEPARTMENT OF PUBLIC WORKS NOTICE OF INTENT APPENDIX C Abutter Notifications 1,200.00 Conservation Notice of Intent (NOI) Abutter Map for Subject Parcel This map is for illustration purposes only.

Dewatering includes lowering the water table and intercepting seepage which would otherwise emerge from the slopes or bottom of the excavation; increasing the stability of excavated slopes; preventing loss of material from beneath the slopes or bottom of t he excavation; reducing lateral loads on sheeting and bracing; improving the excavation and hauling characteristics of sandy soil; preventing rupture or heaving of the bottom of any excavation; and disposing of pumped water. B. Normal dewatering is defined as using conventional pumps installed in open excavations, ditches, or sumps. Special dewatering is defined as using single or two stage wellpoints, deep wells, or eductor and ejector systems installed in drilled holes or jetted in place. 1.04 QUALITY ASSURANCE: A. The Contractor is responsible for the adequacy of the dewatering systems. It shall retain the services of a Professional Engineer registered in the state where the project is located, experienced in dewatering systems, to independently evaluate the boring logs and any other soils information available to determine those areas that will require special dewatering techniques and to design the required system. The Contractor's Professional Engineer shall provide sufficient on-site inspection and supervision to assure that the dewatering is carried out in accordance with its design. 08/20/2024 02240-2 B. The dewatering systems shall be capable of effectively reducing the hydrostatic pressure and lowering the groundwater levels to a minimum of 2 feet below excavation bottom, unless otherwise required by the Engineer, so that all excavation bottoms are firm and dry. C. The dewatering system shall be capable of maintaining a dry and stable subgrade until the structures, pipes and appurtenances to be built therein have been completed to the extent that they will not be floated or otherwise damaged. D. The dewatering system and excavation support (see Section 02252) shall be designed so that lowering of the groundwater level within the work area does not adversely affect structures, utilities or wells outside of the work area. E. Where special dewatering is used, the Contractor shall obtain at its expense the services of a registered professional engineer to investigate, design and monitor the dewatering system. The Contractor shall also furnish materials and install at least two observation wells at each excavation area.

The Contractor shall perform all work of any nature and description required to accomplish the work as shown on the Drawings and as specified. 2. Excavations, unless otherwise required by the Engineer, shall be carried only to the depths and limits shown on the Drawings. If unauthorized excavation is carried out below required subgrade and/or beyond minimum lateral limits shown on Drawings, it shall be backfilled with gravel borrow and compacted at the Contractor's expense as specified below, except as otherwise indicated. Excavations shall be kept in dry and good conditions at all times, and all voids shall be filled to the satisfaction of the Engineer. 3. In all excavation areas, the Contractor shall strip the surficial topsoil layer and underlying subsoil layer separate from underlying soils. In paved areas, the Contractor shall first cut pavement as specified in paragraph 3.02 B.1 of this specification, strip pavement and pavement subbase separately from underlying soils. All excavated materials shall be stockpiled separately from each other within the limits of work. 4. The Contractor shall follow a construction procedure, which permits visual identification of stable natural ground. Where groundwater is encountered, the size of the open excavation shall be limited to that which can be handled by the Contractor's chosen method of dewatering, and which will allow visual observation of the bottom and backfill in the dry. 5. The Contractor shall excavate unsuitable materials to stable natural ground where encountered at proposed excavation subgrade, as required by the Engineer. Unsuitable material includes topsoil, loam, peat, other organic materials, snow, ice, and trash. Unless specified elsewhere or otherwise required by the Engineer, areas where unsuitable materials have been excavated to stable ground shall be backfilled 08/23/2024 02300-8 with compacted special bedding materials or crushed stone wrapped all around in non-woven filter fabric. B. TRENCHES: 1. Prior to excavation, trenches in pavement shall have the traveled way surface cut in a straight line by a concrete saw or equivalent method, to the full depth of pavement. Excavation shall only be between these cuts. Excavation support shall be provided as required to avoid undermining of pavement. Cutting operations shall not be done by ripping equipment. 2. The Contractor shall satisfy all dewatering requirements specified in Section 02240 DEWATERING, before performing trench excavations. 3. Trenches shall be excavated to such depths as will permit the pipe to be laid at the elevations, slopes, and depths of cover indicated on the Drawings. Trench widths shall be as shown on the Drawings or as specified. 4. Where pipe is to be laid in bedding material, the trench may be excavated by machinery to, or just below, the designated subgrade provided that the material remaining in the bottom of the trench is not disturbed. 5. If pipe is to be laid in embankments or other recently filled areas, the fill material shall first be placed to a height of at least 12-inches above the top of the pipe before excavation. 6. Pipe trenches shall be made as narrow as practicable and shall not be widened by scraping or loosening materials from the sides. Every effort shall be made to keep the sides of the trenches firm and undisturbed until backfilling has been completed. 7. If, in the opinion of the Engineer, the subgrade, during trench excavation, has been disturbed as a result of rain, surface water runoff or groundwater seepage pressures, the Contractor shall remove such disturbed subgrade to a minimum of 12 inches and replace with crushed stone wrapped in filter fabric. The cost of removal and replacement shall be borne by the Contractor. 8. The Contractor shall obtain a trench permit from the municipality where the trench is located prior to making any excavations of trenches (any subsurface excavation greater than three (3) feet in depth and fifteen (15) feet or less between soil walls as measured from the bottom). 9. All trenches required to be permitted must be attended, covered, barricaded, or backfilled. Covers must be road plates at least ¾-inch thick or equivalent, barricades must be fences at least 6-feet high with no openings greater than 4-inches between vertical supports and all horizontal supports required to be located on the trench-side of the fencing. C. BUILDING AND FOUNDATION EXCAVATION: 08/23/2024 02300-9 1. Excavations shall not be wider than required to set, brace, and remove forms for concrete, or perform other necessary work. 2. After the excavation has been made, and before forms are set for footings, mats, slabs, or other structures, and before reinforcing is placed, all loose or disturbed material shall be removed from the subgrade. The bearing surface shall then be compacted to meet the requirements of this specification. 3. If, in the opinion of the Engineer, the existing material at subgrade elevation is unsuitable for structural support, the Contractor shall excavate and dispose of the unsuitable material to the required width and depth as required by the Engineer. If, in the opinion of the Engineer, filter fabric is required; the Contractor shall place filter fabric, approved by the Engineer, as per manufacturer’s recommendations. Crushed stone shall then be placed in lifts and compacted to required densities. Backfill shall be placed to the bottom of the proposed excavation. D. EXCAVATION NEAR EXISTING STRUCTURES: 1. Attention is directed to the fact that there are pipes, manholes, drains, and other utilities in certain locations. An attempt has been made to locate all utilities on the drawings, but the completeness or accuracy of the given information is not guaranteed. 2. As the excavation approaches pipes, conduits, or other underground structures, digging by machinery shall be discontinued and excavation shall be done by means of hand tools, as required. Such manual excavation, when incidental to normal excavation, shall be included in the work to be done under items involving normal excavation. 3. Where determination of the exact location of a pipe or other underground structure is necessary for properly performing the work, the Contractor shall excavate test pits to determine the locations. 3.03 BACKFILL PLACEMENT AND COMPACTION: A. GENERAL: 1. Prior to backfilling, the Contractor shall compact the exposed subgrade to a firm and unyielding condition with at least 4 passes of fully loaded, ten cubic yard dump truck over the subgrade or other acceptable compaction equipment subject to the approval of the Engineer. 2. After approval of subgrade by the Engineer, the Contractor shall backfill areas to required contours and elevations with specified materials. 3. The Contractor shall place and compact materials to the specified density in continuous horizontal layers, not to exceed nine (9) inches in uncompacted lifts. 08/23/2024 02300-10 The degree of compaction shall be based on maximum dry density as determined by ASTM Test D1557, Method C. The minimum degree of compaction for fill placed shall be as follows: Percent of Location Maximum Density Below pipe centerline 95 Above pipe centerline 92 Below pavement (upper 3 ft.) 95 Embankments 95 Below pipe in embankments 95 Adjacent to structures 92 Below structures 95 4. The Engineer reserves the right to test backfill for conformance to the specifications and the Contractor shall assist as required to obtain the information. Compaction testing will be performed by the Engineer or by an inspection laboratory designated by the Engineer, engaged and paid for by the Owner. If test results indicate work does not conform to specification requirements, the Contractor shall remove or correct the defective Work by recompacting where appropriate or replacing as necessary and approved by the Engineer, to bring the work into compliance, at no additional cost to the Owner. All backfilled materials under structures and buildings shall be field tested for compliance with the requirements of this specification. Note to Specifier: Determine whether the above testing for structural subgrade shall be paid for by Owner or Contractor. 5. Where horizontal layers meet a rising slope, the Contractor shall key each layer by benching into the slope. 6. If the material removed from the excavation is suitable for backfill with the exception that it contains stones larger than permitted, the Contractor has the option to remove the oversized stones and use the material for backfill or to provide replacement backfill at no additional cost to the Owner. 7. The Contractor shall remove loam and topsoil, loose vegetation, stumps, large roots, etc., from areas upon which embankments will be built or areas where material will be placed for grading. The subgrade shall be shaped as indicated on the Drawings and shall be prepared by forking, furrowing, or plowing so that the first layer of the fill material placed on the subgrade will be well bonded to the subgrade. 8. Where called for on the Drawings, Lightweight Fill shall be placed and compacted as recommended by the manufacturer. The exact number of passes shall be approved by the Engineer to insure stability of the layer. As soon as the compaction of each layer has been completed, the next layer shall then be placed. The Contractor shall take all necessary precautions during construction activities in 08/23/2024 02300-11 operations on or adjacent to the Lightweight Fill to ensure that the material is not over-compacted. Construction equipment, other than for compaction, shall not operate on the exposed Lightweight Fill. The top surface of the Lightweight Fill lying directly below the gravel course shall be chinked by additional rolling of the Lightweight Fill to prevent infiltration of fines. (Next section should be used only if required as a result of site-specific conditions and only after review by Geotechnical Engineer) 9. In areas where noted on the Drawings, the Contractor shall surcharge the organic layers to control post construction consolidation settlement. The Contractor shall apply the surcharge loads in a manner and for a duration acceptable to the Engineer. The lateral extent of surcharge load should be as narrow as practical to provide stable slopes and within the restriction of the project permits. The surcharge load in these areas shall remain for a minimum of 6 months or as required by the Engineer. After approval by the Engineer, remove the surcharge load and grade to the proposed elevation. During surcharge loading in this location, the Contractor shall provide survey results of settlement on the top of the berm. The frequency of the survey data shall be as follows: 1 survey per day during 1st week 2 surveys per week during 2nd & 3rd week 1 survey per week for 2 months thereafter 1 survey per month for the remaining period The periodic surveys for settlement monitoring shall be taken at the same locations, not more than 100 feet apart. B. TRENCHES: 1. Bedding as detailed and specified shall be furnished and installed beneath the pipeline prior to placement of the pipeline. A minimum bedding thickness shall be maintained between the pipe and undisturbed material, as shown on the Drawings. 2. As soon as practicable after the pipes have been laid, backfilling shall be started. 3. Unless otherwise indicated on the Drawings, select backfill shall be placed by hand shovel in 6-inch thick lifts up to a minimum level of 12-inches above the top of pipe. This area of backfill is considered the zone around the pipe and shall be thoroughly compacted before the remainder of the trench is backfilled. Compaction of each lift in the zone around the pipe shall be done by use of power-driven tampers weighing at least 20 pounds or by vibratory compactors. Care shall be taken that material close to the bank, as well as in all other portions of the trench, is thoroughly compacted to densities required. 4. Class B backfill shall be placed from the top of the select backfill to the specified material at grade (loam, pavement subbase, etc.). Fill compaction shall meet the density requirements of this specification. 08/23/2024 02300-12 Note to specifier: According to the Geotechnical Group water jetting should not be used except for limited circumstances. Therefore, consult with Geotechnical Group to determine if the following paragraph should be left in the spec. 5. Water Jetting: a. Water jetting may be used when the backfill material contains less than 10 percent passing the number 200 sieve but shall be used only if approved by the Engineer. b. Contractor shall submit a detailed plan describing the procedures it intends to use for water jetting to the Engineer for approval prior to any water jetting taking place. c. Compaction of backfill placed by water jetting shall conform to the requirements of this specification. 6.

Loam shall be at least 6-inches compacted thickness. B. Lime shall be applied to bring the pH to 6.5 or, without a soil test, at the rate of 2 -3 tons of lime per acre. C. Fertilizer shall be applied according to the soil test, or without a soil test, at the rate of 1000 pounds per acre. D. Loam shall be worked a minimum of 3-inches deep, thoroughly incorporating the lime and fertilizer into the soil. The loam shall then be raked until the surface is finely pulverized and smooth and compacted with rollers, weighing not over 100 pounds per linear foot of tread, to an even surface conforming to the prescribed lines and grades. Minimum depth shall be 6-inches after completion. 3.02 SEEDING: A. Seeding shall be done when weather conditions are approved as suitable, in the periods between April l and May 30 or August l5 to October l, unless otherwise approved. B. If there is a delay in seeding, during which weeds grow or soil is washed out, the Contractor shall remove the weeds or replace the soil before sowing the seed, without 07/05/2023 02920-5 additional compensation. Immediately before seeding is begun, the soil shall be lightly raked. C. Seed shall be sown at the approved rate, on a calm day by machine. D. One half the seed shall be sown in one direction and the other half at right angles. Seed shall be raked lightly into the soil to a depth of l/4-inch and rolled with a roller weighing not more than l00 pounds per linear foot of tread. E. The surface shall be kept moist by a fine spray until the grass shows uniform germination over the entire area. Wherever poor germination occurs in areas larger than 3 sq. ft., the Contractor shall reseed, roll, and water as necessary to obtain proper germination. F. The Contractor shall water, weed, cut and otherwise maintain and protect seeded areas as necessary to produce a dense, healthy growth of perennial lawn grass. G. If there is insufficient time in the planting season to complete the fertilizing and seeding, permanent seeding may be left until the following planting season, at the option of the Contractor or as required by the Engineer. In that event, a temporary cover crop shall be sown. This cover crop shall be cut and watered as necessary until the beginning of the following planting season, at which time it shall be plowed or harrowed into the soil, the area shall be fertilized and the permanent seed crop shall be sown as specified. 3.03 PLACING MULCH: A. Straw Mulch shall be loosely spread to a uniform depth over all areas designated on the plans, at the rate of 4-1/2 tons per acre, or as otherwise required. B. Straw Mulch may be applied by mechanical apparatus, if in the judgment of the Engineer the apparatus spreads the mulch uniformly and forms a suitable mat to control slope erosion. The apparatus shall be capable of spreading at least 80 percent of the hay or straw in lengths of 6-inches or more, otherwise it shall be spread by hand without additional compensation. C. Wood Fibre Mulch shall be uniformly spread over certain selected seeded areas at the minimum rate of 1,400 pounds per acre unless otherwise required. It shall be placed by spraying from an approved spraying machine having pressure sufficient to cover the entire area in one operation. 3.04 SEEDING AND MULCHING BY SPRAY MACHINE: A. The application of lime, fertilizer, grass seed and mulch may be accomplished in one operation by the use of an approved spraying machine. The materials shall be mixed with water in the machine and kept in an agitated state in order that the materials may be uniformly suspended in the water. The spraying equipment shall be so designed that 07/05/2023 02920-6 when the solution is sprayed over an area, the resulting deposits of lime, fertilizer, grass seed and mulch shall be equal to the specified quantities. B. A certified statement shall be furnished, prior to start of work, to the Engineer by the Contractor as to the number of pounds of limestone, fertilizer, grass seed and mulch per 100 gallons of water. C. This statement should also specify the number of square yards of seeding that can be covered with the solution specified above. If the results of the spray operation are unsatisfactory, the Contractor will be required to abandon this method and to appl y the lime, fertilizer, grass seed and mulch by other methods. 3.05 INSPECTION AND ACCEPTANCE: At the beginning of the planting season following that in which the permanent grass crop is sown, the seeded areas will be inspected. Any section not showing dense, vigorous growth at that time shall be promptly reseeded by the Contractor at its own expense. The seeded areas shall be watered, weeded, cut and otherwise maintained by the Contractor until the end of that planting season, when they will be accepted if the sections show dense, vigorous growth.
