2024 Stormwater Inspection L3Harris 20240923 F:\P2012\0090\R28\Deliverables\Report\2024 Stormwater Inspection L3Harris 20240923.Docx 1 L3Harris Facility 50 Prince Street, Northampton, Massachusetts 2024 Stormwater Inspection and Maintenance Review INTRODUCTION On September 23, 2024, Timothy J. St. Germain, P.E. of Fuss & O’Neill, performed a stormwater inspection and reviewed operation and maintenance records of the L3Harris (Maritime Sensors Division, KEO) facility located at 50 Prince Street in Northampton, Massachusetts. Allison Avallon Duke, Manager, Facilities of L3Harris met Mr. St. Germain during the site visit and provided maintenance-related information and records. This stormwater inspection and maintenance review report is for the period October 1, 2023 to September 23, 2024. The following section evaluates each stormwater feature and maintenance requirement of the facility’s operation, maintenance, and inspection agreement (refer to Attachment A) under the Northampton Stormwater Management Ordinance. The facility’s inspection records are included in Attachment B, maintenance records are included in Attachment C, and site inspection photographs are included in Attachment D. L3Harris identified no storm events with recorded 24-hour precipitation greater than 2.5 inches during the period October 1, 2023 to the date of the inspection. SUMMARY Based on the September 23, 2024 inspection, the stormwater infrastructure on the site is in good condition. The facility has maintained the stormwater bioswales, bioretention areas, and detention basin as specified in the Landscape Maintenance Plan. Maintenance activities included routine plant maintenance (including picking up trash, etc.), mowing, weeding, and removal of leaf debris. Landscaping was conducted up to weekly during the summer months. Landscaping invoices are included in Attachment C. L3Harris continues to work closely with their landscaper, Hilltown Tree & Garden LLC (Hilltown) of Chesterfield, Massachusetts, to assist with improving the landscaping and maintenance across the entire site as well as improving the vegetation on the eastern side. Hilltown is actively assessing the landscaping including invasive species and is developing strategies to improve the long-term viability of native vegetation and stormwater system functionality. Additional landscaping over the past year has included planting of 16 trees (including river birch, eastern red cedar, tupelo, elm, swamp white oak bald cypress and sycamore) and 40 shrubs (aronia, clethra, winterberry holly, potentilla, 9 bark, witch-hazel, bayberry and elderberry). As reported in 2021, the area in the front of the building (refer to photographs showing the front beds at the entrance area as well as CB-12 and CB-13 in Attachment D) had been overtaken by an invasive species (i.e., horsetail). In response, this area had been treated to eliminate the vegetation. In 2022, the invasive species had been eradicated and 1/3 of the area from the front lobby to CB-13 has been replanted with a diverse mix of grasses (2200 new plugs and 250 replacement plugs which did not winter over), which replaces the dominant use of Carex. The diverse plantings are intended to strengthen the vegetation and prevent future invasives. In 2023, L3Harris continued the replanted program with approximately 1/3 of the original area replanted with a diverse mix a vegetation including 2,000 perennials (350 eurybia divaricate – white wood aster; 350 symphyotrichum cordifolium – bluewood aster; 250 eupatorium penfoliatum – boneset; 150 eutrochium fistulosum – hollow stem Joe-Pye weed; 250 chelone glabra – turtlehead; 150 rudbeckia laciniata – green headed coneflower; 150 coreopsis F:\P2012\0090\R28\Deliverables\Report\2024 Stormwater Inspection L3Harris 20240923.Docx 2 lanceolata – lance leaved coreopsis; and 350 – echinacea purpurea – eastern purple coneflower). In 2024, L3Harris continued the replanted program with the planting of 2,000 perennials over a 2,500 square foot area. The new plantings appear to be thriving. These plantings are included in photographs provided in Attachment D. As shown in the photographs, a small area remains unplanted, but it is L3Harris’ intention to modify the shipping/receiving area, which would impact the unplanted area. L3Harris reported and provided invoices to document that the catch basins were cleaned out on December 5, 2023, May 1, 2024 and September 3, 2024 and paved areas swept on December 15, 2023, April 11, 2024 and September 3, 2024. The facility conducts detailed quarterly stormwater inspections of the site in accordance with the requirements of the EPA Multi-Sector General Permit and conducts routine inspections of the site, including inspection of the bioretention areas, the outlet control structures, the Vortechs® unit, and Detention Basin No. 6. Wayfinding posts with identification numbers are installed at each of the catch basins and bioretention areas to facilitate site inspections. In 2010, the facility transitioned from a sand and salt mixture to salt only for de-icing of paved areas. Since no sand is applied to paved areas, there is very little sediment buildup in the catch basins. There was no sediment observed in the gravel filter strip inlet areas to the bioswales and bioretention areas, and little to no sediment in the pervious areas of the bioswales or bioretention. The bioswales and bioretention areas on the site have adequate vegetation growth in most areas, with the exception of the bioretention areas CB-20, CB-22, and CB-23. As reported in previous years, these basins are non-infiltrating basins and the high volume of runoff the areas receive is likely limiting vegetation growth. During July 2018, CB-22 was transitioned to a ¾-inch gravel bed to see how the vegetation grows and if erosion decreases. This area appeared to be stable at the time of the September 23, 2024 inspection. Photographs of the areas are included in Attachment D. Overall, the vegetation density in the bioswales and bioretention areas has increased since previous stormwater inspections, with fuller vegetation and more cattails, sedges, and grasses filling the swales. The increased vegetation density helps to increase the stability of the soils and enhance pollutant removal. Although there was no evidence of erosion in the bare spots observed in bioretention areas CB-20, CB-22 and CB-23, a denser stand of vegetation is recommended consistent with the original landscaping plan, which L3Harris has been working to address. F:\P2012\0090\R28\Deliverables\Report\2024 Stormwater Inspection L3Harris 20240923.Docx 3 INSPECTION RESULTS The inspection results are presented in the same format as the “Stormwater Facility Maintenance Schedule” included in the facility Stormwater Management Plan (See Attachment A). The requirement for each stormwater management structure is provided in italics, followed by the inspection results in the accompanying text box. Parking Lot Sweeping The parking lots and paved areas will be swept a minimum of twice per year, including once in the spring soon after snow melt. Any sediment collected will be transported and disposed of off-site in accordance with applicable regulations. The paved areas on the site were swept three times in the past year – December 15, 2023, April 11, 2024 and September 3, 2024. The invoices for the parking lot sweeping services are included in Attachment C. Catch Basins and Manholes Inspect semi-annually and after any storm event where 2.5 inches, or more, of rain falls within a 24-hour period. Clean structures to remove any accumulated sediment and floatables which inhibit the flow through the structure. Catch basins shall be cleaned twice per year, once in the spring (April -May), and once in the fall (October-November). Sediment and debris shall be transported and disposed of off-site in accordance with applicable regulations. L3Harris identified no storm events with recorded 24-hour precipitation greater than 2.5 inches during the period October 1, 2023 to the date of the inspection. [It should be noted that due to staffing changes, records of semi-annual inspections of catch basins and manholes could not be provided by L3Harris at the time of the inspection. L3Harris is working to correct this oversight.] The catch basins were cleaned out three times in the past year - December 5, 2023, May 1, 2024 and September 3, 2024. The invoices for these services are included in Attachment C. All Bioswales and Bioretention Areas Inspect quarterly upon completion of construction activities. Observe that the bioswales and bioretention areas are operating as intended. The bioswales are designed to collect and convey stormwater from the parking lots to the bioretention areas. The bioretention areas are designed to collect, store and infiltrate stormwater conveyed from the bioswales until the stormwater fills to the elevation of the catch basin grate in the bioretention area. Failure of the bioretention areas can occur if sediment and debris is allowed to build up to the point where infiltration and plant growth is inhibited. Therefore, the bioswales and bioretention areas must be routinely inspected for sediment and debris build-up and erosion on the above established schedule. If there is accumulation of sediment and debris over 2 inches in depth in any area, the sediment and debris shall be removed, transported and disposed of off-site in accordance with applicable regulations. Inspect gravel filter strips at curb inlets and remove debris and sediment build-up. Gravel shall be added to the filter strips as required to maintain the minimum 8-inch wide x 8-inch deep dimensions. F:\P2012\0090\R28\Deliverables\Report\2024 Stormwater Inspection L3Harris 20240923.Docx 4 During winter months, maintain breaks in curbing free from snow and ice to allow proper drainage. Snow shall not be plowed or stored in the bioswales or bioretention areas. The vegetation in the bioswales and bioretention areas shall be inspected and maintained in accordance with the Landscape Maintenance Plan on the following schedule: Spring - identify and replace dead plants, prune broken or dead branches from woody plant materials, remove leave accumulations, and re-seed bare native grass areas. Mulch shall be replaced in the bioretention areas every two years in the spring. Summer - inspect plant materials for signs of pest infestation or disease, remove weeds, and prune plants as necessary to maintain clearances for parking. Fall - remove leaf accumulation and trim native grass to a height of no less than 6-inches. All bioswales and bioretention areas including CB-5, CB-6, CB-7, CB-8, CB-9, CB-10, CB-11, CB-12, CB-13, CB-17, CB-18, CB-20, CB-21, CB-22, CB-23, and CB-24 were inspected during the site visit on September 23, 2024 and were found to be in good condition. Site inspection photographs are contained in Attachment D. No sediment was observed within the gravel filter strip inlet areas on the eastern or western side of the facility. The gravel filter strips at the curb cut inlets were observed to be in good condition. The filter strips were observed to be at least 8 inches wide and are believed to be approximately 8 inches deep. The facility intends to continue to maintain the gravel filter strips on a 5-year schedule by removing the stone and clearing sediment buildup. Little to no sediment was observed within the bioswales and bioretention areas. The facility transitioned from a sand and salt mixture to salt only for de-icing of paved areas in 2010, which has decreased the rate at which sand accumulated in the inlet areas and bioretention or bioswale areas. As has been the case for several years, CB-19 has transitioned from a bioretention area to a wet detention basin with permanent standing water (note: this area appeared to be dry during the September 23, 2024 inspection likely as a result of the extended drought from mid-August through the date of the inspection). The area is located on the edge of the site and is providing habitat value, nutrient removal, and peak flow reduction. Although the area was originally intended as a bioretention area, the basin is not included in the site water quality volume treatment calculations, which the Northampton Department of Public Works approved in a letter dated May 17, 2012. Therefore, no changes are recommended to the basin. The facility has maintained the stormwater bioswales and bioretention areas as specified in the Landscape Maintenance Plan through routine plant maintenance, mowing, weeding, and removal of leaf debris. Landscaping invoices are included in Attachment C. The use of mulch was discontinued in the parking lot bioswales in 2010 since the mulch tends to float in the stormwater and clogs the catch basin grates. The mulch has been replaced with river stone in a few additional locations to minimize erosion potential. The bioswales and bioretention areas were inspected by facility personnel, and completed inspection checklists are included in Attachment B. Bioswales and bioretention areas (CB-5, CB-6, CB-7, CB-8, CB-9, CB-10, CB- 11, CB-12 and CB-13) are inspected routinely by facility personnel. [It should be noted that due to staffing changes, records of quarterly inspections at CB-17, CB-18, CB-20, CB-21, CB-22, CB-23 and CB-24 could not be provided by L3Harris at the time of the inspection. L3Harris is working to correct this oversight.] F:\P2012\0090\R28\Deliverables\Report\2024 Stormwater Inspection L3Harris 20240923.Docx 5 Parking stalls located between the parking islands on the western side of site are used for snow storage. Snow is not placed within bioswales or bioretention areas. The bioswales and bioretention areas on the site have adequate vegetation growth in most areas, with the exception of bioretention areas CB-20, CB-22, and CB-23. As reported in previous years, these non- infiltrating basins receive large runoff volumes, which is believed to limit vegetation growth. In July 2018, the facility began testing the use of ¾-inch gravel in CB-22 to increase vegetation density and reduce erosion. Overall, the vegetation density in the bioswales and bioretention areas has increased since previous stormwater inspections, with fuller vegetation and more cattails, sedges, and grasses filling the swales. The increased vegetation density helps to increase the stability of the soils and enhance pollutant removal. Bioretention Areas in Front Parking Lot Which Provide Infiltration (CB-5, CB-6, CB-7, CB-8, CB-9, CB-10, CB-11, CB-12, CB-13) In addition to the inspection and maintenance requirements detailed above for all bioswales and bioretention areas, those bioretention areas in the front parking lot which are designated to provide infiltration shall be subject to the following additional inspection and maintenance requirements. During the first two months of operation following construction, the bioretention areas in the front parking lot shall be inspected after every rainstorm where 2.5 inches or more rain falls within a 24-hour period. The approximate elapsed time from the end of the storm until there is no longer standing water shall be recorded for each bioretention area in the front parking lot. An infiltrating bioretention area shall be deemed to be not functioning correctly if it takes longer than 72 hours to drain completely following the end of a rainstorm. If an area is not functioning correctly the following steps shall be taken to restore the infiltration properties of the bioretention area. • Remove any sediment accumulations from the areas which are not draining. Re-check standing water duration following next significant storm. • If sediment accumulation removal does not restore the infiltration characteristics of the bioretention area, loosen the topsoil and subsoil by tilling, harrowing, or overturning the material in the problematic areas. Vegetation should be removed prior to disturbing the soils if possible. Following disturbance, replant and/or replace the vegetation and mulch. • If sediment removal and soil loosening efforts do not restore the required infiltration properties, the upper 30-inches of soil should be removed and replaced with new engineering planting mix consisting of 40% sand, 20% topsoil, and 40% compost. Vegetation should be removed prior to excavation if possible. Following replacement of the soil, replant and/or replace the vegetation and mulch. Stormwater Pollution Prevention Plan Inspection Reports (Attachment B) indicate that no standing water for greater than 72 hours within bioretention areas CB-5, CB-6, CB-7, CB-8, CB-9, CB-10, CB-11, CB-12, or CB- 13 during the past year has been observed. Refer to the inspection evaluation in the previous section for additional information. L3Harris identified no storm events with recorded 24-hour precipitation greater than 2.5 inches during the period October 1, 2023 to the date of the inspection. F:\P2012\0090\R28\Deliverables\Report\2024 Stormwater Inspection L3Harris 20240923.Docx 6 Vortechs® Treatment Unit (WQS-1) Inspect semi-annually upon completion of construction activities. Observe that the unit is operating as intended and that there is no structural damage or wear that should be corrected. Inspection results and maintenance work should be recorded on the Vortechs® inspection and maintenance log included with this document. All chambers of the unit should be checked for sediment buildup during the routine inspection. The Vortechs® unit should be cleaned out with a vacuum truck immediately in the event of a spill in the parking lots or loading dock area, when the depth of sediment has accumulated to within 12 to 18 inches of the dry weather surface water elevation in the swirl chamber, or a minimum of once per year. If present, sediment should also be removed from the baffle chambers during the cleaning process. Cleaning should be performed during dry weather conditions when no flow is entering the system. All material removed from the Vortechs® unit should be disposed of off-site in accordance with applicable regulations. The Vortechs® unit was inspected during the biweekly site inspections conducted by facility personnel (Attachment B). Records of the depth of water and depth to sediment were recorded. The sediment depth has consistently been less than 4 inches. The three chambers of the Vortechs® unit were cleaned using a vacuum truck at the same time as the catch basin cleaning. Outlet Control Structures (OCS-1, OCS-3) Inspect semi-annually upon completion of construction activities and after any storm event where 2.5 inches, or more, of rain falls within a 24-hour period. Observe that the outlet control structures are operating as intended. The outlet control structures are designed to detain and control the outflow of stormwater at certain points in the stormwater management system. These structures should be inspected for sediment, debris build-up, and damage. Sediment and debris should be removed during the routine inspection so that there is no interference with the intended operation of the structure. Sediment and debris should be transported and disposed of off-site in accordance with applicable regulations. OCS-1 and OCS-3 were inspected for depth of sediment, debris, and damage during the site visit on September 23, 2024. Sediment depth was less than 1-inch and there was no observed debris or damage to the units. [It should be noted that due to staffing changes, records of semi-annual inspections at OCS-1 and OCS-3 could not be provided by L3Harris at the time of the inspection. L3Harris is working to correct this oversight.] Subsurface Detention System Inspect semi-annually upon completion of construction activities. Observe that the subsurface detention system is operating as intended and in accordance with manufacturer's requirements. The subsurface detention system is incorporated into the stormwater system to temporarily detain stormwater within the management system. The detention system shall be inspected through the access risers and cleanout ports for sediment and debris build-up and damage. Sediment and debris shall be removed when the depth of material exceeds 15% of the detention system pipe diameter. F:\P2012\0090\R28\Deliverables\Report\2024 Stormwater Inspection L3Harris 20240923.Docx 7 Sediment and debris shall be removed from the subsurface system through the access risers and the cleanout ports using a vacuum truck. Manual cleaning through the access ports may be required if it is determined that large debris is present in the system. Only certified confined space entry personnel shall enter the system for manual cleaning. Sediment and debris shall be transported and disposed of off-site in accordance with applicable regulations. The Subsurface Detention Systems located on the eastern and southern sides of the building were inspected for depth of sediment, debris build-up and damage during the site visit on September 23, 2024. No debris or sediment was observed in the systems; therefore, sediment removal is not required at this time. No damage was observed. [It should be noted that due to staffing changes, records of semi-annual inspections at SSD1 and SSD2 could not be provided by L3Harris at the time of the inspection. L3Harris is working to correct this oversight.] Detention Basin No. 6 Inspect semi-annually upon completion of construction activities and after any storm event where 2.5 inches, or more, of rain falls within a 24-hour period. Particular attention should be paid to the condition of the basin outfall area following large storm events. Access for inspection and maintenance of the basin shall be across the grassed slope from the fire lane along the south side of the L3Harris facility. The detention basin shall be inspected for debris and sediment build-up, erosion, health of vegetation, and settlement. General trash and debris shall be removed on a semi- annual basis. If erosion is found it should be repaired utilizing loam, seed, and erosion control blankets, as necessary. Sediment shall be removed from the main basin area when it reaches a depth of 6-inches, but not less than once every five years. Sediment shall be removed from the forebay when it reaches a depth of 6-inches, but not less than once every year. Sediment and debris shall be transported and disposed of off-site in accordance with applicable regulations. The outlet control structure and downstream swale including the weir, outlet pipes, and rip rap channel shall be inspected for signs of deterioration, clogging, or erosion. Outlet pipes shall be cleaned and erosion shall be repaired with additional rip rap or loam, seed, and erosion control blankets as necessary. The basin vegetation shall be mowed and/or trimmed on a semi-annual basis to a height of no less than 4- inches. F:\P2012\0090\R28\Deliverables\Report\2024 Stormwater Inspection L3Harris 20240923.Docx 8 Detention Basin No. 6 was inspected during the site visit on September 23, 2024 with respect to debris and sediment build-up, erosion, the health of the vegetation, and settlement. Overall, the basin was found to be in good condition. Site inspection photographs are provided in Attachment D. The results of inspections completed by facility personnel (Attachment B) indicate no issues within the last year. L3Harris identified no storm events with recorded 24-hour precipitation greater than 2.5 inches during the period October 1, 2023 to the date of the inspection. At the time of the site visit, there was no evidence of debris or clogging of the inlet or outlet structures or within the basin. There are some vegetation located near the low-level outlet intake pipe, although they do not appear to be impacting the flow path. Maintenance of the forebay or basin is not required at this time. The vegetation around the edge of the basin is mowed routinely for access. The gravel located at the inlet to the pond and the gravel placed in the downstream channel are working to minimize erosion of the inlet and outlet to the pond. The vegetation within the basin is healthy and is well-established. Areas Downstream of Detention Basin No.6 Inspect semi-annually upon completion of construction activities. The 18-inch inlet at Grove Street shall also be inspected after any storm event where 2.5 inches, or more, of rain falls within a 24-hour period. Flow from detention basin no 6 leaves the rip rap outlet pad and travels through a small wetland area to an 18-inch diameter reinforced concrete drainage system inlet adjacent to Grove Street. A portion of the outflow from the basin is also directed by a small vegetated berm to a drainage channel which runs parallel to the driveway for 91 Grove Street before discharging to the drainage system inlet. This small berm was constructed to prevent the detention basin outflow from entering the back parking area for 91 Grove Street. The vegetated berm, small channel, and general grading of the wetland area must be maintained so that drainage flows are directed to the rip rap basin and 18-inch inlet and not to the paved parking area at 91 Grove Street or to the Grove Street roadway. The wetland area between the basin outfall and the drainage system inlet, the vegetated berm, and the small channel along the 91 Grove Street driveway should be inspected on a semi-annual basis for erosion. If erosion is found it should be repaired utilizing loam, seed, and erosion control blankets. Approval from the Conservation Commission may be necessary prior to undertaking work within the designated wetland area. The 18-inch inlet to the Grove Street drainage system should also be inspected for sediment build-up and clogging. If sediment or debris reaches a depth of 6-inches or more in the small rip rap basin at the inlet it should be removed and disposed of off-site in accordance with applicable regulations. An easement for access to the property at 91 Grove Street for inspection and maintenance of the drainage system components has been prepared and a sketch detailing the limits of this easement is attached. All maintenance work and access shall be performed in accordance with the requirements of the easement agreement.

The outlet control structure and downstream swaie including the weir,outlet pipes,and rip rap channel shall be inspected for signs of deterioration,clogging,or erosion.Outlet’pipes shall be cleaned and erosion shall be repaired with additional rip rap or loam,seed,and erosion control blankets as necessary. The basin vegetation shall be mowed and/or trimmed on a semi—annual basis to a height of no less than 4—inches. Areas Downstream of Detentipn Basin No.6 Inspect semi—annually upon completion of construction activities.The 18-inch inlet at Grove Street shall also be inspected after any storm event where 2.5 inches,or more,of rain falls within a 24-hour period. Flow from detention basin no.6 leaves the rip rap outlet pad and travels through a small wetland area to an 18-inch diameter reinforced concrete drainage system inlet adjacent to Grove Street.A portion of the outflow from the basin is also directed b.y a small vegetated berm to a drainage channel which runs parallel to the driveway for 91 Grove Street before discharging to the drainage system inlet.This small berm was constructed to prevent the detention basin outflow from entering the back parking area for 91 Grove Street.The vegetated berm,small channel,and general grading of the wetland area must be Page 4 of 5 maintained so that drainage flows are directed to the rlp—rap basin and 18-inch inlet and not to the paved parking area at 91 Grove Street or to the Grove Street roadway. The wetland area between the basin outfall and the drainage system inlet,the vegetated berm,and the small channel along the 91 Grove Street driveway should be inspected on a semi~annual basis for erosion.If erosion is found it should be repaired utilizing loam,seed, and erosion control blankets.Approval from the Conservation Commission may be necessary prior to undertaking work within the designated wetland area. The 18-inch inlet to the Grove Street drainage system should also be inspected for sediment build—up and ciogging.If sediment or debris reaches a depth of 6—inches or more in the small rip rap basin at the inlet it should be removed and disposed of off—site in accordance with applicable regulations.. An easement for access to the property at 91 Grove Street for inspection and maintenance of the drainage system components has been prepared and a sketch detailing the limits of this easement is attached.All maintenance work and access shall be performed in accordance with the requirements of the easement agreement. Record Keeping and Annual Reports Records shall be maintained by Kollmorgen Electro—Optical at their offices as described above and shall document all routine and emergency maintenance work performed on the stormwater management system and shall bear the signature of the individual supervising the work.Annual reports documenting the inspection and maintenance of the stormwater management system shall be certified by a registered professional engineer or other qualified stormwater professional,as approved by the Northampton Department of Public Works.Annual reports shall be submitted to the Northampton Department of Public Works and the Northampton Office of Planning and Development no later than October 1*‘of each year._A _ Page 5 of 5 |gdO u|_EQ_EHvfigZ02gm__wZ2 _=§_\___EZQFH6wEUIW ZOF<QE_n_O_2X005 UZESIEGS:Dmmsml Q SW350D5mzaé iéidifl§_§En_ H -_ = u i -II. gmggmmmmg____oEEm___H__°Z_______mmN___> _3_ao_O_:8_m r_%__OE__8__5?‘K kMfl_F___“___>‘Vw_L§,_>“Q§l_;_vu_ _g I__%_____uy _\“__y§ __ NEE ___g§_§_m§__$;S£_N$53m__m_w___tNMwm:€_uE$gEM__°____§_____8SENus9_u‘M55135 :2>__VaEM>gtUCkSE3 _‘ _IQBB!I>Z_O62"5G505">___g:8HSEH -‘ Na!I>Z_fig“I5 “TI: BN2H__E 2'23 35H>___22M__E> Eli $62I2_:2H5 NTIE‘ §:_§I>Z_GW_ZV_qh=H2_:2ISE :42 DJ:I)5Mg:ISE_ g|§ _figH2 SEI___~_ NIX} $2U2:2n:2 7% s‘NO_">2_£2IIE Eli cud!‘>Z_E2HSE fill: Eé8g_H>Z_S5_=_M_H>Z_ B52uHE ‘#43 fig‘EH>Z_ Qéfiz">Z_22BE T; 32H>___3:HE “N18 32H>___52"5 gig 22I>___:2HN3>NEE“H25: 3&0 gm:n>3fig"Ma 3'8 gsI2:2I5 5'8 UN‘:H>___32|% his 22I>___32HMa_ Elm“ :2I>___:2“5 zlfi 32H>1Nd:I5 2'5 :g_n>5SEHg N75 " D:N>Z_ T85_ :2“>Z_Q2:'E GT8 lgH>___f X>Y‘\\_\\\_|‘y\\_‘\\ _\\HMUm\“_____\____:_\\\:____>_\X:5;\‘N92_2;;__’/V/’H'/,0,// ///I__ {llI_‘IHILH/:__\\\_“}‘:\\\\__‘_\‘I,\\\\_‘_\“““““I!‘\__\_\‘/I’‘_\\_\\\_\ ,\\ ___/X/_,H/_~;_’\‘_';,,”jl/I_\lI‘K____V, _\/__ 2E55mamagm855*:__ M \__‘\\_____ \__\_\___ \\\_\\\\ i_m__\v I__H’//If/_//_/////H/H,NI}/1//"l’,/’_’I/1‘/ “__\___M__ \___ v_HH/I’//,//H]/(/__\ //H'%%U%M(I///“_ I/I'1//7I/’_O12_/’///M//H//I//,/_____I/I‘Ia,/ _2°4_u¢E_'/7,,17 :2HS_‘ Z“\‘ \ ____w_I>_______FIEH5______> “I8__ :2n>___\\“K:2u5\___M_\__‘\ TS\_____\ “£2H>___\\_‘‘_EEIE\>_\__\_\__\\__ “'8\_\\__\4_‘_____\_\_\ V_\__________~_\\‘_X_U'g_":_______:____\__‘\___\\Ix_\\_>”___\\8Egg3‘)‘gm’\pans_\_‘\____\\___:_%X\\__v~“-\\_ isbi_____\\_\G___>'3‘‘ N__°_|>___\J_\_>__\\____\__\\_\\_‘K).v_____N_g__“8_\>____\_\______Q\4__R‘\_\_\F__;:"'“v‘_“_m,/’W_\“H“",‘N_kI_ InQ\Fl\_\\_____\\__\‘_A_ __\_\_\__\__\_____T__\__\\\_I_\“_W‘___WC"'______U>‘_\“_$__%__\_\\__\__\___"__\\_\_\\__\‘_0_7_V‘Nag:y_ 3\_4\\___\_A :2Hi_\___\\__‘___‘____(\_5:‘UH3L‘W>v_v___v“Wmv_YE2__E_\_\\\_\:_\_no______v_“_‘_V%%w1UH_mnumP'wA§__v____h>__\_’_v__h NIB\_\\\_‘_\\_\’___\\V‘__m‘F___M¢_‘H\__“vm(m_E:m"A_$H_$wHv%h>__>‘:_Hw_>‘__4‘_v___>>>__H‘__ _~__‘_\__\‘__‘__‘‘_;‘;_HU”"_nfl1s°V_MW_agEMR_h‘__H_|_ °>Nm_">____\\\X“H*_\_‘\\_wY5_1‘U_'_w____uh?"___\U._°z_E°U_‘u.E_°_bw__aw_,___:__Z‘_“_‘__>_H_qmgflE_\\\\C‘\\V\V/‘5_lP,___1111'-J1--wVr41,l“-V-“v10_‘_‘vH_vMH>_'Y_HIL_vInto/V:__>_,‘_N TSh\‘\__‘‘_‘\\\\‘‘_\V/~H‘H|_>_:_>_h‘:‘d_H_Uh_?v_vHOV_/WW‘; _9I_\_:__XX‘\___’_____‘_>O_Y_@Mywt\___\‘‘/__oi‘Zan____HI’'1‘h__n_\_at____\\\_____<r__)_H\*v_‘_‘___'_;__‘______/HH‘_‘_H__‘>_‘_fi\_“\\ “law:32:maZ'_____Qx\_____\__at‘MW¥m_(_mw_MEMMw_hH_\“_H\M_$_“m‘HQHJM__‘__>H_§_;\>H>H‘\_‘H_vw_____H_>é_‘“““>&“1I__)Y("J“QM oz:3‘E__“§ux_auKt:_w_mw8__B5ME=5Eb:__l_(___m_§gE_5ou_\_\_____\\n\'___‘r\“__‘_HHMR/_“_‘u_“y“H‘__H’_'__V‘___/__MvHm___”v_,‘N__"WV‘_W‘HA\,'U_'m,_\>O\.

The water depth to sediment is determined by taking two measurements with a stadia rod:one measurement from the manhole opening to the top of the sediment pite and the other from the manhole opening to the water surface.if the difference between these measurements is less than eighteen inches the system should be cieaned out.Note:To avoid underestimating the volume of sediment in the chamber,the measuring device must be carefully lowered to the top of the sediment pile. For optimum performance,the system should be cleaned out when the floating hydrocarbon layer accumulates to an appreciable thickness.in the event of an oil spill,the system should be cleaned immediately. 7 ATTACHMENT B STORMWATER MANAGEMENT OPERATION, MAINTENANCE,AND INSPECTION AGREEMENT Pertinent Drainage Easements: 1.Easement to discharge to Basin 5 is contained in the Kollmorgen
