Disposal of the accumulated sediment and hydrocarbons must be in accordance with applicable local, state, and federal guidelines and regulations. The logs shall be made accessible to the Town of North Andover upon request. Inspection and Maintenance Frequency and Corrective Measures: The following areas, facilities and measures will be inspected, and any identified deficiencies will be corrected. Clean out must include the removal and legal disposal of any accumulated sediments and debris in accordance with applicable local, state, and federal guidelines and regulations. 1. Parking Lot Sweeping Sweeping shall be done once in the early fall and then immediately following spring snowmelt to remove sand and other debris and any time when visual buildup of debris is apparent. At a minimum, the schedule for street sweeping shall be done quarterly with a high efficiency vacuum sweeper. Pavement surfaces shall be swept at other times such as in the fall after leaves have dropped to remove accumulated debris. Since contaminants typically accumulate within 12 inches of the curbline, sweeping operations should concentrate on cleaning curb and gutter lines for maximum pollutant removal. Once removed from paved surfaces, the sweepings must be handled 11MFS1Company_Data\Projects\Eng14570191Drainage\Rev 2\457019 Operation And Maintenance Manual-RevIDoe 2 and disposed of properly. Disposal of the accumulated sediment and hydrocarbons must be in accordance with applicable local, state, and federal guidelines and regulations. 2. Deep Sump Hooded Catch Basins Inspect catch basins at least 4 times per year including at the end of the foliage and snow removal seasons (late fall and early spring) to ensure that the catch basins are working in their intended fashion and that they are free of debris. Sediment must be removed whenever the depth of deposits is greater than or equal to one half the depth from the bottom of the invert of the lowest pipe in the basin. If the basin outlet is designed with a hood to trap floatable materials, check to ensure watertight seal is working. Damaged hoods shall be repaired or replaced. At a minimum, remove floating debris and hydrocarbons at the time of the inspection. Sediment and debris can be removed by a clamshell bucket; however a vacuum truck is preferred. Disposal of the accumulated sediment and hydrocarbons must be in accordance with applicable local, state, and federal guidelines and regulations. 3. Vegetated Areas Inspect slopes and embankments early in the growing season to identify active or potential erosion problems. Replant bare areas or areas with sparse growth. Where rill erosion is evident, armor the area with an appropriate lining or divert the erosive flows to on-site areas able to withstand the concentrated flows. 4. Snow Storage and Removal Proposed snow storage areas are show on the site plan. During the winter months all snow is to be stored such that snowmelt is controlled. In the event the amount of snow exceeds such capacity, it is to be removed off-site. The minimum amount of deicing chemicals needed is to be used. Do not dispose of snow on top of storm drain catch basins or in stormwater drainage swales or ditches. 5. Hydrodynamic Separator (First Defense Unit) Initial maintenance to be performed every six months for the first year after the unit is online and operational. A vacuum truck must be used at a minimum of once per year to remove floatables & sediment accumulation. Refer to the attached First Defense Owner's manual for operation and maintenance procedures and schedules thereafter. Additionally, the unit shall be inspected based on the below criteria: • Remove oil and floatables following a spill in the drainage areas. • Remove sediment following a spill in the drainage area. 6. Subsurface Stormwater Infiltration Systems All subsurface systems should initially be inspected within the first three months after completion of the site's construction. Preventive maintenance should be performed at least every six months and sediment shall be removed from pretreatment BMP`s as necessary. The Infiltration System shall be inspected on regular bi-annual scheduled dates. During the first year of operation, the system shall be inspected after at least two large storm events (> I inch)to ensure that it is fully drained within 72 hours. If standing water is present more than 72 hours after a rainfall event, the infiltration system shall be cleaned. 11MFS1Company_Data\Projects\Eng14 5 70 1 9113rainage\Rev 2\457019 Operation And Maintenance Manual-RevlDoc 3 Ponded water in the system indicates potential infiltration failure in the bottom of the pipe and/or stone. In this case, accumulated sediment shall be removed from the bottom utilizing water jets and/or truck mounted vacuum equipment. Sediment and debris removal should be through the use of truck mounted vacuum equipment. Outlet pipes should be flushed to point of discharge on the same frequency as mentioned above. Disposal of the accumulated sediment and hydrocarbons must be in accordance with applicable local, state, and federal guidelines and regulations. The following is the recommended procedure to inspect the underground system in service: 1. Locate the riser or cleanout section of the system. The riser/cleanout will typically be 6 or 12" in diameter or larger. 2. Remove the lid from the riser/cleanout. 3. Measure the sediment buildup at each riser and cleanout location. Only certified confined space entry personnel having appropriate equipment should be permitted to enter the system. 4. Inspect each manifold, all laterals, and outlet pipes for sediment build up, obstructions, or other problems. Obstructions should be removed at this time. 5. If measured sediment build up is between 2" to 8", cleaning should be considered; if sediment build up exceeds 8", cleaning should be performed at the earliest opportunity. A thorough cleaning of the system (manifolds and laterals) shall be performed by water jets and/or truck mounted vacuum equipment. Pretreatment BMP's shall be inspected and cleaned during the regular bi-annual inspections. The inlet and outlet of the subsurface systems should be checked periodically to ensure that flow structures are not blocked by debris. All pipes connecting the structures to the system should be checked for debris that may obstruct flow. 7. Filterra®Bioretention Units During the first year of operation the Filterra® Bioretention units shall be inspected after at least two large storm events (>l inch)to ensure proper operation. Refer to the attached Filterra®maintenance procedures for additional information. \\MFS\Company_Bata\Projects\Eng\4570190rainage\Rev 2\457019 Operation And Maintenance Manual-RevlDoc 4 Long Term Pollution Prevention Plan In accordance with DEP Stormwater Standard 44 the development and implementation of suitable practices for source control and pollution prevention shall be incorporated in a Long Term Pollution Prevention Plan (LTPPP). The primary focus of the LTPPP is to establish procedures and controls E for limiting the potential sources of pollutants, including nutrients that may contribute to excessive contaminant levels in the site's stormwater runoff. To this end the following source controls and procedures will be in place at the site: • Good House Keeping — It shall be the responsibility of the property owner to keep the site clean at all times. • Storing Material and waste products inside or under cover — No material storage is to take place on site. • Vehicle washing—Vehicle washing is not allowed to tape place on premises. • Routine inspections and maintenance of stormwater BMP's —Refer to the Operation and Maintenance procedures for each BMP as described in the O&M Plan. • Maintenance of lawns, gardens and other landscaped areas — All landscaping and maintenance to be performed by an authorized company chosen by the property owner. • Storage and use of fertilizers, herbicides and pesticides—All landscape maintenance will be conducted by an authorized company chosen by the property owner. Any application of herbicides or pesticides will be applied by a licensed applicator. There will be no on-site storage of fertilizers, herbicides and pesticides. • Proper management of deicing chemicals and snow — Deicing chemicals and snow removal shall be conducted by an authorized company chosen by the property owner. • Nutrient management plan- The goal of the nutrient management plan is to minimize the potential sources of excess nutrients on the site and the release of nutrients in the stormwater from the site. In general, the nature of the site use will tend to reduce the nutrients in the stormwater. Further,procedures indicated above or in the O&M Plan related BMP maintenance procedures, and street sweeping will act to reduce the levels of nutrients in the stormwater, and the nutrients entering the adjacent wetland and the groundwater. 11MFs1Company DatalProjectsTng14570191DrainagelRev 2\457019 Operation And Maintenance Manual-RevlDoc 5 N` ,!

First Defense's by Hydro, International Introduction Applications The First Defense' is an enhanced vortex separator •Stormwater treatment at the point of entry into the drainage line that combines an effective and economical stormwater Sites constrained by space,topography or drainage profiles f of cover depth and a treatment chamber with an Integral peak flow bypass. It with limited slope p i efficiently removes total suspended solids (TSS), trash and .Retrofit installations where stormwater treatment is placed on or 1 hydrocarbons from stormwater runoff without washing out tied into an existing storm drain line previously captured pollutants.The First Defense"is available •Pretreatment for filters,infiltration and storage In several model configurations (refer to Section A Model Sizes & Configurations, page 4) to accommodate a wide Advantages range of pipe sizes,peak flows and depth constraints. • Inlet options include surface grate or multiple inlet pipes • Integral high capacity bypass conveys large peak flows without the need for"offline"arrangements using separate junction Operation manholes The First Defense`s operates on simple fluid hydraulics. It is self- .Proven to prevent pollutant washout at up to 500%of its activating,has no moving parts,no external power requirement treatment flow i and is fabricated with durable non-corrosive components. .Long flow path through the device ensures a long residence No manual procedures are required to operate the unit and time within the treatment chamber,enhancing pollutant settling maintenance is limited to monitoring accumulations of stored =Delivered to site pre-assembled and ready for installation pollutants and periodic clean-outs. The First DefenseO has been designed to allow for easy and safe access for inspection, i monitoring and clean-out procedures. Neither entry Into the unit nor removal of the internal components is necessary for maintenance,thus safety concerns related to confined-space- entry are avoided. Pollutant Capture and Retention The internal components of the First. DefenseP have been designed to optimize pollutant capture. Sediment is captured and retained in the base of the unit, while oil and#loatables " are stored on the water surface in the inner volume(FIg.1). I Fall The pollutant storage volumes are Isolated from the built-in Oil Storage Depth bypass chamber to prevent washout during high-flow storm events. The sump of the First Defenses retains a standing water level between storm events.This ensures a quiescent flow regime at the onset of a storm, preventing resuspension and washout of pollutants captured during previous events. Sediment +l Accessories such as oil absorbent pads are available for Sediment Storage enhanced oil removal and storage. Due to the separation of the oil and floatable storage volume from the outlet, the potential for washout of stored pollutants between clean-outs Fig.q Pollutant storage volumes in the First Defense". Is minimized. f ,; V51 i Page 14 First Defense"D Operation and. Maintenance Manual II.

Maintenance Overview The First DefenseP Protects the environment by removing a wide range of pollutants from stormwater runoff. Periodic removal of these captured pollutants Is essential to the continuous,long-term functioning of the First DefenseP, The First DefenseP will capture and retain sediment and oil until the sediment and oil storage volumes are full to capacity. When sediment and oil storage capacities are reached,the First DefenseO will no longer be able to store removed sediment and oil, Maximum pollutant storage capacities are provided In Table 1. The First DefenseO allows for easy and safe Inspection,monitoring and clean-out procedures. A commercially or municipally owned sump-vac is used to remove captured sediment and floatables. Access ports are located in the top of the manhole. Maintenance events may include Inspection,Oil&Floatables Removal,and Sediment Removal, Maintenance events do not require entry into the First DefenseP, nor do they require the internal components, of the First DefenseO to be removed. In the case of inspection and floatables removal,a vactor truck is not required. However,a vactor truck Is required If the maintenance event is to include oil removal and/or sediment removal. Maintenance Equipment Considerations The Internal components of the First DefenseO HC have a centrally located circular shaft through which the sediment storage sump can be accessed with a sump vac hose.The open diameter of this access shaft is 15 inches in diameter(Fig.3).Therefore,the nozzle fitting of any vactor hose used for maintenance should be less than 15 inches In diameter. 15-In Maintenance Access i it Fig.3 The central opening to the sump of the First Defenseo-HC is 15 inches in diameter. Determining Your Maintenance Schedule The frequency of clean out Is determined In the field after Installation. During the first year of operation,the unit should be inspected every six months to determine the rate of sediment and floatables accumulation. A simple probe such as a Sludge-Judge can be used to determine the level of accumulated solids stored In the sump. This information can be recorded In the maintenance log(see page 9)to establish a routine maintenance schedule. The vactor procedure,including both sediment and oil/flotables removal,for a 6-ft First DefenseO typically takes less than 30 minutes and removes a combined water/oil volume of about 765 gallons.

Filterra is a specially engineered stormwater treatment system incorporating high performance biofiltration rnedia to rernove pollutants from stormwater runoff. The system's biota (vegetation and soil microorganisms) then further breakdown and absorb captured pollutants. All components of the system work together to provide a sustainable long-term solution for treating stormwater runoff. The Filterra system has been delivered to you with protection in place to resist intrusion of construction related sediment which can contaminate the biofiltration media,and result in inadequate system performance. These protection devices are intended as a best practice and cannot fully prevent contamination. It is the purchaser's responsibility to provide adequate measures to prevent construction related runoff from entering the Filterra system. Included with your purchase is Activation of the Filterra system by the manufacturer as well as a 1-year warranty from delivery of the system and 1-year of routine maintenance (mulch replacement, debris removal, and pruning of vegetation) up to twice during the first year after activation. Design and Installation Each project presents different scopes for the use of Filterra systems. Information and help may be provided to the design engineer during the planning process, Correct Filterra box sizing (by rainfall region) is essential to predict pollutant removal rates for a given area. The engineer shall submit calculations for approval by the local jurisdiction. The contractor is responsible for the correct installation of Filterra units as shown in approved plans. A comprehensive installation manual is available of www.ContechES,com. Activation Overview Activation of the Filterra system is a procedure completed by the manufacturer to place the systern into working condition. This involves the following items: Removal of construction runoff protection devices Planting of the system's vegetation Placement of pretreatment mulch layer using mulch certified for use in Filterra systems. Activation MUST be provided by the manufacturer to ensure proper site conditions are met for Activation, proper installation of the vegetation,and use of pretreatment mulch certified for use in Filterro systems. AVP A "...ao 4 wwwContechES,com/fifterra 800-338-1122 Minimum Requirements The minimum requirements for Filterra Activation are as follows: 1 The site landscaping must be fully stabilized, i.e. full landscaping installed and some gross cover not just straw and seed) is required to reduce sediment transport. Construction debris and materials should be removed from surrounding area, 2.Final paving must be completed. Final paving ensures that paving materials will not enter and contaminate the Filterra systern during the paving process, and that the plant will receive runoff from the drainage area,assisting with plant survival for the Filterra system. In 3.Filterra throat opening should be at least 4"in order to ensure adequate capacity for inflow and debris.

Keep in mind that plants are subject to availability due to seasonality and required minimum size for the Filterra systern. Plants installed in the Filterra system are container plants (max 15 gallon) from nursery stock and will be immature in height and spread: at Activation. It is the responsibility of the owner to provide adequate irrigation when necessary to the plant of the Filterra system. The "Planting Requirements for Filterra Systems" document is included as an appendix and discusses proper selection and care of the plants within Filterra systems, Warranty Overview Refer to the Contech Engineered Solutions U-C Stormwater Treatment System LIMITED WARRANTY for further information. The following conditions may void the Filterra system's warranty and waive the manufacturer provided Activation and Maintenance services: • Unauthorized activation or performance of any of the items listed in the activation overview Any tampering, modifications or damage to the Filterra system or runoff protection devices Removal of any Filterra system components • Failure to prevent construction related runoff from entering the Filterra system Failure to properly store and protect any Filterra components (including media and underdrain stone) that may be shipped separately from the vault Routine Maintenance Guidelines With proper routine maintenance, the biofiltration media within the Filterra system should lost as long as traditional bioretention media. Routine maintenance is included by the manufacturer on all Filterra systems for the first year after activation. This includes a maximum of 2 visits to remove debris, replace pretreatment mulch, and prune the vegetation. More information is provided in the Operations and Maintenance Guidelines, Some Filterra systems also contain pretreatment or outlet boys, Depending on site pollutant loading, these boys may require periodic removal of debris, however this is not included in the first year of maintenance, and would likely not be required within the first year of operation, These services, as well as routine maintenance outside of the included first year, can be provided by certified maintenance providers listed on the Contech website. Training can also be provided to other stormwater maintenance or landscape providers. .................. .. .......... 6 wviw,ContechES.com/fi11erro 800-338-1122 Why Maintain? All stormwaier treatment systems require maintenance for effective operation. This necessity is often incorporated in your property's permitting process as a legally binding BMP maintenance agreement. Other reasons to maintain are: • Avoiding legal challenges from your jurisdiction's maintenance enforcement program, • Prolonging the expected lifespan of your Filterra media. • Avoiding more costly media replacement. • Helping reduce pollutant loads leaving your property, Simple maintenance of the Filterra is required to continue effective pollutant removal from stormwater runoff before discharge into downstream waters, This procedure will also extend the longevity of the living biofilter system, The unit will recycle and accumulate pollutants within the biomass, but is also subjected to other materials entering the inlet. This may include trash, silt and leaves etc. which will be contained above the mul'ch layer. Too much silt may inhibit the Filterra's flow rate, which is the reason for site stabilization before activation. Regular replacement of the mulch stops accumulation of such sediment. When to Maintain? Contech includes a 1-year maintenance plan with each system purchase. Annual inducled maintenance consists of a maximum of two (2) scheduled visits.Additional maintenance may be necessary depending on sediment and trash loading (by Owner or at additional cost). The start of the maintenance plan begins when the system is activated. Maintenance visits are scheduled seasonally, the spring visit aims to clean up after winter loads including salts and sands while the fall visit helps the system by rernoving excessive Ileaf litter. It has been found that in regions which receive between 30-50 inches of annual rainfall, (2)two visits are generally required; regions with less rainfall often only require (1) one visit per annurn. Varying land uses can affect maintenance frequency, e.g, some fast food restaurants require more frequent trash removal. Contributing drainage areas which are subject to new development wherein the recommended erosion and sediment control measures have not been implemented may require additional maintenance visits. Some sites may be subjected to extreme sediment or trash loads, requiring more frequent maintenance visits. This is the reason for detailed notes of maintenance actions per unit, helping the Supplier and Owner predict future maintenance frequencies, reflecting individual site conditions. Owners must promptly notify the (maintenance) Supplier of any damage to the plarl which constitutes) an integral part of the bioretention technology. Owners should also advise other landscape or maintenance contractors to leave all maintenance to the Supplier (i.e. no pruning or fertilizing) during the first year. W, 0 4"141 P www.Contecl)ES.com/filter°ra l 800.338-1122 7 Exclusion of Services Clean up due to major contamination such as oils, chemicals,toxic spills, etc. will result in additional costs and are not covered under the Supplier maintenance contract. Should a major contamination event occur the Owner must block off the outlet pipe of the Filterra (where the cleaned runoff drains to, such as drop inlet) and block off the throat of the Filterra, The Supplier should be informed immediately. Maintenance Visit Summary Each maintenance visit consists of the following simple tasks (detailed instructions below). 1. Inspection of Filterra and surrounding area 2. Removal of tree grate and erosion control stones 3. Removal of debris, trash and mulch 4. Mulch replacement 5. Plant health evaluation and pruning or replacement as necessary 6. Clean area around Filterra 7. Complete paperwork Maintenance Tools, Safety Equipment and Supplies Ideal tools include: camera, bucket, shovel, broom, pruners, hoe/rake, and tape measure. Appropriate Personal Protective Equipment (PPE) should be used in accordance with local or company procedures. This may include impervious gloves where the type of trash is unknown, high visibility clothing and barricades when working in close proximity to traffic and also safety hats and shoes. A T-8ar or crowbar should be used for moving the tree grates (up to 170 Ibs ea.). Most visits require minor trash removal and a full replacement of mulch. See below for actual number of bagged mulch that is required in each media bay size. Mulch should be a double shredded, hardwood variety. Some visits may require additional Filterra engineered soil media available from the Supplier. 4 4 4 4 2 6 4 6 6 3 8 4 8 8 4 6 6 9 9 5 8 6 12 12 6 10 6 15 15 8 12 6 18 18 9 13 7 23 23 12 i I 1 I i e www.ContechES.com/filterra 1 800.338-1122 Maintenance Visit Procedure Keep sufficient documentation of maintenance actions to predict location specific maintenance frequencies and needs.

Signature Date 12 wvvw.ContecliES.com/filiefra 1800-338-1122 Appendix 2 - Planting Requirements for Filterra® Systems Plant Material Selection • Select plant(s) as specified in the engineering plans and specifications. • Select plant(s) with full root development but not to the point where root bound. • Use local nursery container plants only. Bail and burlapped plants are not permitted. • For precast Filterra systems with a tree grate, plant(s) must not have scaffold limbs of least 14 inches from the crown due to spacing between the top of the mulch and the tree grate. Lower branches can be pruned away provided there are sufficient scaffold GRAFT branches for tree or shrub development. CROWN • For precast Filterra systems with a tree grate, at the time of installation, it is required _ _ _ _ _SOIL SURFACE that plant(s) must be at least 6" above the tree grate opening at installation for all Filterra configurations. This DOES NOT apply to Full Grate Cover designs. • Plant(s) shall not have a mature height greater than 25 feet. • For standard 21" media depth, a 7— 15 gallon container size shall be used. Media less than 21" (Filterra boxes only) will require smaller container plants. • For precast Filterra systems, plant(s) should have a single trunk at installation, and pruning may be necessary at activation and maintenance for some of the faster growing species, or species known to produce basal sprouts. Plant Installation • During transport protect the plant leaves from wind and excessive jostling. • Prior to removing the plant(s) from the container, ensure the soil moisture is sufficient to maintain the integrity of the root ball. if needed, pre-wet the container plant. • Cut away any roots which are growing out of the container drain holes. Plants with excessive root growth from the drain holes should be rejected. • Plant(s) should be carefully removed from the pot by gently pounding on the sides of the container with the fist to loosen root ball. Then carefully slide out. Do not lift plant(s) by trunk as this can break roots and cause soil to fall off. Extract the root ball in a horizontal position and support it to prevent it from breaking apart. Alternatively the pot can be cut away to minimize root ball disturbance. • Remove any excess soil from above the root flare after removing plant(s) from container. • Excavate a hole with a diameter 4" greater than the root ball, gently place the plant(s). • If plant(s) have any circling roots from being pot bound, gently tease them loose without breaking them. • If root ball has a root mot on the bottom, it should be shaved off with a knife just above the mat line. • Plant the tree/shrub/grass with the top of the root ball 1"above surrounding media to allow for settling. • Ali plants should have the main stem centered in the tree grate (where applicable) upon completion of installation. • With all trees/shrubs, remove dead, diseased, crossed/rubbing, sharply crotched branches or branches growing excessively long or in wrong direction compared to majority of branches. • To prevent transplant shock (especially if planting takes place in the hot season), it may be necessary to prune some of the foliage to compensate for reduced root uptake capacity. This is accomplished by pruning away some of the smaller secondary branches or a main scaffold branch if there are too many. Too much foliage relative to the root ball can dehydrate and damage the plant. • Plant staking may be required, www.ContechES.com/filierra j 800-338-1122 13 Mulch Installation • Only mulch that has been meeting Contech Engineered Solutions' mulch specifications can be used in the Filterra system. • Mulch must be applied to a depth of 3" evenly over the surface of the media. Irrigation Requirements • Each Filterra system must receive adequate irrigation to ensure survival of the living system during periods of drier weather. • Irrigation sources include rainfall runoff from downspouts and/or gutter flow, applied water through the tree grate or in some cases from an irrigation system with emitters installed during construction. • At Activation; Apply about one (cool climates) to two (warty) climates) gallons of water per inch of trunk diameter over the root ball. • during Establishment: In common with all plants, each Filterra plant wile require more frequent watering during the establishment period. One inch of applied water per week for the first three months is recommended for cooler climates (2 to 3 inches for wormer climates). If the system is receiving rainfall runoff from the drainage area, then irrigation may not be needed. Inspection of the soil moisture content can be evaluated by gently brushing aside the mulch layer and feeling the soil. Be sure to replace the mulch when the assessment is complete, Irrigate as needed**. Established Plants: Established plants have fully developed root systems and can access the entire water column in the media. Therefore irrigation is less frequent but requires more applied water when performed, For a mature system assume 3,5 inches of available water within the media matrix. Irrigation demand can be estimated as 1" of irrigation demand per week. I Therefore if dry periods exceed 3 weeks, irrigation may be required. It is also important to recognize that plants which are exposed to windy areas and reflected heat from, paved surfaces may need more frequent irrigation. Long term care should develop a history which is more site specific. i 1 * Five gallons per square yard approximates 1 inch of water Therefore for a 6' by 6' Filterra approximately 20-60 gallons of water is needed.To ensure even distribution of water it needs to be evenly sprinkled over the entire surface of the filter bed, with special attention to make sure the root ball is completely wetted. NOTE; if needed, measure the time it takes to fill a five gallon bucket to estimate the applied water flow rate then calculate the time needed to irrigate the Filterra, For example, if the flow rate of the sprinkler is 5 gallons/minute then it would take 12 minutes to irrigate a 6' by 6'filter. i I • ikyy jr I iVl� � III �r 111 4 i as r%/ g i 1 �r nyrp, 1 14 www.CootcchES.com/filterrta 1 8M338-1122 Notes I f i 1, i i f I' [t e f ra ffiorOe ntron Systems I OWN TECH ENGINEERED SOLUTIONS I I 9025 Centre Pointe drive, Suite 400 West Chester, OH 45069 info0a conteches.c©m 1 800-338-1 122 www.ContechES.com 1 C 2018 Contech Engineered Solutions LLC,o QUiKRETE Company ALL RIGHTS RESERVED.PRINTED IN THE USA.
