Illicit Discharge Compliance Statement

Transcription

1 Illicit Discharge Compliance Statement Responsibility: The Owner is responsible for ultimate compliance with all provisions of the Massachusetts Stormwater Management Policy, the USEPA NPDES Construction General Permit and responsible for identifying and eliminating illicit discharges (as defined by the USEPA). OWNER NAME: Northeast Foods, LLC ADDRESS: 4415 Highway 6 Sugarland, TX TEL. NUMBER: Engineer s Compliance Statement: To the best of my knowledge, the attached plans, computations and specifications meet the requirements of Standard 10 of the Massachusetts Stormwater Handbook regarding illicit discharges to the stormwater management system and that no detectable illicit discharges exist on the site. All documents and attachments were prepared under my direction and qualified personnel properly gathered and evaluated the information submitted, to the best of my knowledge. Included with this statement are site plans, drawn to scale, that identify the location of systems for conveying stormwater on the site and show that these systems do not allow the entry of any illicit discharges into the stormwater management system. The plans also show any systems for conveying wastewater and/or groundwater on the site and show that there are no connections between the stormwater and wastewater systems. For a redevelopment project (if applicable), all actions taken to identify and remove illicit discharges, including without limitation, visual screening, dye or smoke testing, and the removal of any sources of illicit discharges to the stormwater management system are documented and included with this statement.

2 ULTRATECH INTERNATIONAL, INC. How To Use The Ultra-Drain Seal Protective cover for drains, grates and manholes against accidental spills. Follow these easy steps to assure maximum effectiveness: 1. Make sure the Ultra-Drain Seal is the correct size. For best results, use a Ultra-Drain Seal which is 6 larger than the outside of the grate. 2. Apply the Ultra-Drain Seal. A. R emove all stones, branches, or other debris off the object you desire to cover. B. R emove the plastic film from the Ultra-Drain Seal and remember to keep it to re-apply before storage. C. Place the Ultra-Drain Seal over the drain, grate, or manhole you desire to seal. D. To gain a faster seal you may step on the DrainSealTM. Never attempt this after spill has reached the drain. 3. Always decontaminate the Ultra-Drain Seal before reuse or storage. A. W ash the Ultra-Drain Seal and its plastic film in warm water with a non-abrasive detergent or petroleum solvent cleaner. B. D ry both the Drain Seal and plastic film with a cloth and reapply the plastic film to the Drain Seal. C. U sing the tube provided, roll up the Drain Seal and place it back into the container for storage. D. Store the Ultra-Drain Seal out of direct sunlight, and at room temperature. IMPORTANT NOTES: Never allow the Ultra-Drain Seal to touch itself for long periods of time. The Ultra-Drain Seal will become less flexible if stored in cold temperatures. Due to the nature of softer urethane, the physical properties of these products may change with exposure to certain environmental conditions like temperature, humidity and UV radiation. Please inspect the stored product regularly to ensure it is in a usable state. Not intended for long-term outdoor use (more than two (2) hours), as UV exposure and/or heat for extended periods can degrade the product. For applications where extended use may be required, the Ultra-Drain Seal Plus should be considered. These chemicals are compatible for use with Ultra-Drain Seal : Acetone* Aluminum Salts Ammonia Barlum Salts Benzyl Alcohol Boric Acid Sol. Butane Butanol Calcium Salts Carbon Dioxide Chloroform* Chlorothane VG Copper Salts Cyclohexanone Formaldehyde Freon Gasoline Glycol Ether Hydrochloric Acid (Med. Conc.) Hydrofluoric Acid (Med.

6 VortSentry HS Technical Abstract Removal Characteristics Using F-55 The VortSentry HS The VortSentry HS is a hydrodynamic separator that facilitates the settling of solids and the separation of free oil and grease commonly found in stormwater runoff. The Testing The performance characteristics of the VortSentry HS were assessed under controlled laboratory conditions using F-55, a commercially available sand product. The Conclusion Testing successfully identified the operating characteristics of the VortSentry Model HS48 for flows up to 1.5 cfs and allows the following to be determined: The VortSentry Model HS48 provides removal of solids (d50=240-um) demonstrating >80% removal at flows below 1.2 cfs The VortSentry Model HS48 experiences 1-inch of head loss for every 0.25 cfs of flow up to 2.0 cfs. Head Equalizing Baffle Outlet Pipe Contaminant Tested CONTECH Stormwater Solutions used the commercially available sand product F-55 for laboratory solids removal testing of the VortSentry HS model HS48. Manufactured by U.S. Silica Company as a foundry sand, F-55 is a natural silica sand product (SG=2.65) consisting of round grain sand processed to produce a particle distribution of 100-µm to 600-µm with a d50 of approximately 240-µm. Particle size distribution is shown below. Percent Finer (by mass) Test Apparatus and Operation The VortSentry HS is a hydrodynamic separator which uses swirl-concentrator technology to enhance gravity separation. A typical VortSentry HS configuration as shown at left. The performance evaluation consisted of multiple runoff simulations, with the cleaning and refilling of the slurry tank between each simulation. Each simulation began with predetermined flow rates, and after attaining steady-state flow, slurry was injected at a predetermined rate. Three residence times were allowed, and then samples were taken at one-minute intervals.

7 VortSentry HS Te c h n i c a l A b s t r a c t Removal Characteristics Using F-55 Test Results A total of nine simulations were performed at flow rates between 0.51 and 1.56 cfs. Results are shown in the table below. Removal efficiencies were calculated by averaging the influent and effluent solids concentrations corresponding to a simulation and applying the following standard formula: Removal Efficiency % = ((influent solids conc.) (effluent solids conc.)) / (influent solids conc.) Average Q (cfs) Sample Location Inf. Eff. Inf. Eff. Inf. Eff. Inf. Eff. Inf. Eff. Inf. Eff. Inf. Eff. Inf. Eff. Inf. Eff Average (mg/l) Efficiency 97% 96% 90% 85% 88% 87% 79% 74% 67% The performance curve based upon flow is shown below and demonstrates a gradual decrease in performance as flow increases to approximately 1.5 cfs. Headloss observations indicate that the headloss relationship is reasonably linear, with 1-inch of headloss for every 0.25 cfs of flow up to 2.0 cfs.
