3 Specifications for Using Filtrexx Growth Media Blankets Filtrexx Growth Media Blanket Installation and Maintenance 1.0 Description: This work shall consist of furnishing, installing, maintaining and seeding a water permeable Growth Media Blanket (Filtrexx Growth Media Blanket) to reduce soil erosion and sediment by preventing soil particles from water moving off site into adjacent waterways or storm water drainage systems. 2.0 Growth Media Products 1. Growth Media used for Filtrexx Growth Media Blankets shall be weed free and derived from a well-decomposed source of organic matter. The media shall be produced using an aerobic composting process meeting or exceeding M.O.E. 101, C.C.M.E. Type A and Type AA regulations, and Compost Quality Assurance Program,(C.Q.A.) including time and temperature data indicating effective weed seed, pathogen and insect larvae kill. The growth media shall be free of any refuse, contaminants or other materials toxic to plant growth. Noncomposted products will not be accepted. Test methods for the items below should follow USCC TMECC guidelines for laboratory procedures: A. PH in accordance with TMECC A, Electrometric ph Determinations for Compost B. Non seeded Filtrexx Growth Media Blankets: Particle size 100% passing a 50mm{2 } sieve, 99% passing a 25mm{1 } sieve, minimum of 90% passing a 18.25mm{3/4 } sieve in accordance with TMECC B, Sample Sieving for Aggregate Size Classification. For seeded Growth Media Blankets, seed should be incorporated at the time of application in the entire depth of the growth media blanket, at rates per square foot, per square yard, per square meter, per acre or per hectare, as acceptable to the engineer. The following particle sizes shall also be followed: 100% passing a 50mm{2 } sieve, 99% passing a 25mm{1 } sieve, minimum of 60% passing a 12.5mm{1/2 }sieve. All other testing parameters remain the same. The seeding rates are generally similar or slightly higher than those used when considering application of seed via hydroseeding or other seeding methods. C. Moisture content of less than 60% in accordance with standardized test methods for moisture determination. D. Material shall be relatively free (<1% by dry weight) of inert or foreign man made materials. E. A sample shall be submitted to the engineer for approval prior to being used and must comply with all local, provincial and federal regulations. 3

4 3.0 Construction: 1. Filtrexx Growth Media Blankets will be placed at locations indicated on plans as directed by the Engineer. Unless otherwise specified, Filtrexx Growth Media Blankets should be installed at a minimum depth of 25mm {1 }. Depth requirements are indicated on CAD drawings attached. 2. Filtrexx Growth Media Blankets may be seeded at time of installation for establishment of permanent vegetation. The Engineer will specify seed requirements. 3. Filtrexx Growth Media Blankets are not to be used in direct flow situations or in runoff channels. 4. See attached schematic for Growth Media Blanket Installation. 5. If required, combining Filtrexx Growth Media Blankets with Filtrexx SiltSoxx or Filter Berms may offer additional protection from slopes that have heavy run-on water. In these situations, Filtrexx SiltSoxx, Filter Berms and Growth Media Blankets may be used in combination (see schematic attached). TM TM 4.0 Maintenance: 1. The contractor shall maintain the Filtrexx Growth Media Blanket in a functional condition at all times and it shall be routinely inspected. 2. If the Growth Media Blanket fails, it will be routinely repaired. 3. The Filtrexx Growth Media Blanket will be seeded on site, at rates and seed types as determined by the Engineer. Once vegetation is established, final seeding is not required. 4

5 5.0 Method of measurement: Bid items shall show measurement as Filtrexx Growth Media Blanket per square foot, per square yard, or per square meter. Depth to be measured at time of application. 6.0 Performance: 1. Contractor is responsible for establishing a working erosion control system and may, with approval of the Engineer, work outside the minimum construction requirements as needed. 2. If the Filtrexx Growth Media Blanket deteriorates or fails, it will be repaired or replaced. 7.0 Application guidelines: 1. Contractor shall provide the Engineer with proof that ie: a 50mm{2 } Growth Media Blanket has been applied. This rate equals approximately 270 cubic yards of compost material per acre of application area or approximately 665 cubic yards per hectare. Contractor will supply ample evidence showing this amount of material has been effectively placed (i.e., truck load tickets). 2. Contractor is required to be a certified Filtrexx Installer as determined by Filtrexx Canada Inc.
