	'''Compost Filter Socks''' consist of compost filter media (compost, or non-treated wood) encased within a three-dimensional fabric tube for purposes of erosion, sediment and pollution control. Compost filter socks are typically used for perimeter protection and are an acceptable alternative to geotextile and other silt fence applications described in [[#806.8.6.4.4 Silt Fence (MO Specifications Sec 624 and 1011)\|EPG 806.8.6.4.4 Silt Fence]]. Compost filter socks are also acceptable alternate ditch checks as described in [[#806.8.6.4.3 Ditch Checks\|EPG 806.8.6.4.3 Ditch Checks]]. Specified effective height, as measured in the field, shall apply for both silt fence and ditch check applications. Compost filter socks shall be installed according to the manufacturer’s specifications or [https://www.modot.org/media/16839 Standard Plan 806.10], including ground preparation and staking requirements. Though compost filter socks are commonly used for perimeter protection and alternate ditch checks, other uses may include: curb and drain inlet protection; slope interruption; protection along the toe of stream and channel banks; on compacted and frozen soils, or pavement where trenching is difficult or impossible; and around sensitive resources where trenching may disturb the resource.

Compost filter socks are also acceptable alternate ditch checks as described in [[#806.8.6.4.3 Ditch Checks\|EPG 806.8.6.4.3 Ditch Checks]].

	Sediment shall be removed once it has accumulated to one-half the original height of the sock. Compost filter sock shall be replaced whenever it has deteriorated to such an extent that the effectiveness of sock is reduced. Compost filter socks shall remain in place until disturbed areas draining to the devices have been permanently stabilized in accordance with the permit. Upon removal of compost filter socks, the wooden stakes should be pulled and the biodegradable netting cut to encourage more rapid degradation. If the netting is non-biodegradable, the netting shall be cut and removed along with the stakes, but the compost filling may be left to further decompose and act as a soil amendment.

	Temporary seeding and mulching is used to produce a quick ground cover of annual grasses to reduce erosion.. It should be used as necessary to prevent erosion and decrease reliance on costly maintenance of sediment control BMPs. For project planning purposes, it is important to understand that temporary vegetative cover will begin to lose its effectiveness within 6 to 12 months depending on site conditions. Separate pay items for Temporary Seeding and for Mulching shall be provided in all projects that include either or both of the following:		Temporary seeding and mulching is used to produce a quick ground cover of annual grasses to reduce erosion..

For project planning purposes, it is important to understand that temporary vegetative cover will begin to lose its effectiveness within 6 to 12 months depending on site conditions. Separate pay items for Temporary Seeding and for Mulching shall be provided in all projects that include either or both of the following:

			:* Warm Season Seeding of areas that will be finish graded prior to Oct. 15 (for most projects, this is 100% of the areas to be seeded with warm season grasses).
	1. Warm Season Seeding of areas that will be finish graded prior to Oct. 15 (for most projects, this is 100% of the areas to be seeded with warm season grasses).		:* Staged construction that requires an area to be graded and then re-graded later (e.g. temporary by-passes, temporary slopes, etc.).

	2. Staged construction that requires an area to be graded and then re-graded later (e.g. temporary by-passes, temporary slopes, etc.).


	Disturbed areas shall be seeded and mulched when and where necessary to eliminate erosion or establish temporary stabilization in areas for warm season grasses when outside the planting season. In designated areas, seeding and mulching shall begin no later than 7 days after earthwork operations have ceased and shall be completed within 14 days (7 days on slopes steeper than 3:1 or greater than 3% and longer than 150 feet), weather permitting. Projects planned over multiple years shall stabilize disturbed areas, with the exception of the road grade itself, during the fall to prevent erosion. If final grade has been achieved, this operation should consist of establishing permanent vegetation in areas where planting is in season.

If final grade has been achieved, this operation should consist of establishing permanent vegetation in areas where planting is in season.

	In general, a quantity of Temporary Seeding should be provided for 100% of areas that will be seeded with Warm Season grasses. This is necessary because, per Sec 805.3.1.2, warm season grass seeding is restricted to the period from Oct. 15 through April 15, and the SWPPP disallows postponement of seed/mulch following grading (see above). If the project includes special provisions that requires any warm-season grass areas to be graded after Oct. 15, but prior to Spring, then those areas can be excluded from Temporary Seeding. Any quantity of Temporary Seeding needed for temporary staged construction, as defined above, should also be provided. A quantity for Mulching should also be provided for all areas of Temporary Seeding. Warm season grass areas that are temporarily seeded and subsequently overseeded after Oct. 15 do not require a second application of mulching.		=====806.8.6.3.7.2 Permanent Seeding and Mulching (MO Specifications [http://www.modot.org/business/standards_and_specs/SpecbookEPG.pdf#page=12 Sec 805] and [http://www.modot.org/business/standards_and_specs/SpecbookEPG.pdf#page=12 Sec 802])=====

	Temporary Seeding is not required for areas that are designated to receive Cool Season grass seeding. Per Sec 805.3.1.1, either full or partial cool season seeding is required immediately following grading, regardless of the season. Overseeding of cool season seeded areas may also be required depending on when the original seeding occurred (see Sec 805.3.1.1 for overseeding requirements).

	Permanent seeding and mulching following the temporary seeding will be performed. It is important to remember that temporary seeding and mulching can be used to cover up bare soil during times that are not conducive to applying permanent seeding. Then, when conditions are more suitable for permanent seeding, it can be applied over/through the temporary seeding stubble.

Inspections will commence once land disturbance operations begin for all projects permitted by and required to comply with MoDOT’s state operating permit for land disturbance. For projects not designed to exceed one acre or are part of a common plan, if operations cause the disturbed acres to exceed one acre or more, inspections will begin once it is known the disturbance will equal one acre or more. If allowable due to right-of-way constraints, receiving streams shall be inspected for off-site sediment deposits for 50 ft. downstream of project outfalls. Inspections are only required to be conducted during the projects normal working hours.

	A typical MoDOT project involves the implementation of many documents, processes, and standard operating procedures. These various processes and procedures are of such detail that it is impossible to include in this brief summary of BMPs. Pollution from storm water can be reduced by the implementation of the BMPs, construction techniques and site management measures in this article. However, pollution from storm water will also be reduced by the issuance of change orders, letters/memos of notification, Order Records, and Contractor Performance Reports. Changes that occur as a result of directives to contractors will usually be documented by Document Records and other various products and reports produced by the computer program, ~~[http://wwwi/intranet/cm/siteManager.htm SiteManager] or AASHTOWare~~. Lastly, a Semi-Final Inspection Report can serve to identify post-construction measures that will ensure permit compliance and water quality protection.

Lastly, a Semi-Final Inspection Report can serve to identify post-construction measures that will ensure permit compliance and water quality protection.

	In addition to these contract management tools, MoDOT maintains training videos for storm water compliance as well as mandatory recertification requirements once every 4 years. All inspectors who will be engaged in storm water inspections, as well as all resident engineers and contractor’s water pollution control managers must be certified through the training video program.
