§ 169-5 Design criteria, standards and specifications for control measures.

All control measures required to comply with this chapter shall meet the design criteria, standards and specifications identified by the Village of Randolph.

§ 169-6 Maintenance of control measures.

All sedimentation basins and other control measures necessary to meet the requirements of this chapter shall be maintained by the applicant or subsequent landowner during the period of land disturbance and land development of the site in a satisfactory manner to ensure adequate performance and to prevent nuisance conditions.

§ 169-7 Erosion control requirements.

A. 
Applicability. This section applies to the following sites of land developing or land disturbing activities:[1]
(1) 
Those lands over five acres in area requiring a subdivision plat approval;
(2) 
Commercial, industrial or institutional buildings on lots of five acres or more;
(3) 
Those projects of 100 linear feet or more involving street, highway, road, or bridge construction, enlargement, relocation, or reconstruction; or
(4) 
Those projects involving the laying, repairing, replacing, or enlarging of an underground pipe or facility for a distance of 100 feet or more.

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
B. 
Erosion and other pollutant control requirements. The following requirements shall be met on all sites described in Subsection A:
(1) 
Site dewatering. Water pumped from the site shall be treated by temporary sedimentation basins, grit chambers, sand filters, upflow chambers, hydrocyclones, swirl concentrators, or other appropriate controls designed and used to remove particles of 100 microns or greater for the highest dewatering pumping rate. If the water is demonstrated to have no particles greater than 100 microns during dewatering operations, then no control is needed before discharge, except as determined by the Village of Randolph. Water may not be discharged in a manner that causes erosion of the site or receiving channels.
[NOTE: There are many ways to meet this particle size performance objective, depending on the pumping rate. As an example, if the pumping rate is very low (one gallon per minute), then an inclined or vertical enlarged pipe (about eight inches in diameter for one gallon per minute) several feet long would be an adequate control device to restrict the discharge of one-hundred-micron and larger particles. As the pumping rate increases, then the device must be enlarged. At a moderate (100 gallons per minute) pumping rate, a vertical section of corrugated steel pipe, or concrete pipe section, or other small tank (about 4 1/2 feet across for a pumping rate of 100 gallons per minute) several feet tall would be adequate. With these pipe sections or small tanks, inlet baffles would be needed to minimize turbulence. With very large pumping rates (10,000 gallons per minute), sediment basins (about 35 feet in diameter for a pumping rate of 10,000 gallons per minute) at least three feet in depth with a simple (but adequately sized) pipe outlet would be needed. More sophisticated control devices (such as swirl concentrators or hydrocyclones) could be specially fabricated that would generally be smaller than the simple sedimentation devices described above, but they would not be required.
The performance standard of one-hundred-micron maximum particles in the dewatering water at the maximum pumping rate significantly reduces the liability of the contractor when compared to a standard of "no visible particulate matter." If a properly sized device is correctly used, based on the one-hundred-micron particle size performance standard, then discharges of visible particulate matter would not constitute a violation. It is not possible to design a control device that would ensure "no visible particulate matter" discharges. This one-hundred-micron standard is intended to significantly reduce sedimentation problems in downstream drainage systems and in the receiving waters that are caused by large particles. Visible particulate matter will probably still occur in water meeting this standard, as most turbidity effects are caused by very small particles that usually do not cause as severe of a sedimentation problem as larger particles. This one-hundred-micron particle size performance standard was therefore selected to be easily met and enforced and to reduce sedimentation problems. A "no visible particulate matter" standard in contrast could not be met easily or cheaply, violations would frequently occur, and inspectors would have to make frequent site visits and require frequent control device changes. In addition, particle size measurements would not be required to prove compliance with the one-hundred-micron performance standard. Only the proper use of a device designed to meet this particle size criteria is needed. However, if a contractor or site engineer feels that the dewatering water does not contain any particles larger than 100 microns, no control device would be needed if optional frequent particle size analyses confirm that fact. In most cases, the use of the simple control devices described previously would be less expensive and less bothersome than performing frequent particle size analyses.]
(2) 
Waste and material disposal. All waste and unused building materials (including garbage, debris, cleaning wastes, wastewater, toxic materials, or hazardous materials) shall be properly disposed and not allowed to be carried by runoff into a receiving channel or storm sewer system.
(3) 
Tracking. Each site shall have graveled roads, access drives and parking areas of sufficient width and length to prevent sediment from being tracked onto public or private roadways. Any sediment reaching a public or private road shall be removed by street cleaning (not flushing) before the end of each workday.
(4) 
Drain inlet protection. All storm drain inlets shall be protected with a straw bale, filter fabric, or equivalent barrier meeting accepted design criteria, standards and specifications.
(5) 
Site erosion control. The following criteria [Subsection B(5)(a) through (d)] apply only to land developing or land disturbing activities that result in runoff leaving the site:[2]
(a) 
Channelized runoff from adjacent areas passing through the site shall be diverted around disturbed areas, if practical. Otherwise, the channel shall be protected as described below in Subsection B(5)(c). Sheet flow runoff from adjacent areas greater than 10,000 square feet in area shall also be diverted around disturbed areas, unless shown to have resultant runoff velocities of less than 0.5 foot per second across the disturbed area for the set of one-year design storms. Diverted runoff shall be conveyed in a manner that will not erode the conveyance and receiving channels. (NOTE: Natural Resources Conservation Service guidelines for allowable velocities in different types of channels should be followed.)
(b) 
All activities on the site shall be conducted in a logical sequence to minimize the area of bare soil exposed at any one time.
(c) 
Runoff from the entire disturbed area on the site shall be controlled by meeting the following criteria:
[1] 
For sites of less than 10 acres disturbed at one time, filter fences, straw bales, or equivalent control measures shall be placed along all side slope and down slope sides of the site. If a channel or area of concentrated runoff passes through the site, filter fences shall be placed along the channel edges to reduce sediment reaching the channel.
[2] 
For sites with more than 10 acres disturbed at one time, or if a channel originates in the disturbed area, one or more sedimentation basins shall be constructed. Each sedimentation basin shall have a surface area of at least 1% of the area draining to the basin and at least three feet of depth and shall be constructed in accordance with accepted design specifications. Sediment shall be removed to maintain a depth of three feet. The basin shall be designed to trap sediment greater than 15 microns in size, based on the set of one-year design storms having durations from 0.5 to 24 hours. The basin discharge rate shall also be sufficiently low as to not cause erosion along the discharge channel or the receiving water.
(d) 
Any soil or dirt storage piles containing more than 10 cubic yards of material should not be located with a down slope drainage length of less than 15 feet to a roadway or drainage channel.
(e) 
In-street utility repair or construction soil or dirt storage, for applicable project sites, must be protected with straw bale or other appropriate filtering barriers to prevent down-site erosion.
