§ 170.05 EROSION AND SEDIMENT CONTROL STANDARDS.

   (A)   The following soil erosion and sediment control-related requirements shall be met for all regulated land disturbing activities as defined in § 170.04 of this chapter:
      (1)   All erosion control measures, construction and post construction storm water runoff shall meet the current minimum departmental and Illinois EPA standards and requirements at the time of installation.
      (2)   Construction site operators shall control or prohibit non-storm water discharges from any site. This includes concrete and wastewater from washout of concrete (unless managed by an appropriate control), drywall compound, wastewater from washout and cleanout of stucco, paint, form release oils, curing compounds and other construction materials, fuels, oils, or other pollutants used in vehicle and equipment operation and maintenance, soaps, solvents, or detergents, toxic or hazardous substances from a spill or other release, or any other pollutant that could cause or tend to cause water pollution.
      (3)   Erosion control measures must be in place and approved prior to all land disturbances.
      (4)   Soil disturbance shall be conducted in such a manner as to minimize erosion. Areas of the development site that are not to be graded shall be protected from construction traffic or other disturbance until final seeding is performed. Soil stabilization measures shall consider the time of year, site conditions, and the use of temporary or permanent measures.
      (5)   Properties and channels adjoining development sites shall be protected from erosion and sedimentation. At points where concentrated flow leaves a development site, energy dissipation devices shall be placed at discharge locations and along the length of any outfall channel as necessary to provide a non-erosive velocity of flow from the structure to the watercourse so that the natural physical and biological characteristics and functions are maintained and protected.
      (6)   Soil erosion and sediment control features shall be constructed prior to the commencement of hydrologic disturbance of upland areas.
      (7)   Disturbed areas shall be stabilized with temporary or permanent measures within 14 calendar days following the end of active hydrologic disturbance, or redisturbance, consistent with the following criteria or using an appropriate measure as approved by the Administrator.
         (a)   Appropriate temporary or permanent stabilization measures shall include seeding, mulching, sodding, and/or non-vegetative measures.
         (b)   Areas of embankments having slopes greater than or equal to 3H:1V shall be stabilized with staked-in-place sod,,mat, or blanket in combination with seeding.
         (c)   Erosion control blankets shall be required on all interior detention basin side slopes between the normal water level and high water level.
         (d)   The 14-day stabilization requirement may be precluded by snow cover or where construction activity will resume within 21 days from when the active hydrologic disturbance ceased, then stabilization measures do not have to be initiated on that portion of the site by the fourteenth day after construction activity temporarily ceased, given that portion of the site has appropriate soil erosion and sediment controls.
      (8)   Land disturbance activities in streams shall be avoided, where possible. If disturbance activities are unavoidable, the following requirements shall be met:
         (a)   Where stream construction crossings are necessary, temporary crossings shall be constructed of non-erosive material.
         (b)   The time and area of disturbance of a stream shall be kept to a minimum. The stream, including bed and banks, shall be restabilized within 48 hours after channel disturbance is completed or interrupted.
         (c)   Any applicable federal and state permits that have been approved shall be provided to the Administrator.
      (9)   Soil erosion and sediment control measures shall be appropriate with regard to the amount of tributary drainage area as follows:
         (a)   Disturbed areas draining less than one acre shall, at a minimum, be protected by a filter barrier (including filter fences, which at a minimum, meet the applicable sections of the AASHTO Standard Specification 288-00, or equivalent control measures) to control all off-site runoff. Vegetated filter strips, with a minimum width of 25-feet, in the direction of flow, may be used as an alternative only where runoff in sheet flow is expected.
         (b)   Disturbed areas draining more than one but fewer than five acres shall, at a minimum, be protected by a sediment trap or equivalent control measure at a point downslope of the disturbed area.
         (c)   Disturbed areas draining five acres or more, shall, at a minimum, be protected by a sediment basin with a perforated filtered riser pipe or equivalent control measures at a point downslope of the disturbed area.
         (d)   Sediment basins shall have both a permanent pool (dead storage) and additional volume (live storage) with each volume equal to the runoff amount of a two-year, 24-hour event over the onsite hydrologically disturbed tributary drainage area to the sediment basin. The available sediment volume below normal water level, in addition to the dead storage volume shall be sized to store the estimated sediment load generated from the site over the duration of the construction period. For construction periods exceeding one year, the one-year sediment load and a sediment removal schedule may be submitted. If the detention basin for the proposed development condition of the site is used for the sediment basin, the above volume requirements will be explicitly met. Until the site is finally stabilized, the basin permanent pool of water shall meet the above volume requirements and have a filtered perforated riser protecting the outflow pipe.
         (e)   To calculate the sediment load, applicants can use FLOWSED as developed by the USEPA and other design guidelines by USEPA.
      (10)   All storm sewers that are or will be functioning during construction shall be protected by an appropriate sediment control measure and cleaned at any point during construction as needed and once the site has been stabilized.
      (11)   If dewatering services are used, adjoining properties and discharge locations shall be protected from erosion. Discharges shall be routed through an effective sediment control measure (e.g., sediment trap, sediment basin, or other appropriate measures).
      (12)   All temporary soil erosion and sediment control measures shall be removed within 30 days after final site stabilization is achieved or after the temporary measures are no longer needed. Trapped sediment and other disturbed soil areas, including areas disturbed while removing temporary measures, shall be permanently stabilized.
      (13)   A stabilized construction entrance, consisting of a stabilized mat of sufficiently sized aggregate underlain with filter cloth (or other appropriate measures) shall be located at any point where traffic will be entering or leaving a construction site of a major development to or from a public right-of-way, street, alley, or parking area. Any sediment or soil reaching an improved public right-of-way, street, alley, or parking area shall be removed by scraping or street cleaning. Sediment or soil shall at a minimum, be removed daily and more frequently as accumulations warrant. Removed sediment or soil shall be transported to a controlled sediment disposal area. The Administrator may require additional stabilized construction entrance methods.
      (14)   Earthen embankments shall be constructed with side slopes no steeper than 3H:1V. Steeper slopes may be constructed with appropriate stabilization as approved by the Administrator.
      (15)   Stormwater conveyance channels, including ditches, swales, and diversions, and the outlet of all channels and pipes shall be designed and constructed to withstand the expected flow velocity from the ten-year frequency storm without erosion. All constructed or modified channels shall be stabilized within 48 hours.
      (16)   Temporary diversions shall be constructed, as necessary, to direct all runoff from hydrologically disturbed areas to the appropriate sediment trap or basin.
      (17)   Soil stockpiles shall not be located in a flood-prone area or a designated buffer protecting Waters of the United States. Soil stockpiles are defined as having greater than 50 cubic yards of soil and will remain in place for more than seven days. Soil stockpile locations shall be shown on the soil erosion and sediment control plan and shall have the appropriate measures to prevent erosion of the stockpile.
      (18)   Handbooks: Standards and specifications contained in the Illinois Urban Manual, as amended, and the planning procedures sections of the Illinois Procedures and Standards for Urban Soil Erosion and Sedimentation Control, as amended, are referenced in this ordinance as guidance for presenting soil erosion and sediment control plan specifications and delineating procedures and methods of operation under site development for soil erosion and sediment control. In the event of conflict between provisions of said manuals and this chapter, this chapter shall govern.
      (19)   The applicant shall provide adequate receptacles for the deposition of all construction material debris generated during the development process. The applicant shall not cause or permit the dumping, depositing, dropping, throwing, discarding, or leaving of construction material debris upon or into any development site, channel, or Waters of the U.S. The applicant shall maintain the development site free of construction material debris.
      (20)   All regulated construction sites shall have a SWPPP that meets the requirements of Part IV of NPDES Permit No. ILR10.

§ 170.10 NOTIFICATIONS.

   To facilitate inspections by the Administrator and to ensure compliance with the approved erosion and sediment control plan, the grading or building permit, and this chapter, the permittee shall notify the Administrator within one to three working days of the completion of the construction stages specified below:
   (A)   For Class 1 land disturbance permits:
      (1)   Upon completion of installation of sediment and runoff control (controls and diversions), prior to proceeding with any other earth disturbance or grading;
      (2)   After stripping and clearing;
      (3)   After rough grading;
      (4)   After final grading;
      (5)   After seeding and landscaping deadlines; and
      (6)   After final stabilization and landscaping, prior to removal of sediment controls.
   (B)   For Class 2 land disturbance permits only items (1), (3), and (6) in the above division (A) shall apply.
   (C)   If stripping, clearing, grading, and/or landscaping are to be done in phases or separate areas, the permittee shall give notice at the completion of each of the above work stages in each phase or area.
   (D)   Special precautions.
      (1)   If at any stage of the grading of any development site the Administrator determines by inspection that the nature of the site is such that further work authorized by an existing permit is likely to imperil any property, public way, stream, lake, wetland, or drainage structure, the Administrator may require, as a condition of allowing the work to be done, that such reasonable special precautions be taken as is considered advisable to avoid the likelihood of such peril. “Special precautions” may include, but shall not be limited to, a more level exposed slope, construction of additional drainage facilities, berms, terracing, compaction, or cribbing, installation of plant materials for erosion control, and
      (2)   Recommendations of a soil scientist and/or engineering geologist, which may outline requirements for further work.
      (3)   Where it appears that storm damage may occur due to incomplete grading at the site, work may be stopped and the permittee required to install temporary structures or take such other measures as may be required to protect adjoining property or the public safety. On large developments or where unusual site conditions prevail, the Administrator may specify the start and end dates for grading operations or may require that the operations be conducted in specific stages so as to ensure completion of protective measures or devices prior to the advent of seasonal rains.

§ 170.11 VARIANCES AND APPEALS.

   (A)   The Administrator upon application, and subject to the process and standards that follow, may grant variances to the provisions of this chapter as will not cause detriment to the public good, safety, or welfare nor be contrary to the spirit, purpose, and intent of this chapter where, by reason of unique and exceptional physical circumstances or condition of a particular property, the literal enforcement of the provisions of this chapter would result in an unreasonable hardship.
   (B)   Any person wishing to appeal, or seeking a variance in, a determination made by the Administrator under the provisions of this chapter may do so to the Board of Appeals by following the procedures set forth in § 164.13 of this Code of Ordinances. Failure to file said appeal within the required time shall preclude further review. The appeal must state specifically:
      (1)   The determination made by the Administrator that is being appealed;
      (2)   The basis for the appeal;
      (3)   The position of the party appealing;
      (4)   Any supportive information for the position of the party appealing; and
      (5)   Such additional information as the party may wish to submit.
   (C)   Any person aggrieved by a decision, requirements, ruling, or interpretation of this chapter by the Administrator may appeal it to the municipality by written notice filed with the Zoning Board of Appeals within ten days of the determination.

§ 170.12 DISCLAIMER OF LIABILITY.

   It is recognized that the degree of erosion and sediment control required by this chapter is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. However, on occasion, greater rain amounts will occur and will result in greater erosion and sediment producing activity. These provisions shall not create liability on the part of the City of Danville nor any officer or employee thereof for any damages that result from reliance on this chapter or any administrative decision lawfully made thereunder.
(Ord. 9098, passed 5-16-17)

§ 170.13 SEVERABILITY.

   If any section, clause, provision, or portion of this chapter is judged unconstitutional or invalid by a court of competent jurisdiction, the remainder of this chapter shall remain in force and not be affected by such judgment.
(Ord. 9098, passed 5-16-17)

§ 170.99 PENALTY.

   (A)   Any person or owner determined by the Administrator, or a court having jurisdiction, to be in violation of any of the provisions of this chapter, except as required or mandated by any state and/or federal agency having concurrent or superior regulatory jurisdiction, shall be fined not less than $100 and not more than $1,000 for each violation. Each day the violation continues shall be deemed a separate offense.

      (1)   The Administrator may require that all work on a site which is being performed contrary to the provisions of this article or is being performed in an unsafe or dangerous manner, shall be immediately stopped. Stop-work orders do not include work related to the installation or maintenance of erosion control devices that are a part of bringing the site back into compliance under this chapter. The Administrator may issue a stop-work order for the entire project or any specified part thereof if any of the following conditions exist:
         (a)   Any land disturbance activity regulated under this chapter is being undertaken without a permit.

In addition, a copy of the stop-work order may be given to any person in charge of or performing work on drainage improvements in the development, or to an agent of any of the foregoing. The stop-work order shall state the conditions under which work may be resumed. No person shall continue any work after having been served with a stop-work order, except such work as is directed to be performed to remove a violation or dangerous or unsafe condition, as provided in the order.
      (3)   For the purposes of this section, a stop-work order is validly posted by posting a copy of the stop-work order on the site of the land disturbing activity in reasonable proximity to a location where the land disturbing activity is taking place. A copy of the order, in the case of work for which there is a permit, shall be mailed by first class mail, postage prepaid, to the address listed by the permittee on the permit. In the case of work for which there is no permit, a copy of the order shall be mailed to the person to whom real estate taxes are assessed, or if none, to the taxpayer shown by the records of the county assessor.
      (4)   If the permittee does not immediately cease land disturbance activity upon posting of the stop-work order or comply with the erosion and sediment control plan or permit conditions within one day, the City Engineer may revoke the permit.
      (5)   If the owner or land user where no permit has been issued does not cease the land disturbance activity, the City Engineer may request the City Attorney to obtain injunctive relief.
      (6)   The Administrator may retract the revocation.
      (7)   Ten days after posting a stop-work order, the Administrator may issue a notice to the owner and permittee of the Administrator’s intent to perform the work necessary to prevent erosion and institute sediment control. The Administrator may go on the land and commence work after 14 days from issuing the notice. The costs incurred by the Administrator to perform this work shall be paid by the owner or permittee. In the event no permit was issued, the costs, plus a reasonable administrative fee, shall be billed to the owner.
      (8)   Compliance with the provisions of this chapter may also be enforced by injunction.
      (9)   If at any time conditions of the site warrant emergency actions the Administrator shall be allowed to respond appropriately to prevent harm to public safety, harm to public health, or damage to property.
   (E)   Enforcement of notice of violation and stop-work orders.
      (1)   A complaint may be filed with the circuit court for any violation of this chapter. A separate violation shall be deemed to have been committed on each day that the violation existed.
      (2)   In addition to other remedies, the City Attorney may institute any action or proceeding which:
         (a)   Prevents the unlawful construction, alteration, repair, maintenance, or removal of drainage improvements in violation of this chapter or the violation of any permit issued under the provisions of this chapter;
         (b)   Prevents the occupancy of a building, structure, or land where such violation exists;
         (c)   Prevents any illegal act, conduct, business, or use in or about the land where such violation exists;
         (d)   Restrains, corrects, or abates the violation.
      (3)   In any action or proceeding under this section, the City Attorney may request the court to issue a restraining order or preliminary injunction, as well as a permanent injunction, upon such terms and conditions as will enforce the provisions of this chapter. A lien may also be placed on the property in the amount of the cleanup costs.
