(A) An applicant is responsible for submitting erosion and sediment control plans that meet the requirements of the Frederick or Catoctin SCD, this chapter, Frederick County's Stormwater chapter, the Standards and Specifications, and the Act. The plans shall include sufficient information to evaluate the environmental characteristics of the affected areas, the potential impacts of the proposed grading on water resources, and the effectiveness and acceptability of measures proposed to minimize soil erosion and off-site sedimentation.
(B) At a minimum, applicants shall submit the following information:
(1) A letter of transmittal and/or application;
(2) Name, address, and telephone number of:
(a) The owner of the property where the grading is proposed;
(b) The developer; and
(c) The applicant;
(3) A vicinity map indicating north arrow, scale, site location, and other information necessary to easily locate the property;
(4) Drainage area map(s) at a 1" = 200' minimum scale showing existing, interim, and proposed topography, proposed improvements, standard symbols for proposed sediment control features, and pertinent drainage information including provisions to protect downstream areas from erosion for a minimum of 200 feet downstream or to the next conveyance system;
(5) The location of natural resources, wetlands, floodplains, highly erodible soils, slopes 15 percent and steeper, and any other sensitive areas;
(6) A general description of the predominant soil types on the site, as described by the appropriate soil survey information available through the local soil conservation district or the USDA Natural Resources Soil Conservation Service;
(7) Proposed stormwater management practices;
(8) Erosion and sediment control plans including:
(a) The existing topography and improvements as well as proposed topography and improvements at a scale between 1" = 10' and 1"= 50' with 2 foot contours or other approved contour interval. For projects with more than minor grading, interim contours may also be required;
(b) Scale, project and sheet title, and north arrow on each plan sheet;
(c) The limit of disturbance (LOD) including:
(i) Limit of grading (grading units, if applicable); and
(ii) Initial, interim, and final phases;
(d) The proposed grading and earth disturbance including:
(i) Total disturbed area;
(ii) Volume of cut and fill quantities; and
(iii) Volume of borrow and spoil quantities;
(e) Storm drainage features, including:
(i) Existing and proposed bridges, storm drains, culverts, outfalls, etc.;
(ii) Velocities and peak flow rates at outfalls for the 2-year and 10-year frequency storm events; and
(iii) Site conditions around points of all surface water discharge from the site;
(f) Erosion and sediment control practices to minimize on-site erosion and prevent off-site sedimentation including:
(i) The salvage and reuse of topsoil;
(ii) Phased construction and implementation of grading unit(s) to minimize disturbances, both in extent and duration;
(iii) Location and type of all proposed sediment control practices;
(iv) Design details and data for all erosion and sediment control practices; and
(v) Specifications for temporary and permanent stabilization measures including, at a minimum:
1. The "Standard Stabilization Note" on the plan stating: "Following initial soil disturbance or re-disturbance, permanent or temporary stabilization must be completed within:
a. Three (3) calendar days as to the surface of all perimeter dikes, swales, ditches, perimeter slopes, and all slopes steeper than 3 horizontal to 1 vertical (3:1); and
b. Seven (7) calendar days as to all other disturbed or graded areas on the project site not under active grading."
2. Details for areas requiring accelerated stabilization; and
3. Maintenance requirements as defined in the Standards and Specifications;
(g) A sequence of construction describing the relationship between the implementation and maintenance of controls, including permanent and temporary stabilization, and the various stages or phases of earth disturbance and construction. Any changes or revisions to the sequence of construction must be approved by the Frederick or Catoctin SCD prior to proceeding with construction. The sequence of construction, at a minimum, must include the following:
(i) Request for a pre-construction meeting with the appropriate inspection/enforcement authority;
(ii) Clearing and grubbing as necessary for the installation of perimeter controls;
(iii) Construction and stabilization of perimeter controls;
(iv) Remaining clearing and grubbing within installed perimeter controls;
(v) Road grading;
(vi) Grading for the remainder of the site;
(vii) Utility installation and connections to existing structures;
(viii) Construction of buildings, roads, and other construction;
(ix) Final grading, landscaping, and stabilization;
(x) Installation of stormwater management measures;
(xi) Approval of the appropriate inspection/enforcement authority prior to removal of sediment controls; and
(xii) Removal of controls and stabilization of areas that are disturbed by removal of sediment controls.
(h) A statement requiring the owner/developer or representative to contact the Frederick County Department of Permits and Inspections or its agent at the following stages of the project or in accordance with the approved erosion and sediment control plan, grading permit, or building permit:
(i) Prior to the start of earth disturbance;
(ii) Upon completion of the installation of perimeter erosion and sediment controls, but before proceeding with any other earth disturbance or grading;
(iii) Prior to the start of another phase of construction or opening of another grading unit; and
(iv) Prior to the removal of sediment control practices;
(i) Certification by the owner/developer that any clearing, grading, construction, or development will be done pursuant to the approved erosion and sediment control plan. The certification must also require that the responsible personnel involved in the construction project have a Certificate of Training at an MDE approved training program for the control of erosion and sediment prior to beginning the project. The Certificate of Training for Responsible Personnel may be waived by the Frederick or Catoctin SCD on any project involving four or fewer residential lots. Additionally, the owner/developer shall allow right of entry for periodic on-site evaluation by the Frederick or Catoctin SCD, Frederick County Department of Permits and Inspections, and/or MDE; and
(j) Certification by a professional engineer, land surveyor, landscape architect, architect, or forester (for forest harvest operations only) registered in the State that the plans have been designed in accordance with erosion and sediment control laws, regulations, and standards, if required by the Frederick or Catoctin SCD or the Administration.
(9) Any additional information or data deemed appropriate by the Frederick or Catoctin SCD.
