To request an extension a quarry operator must submit a written request 60 days prior to expiration of the special permit. The SPGA, at its discretion, may extend a permit or may require a public hearing on said extension.
H.
Existing quarry operations. A quarry in lawful operation on the date of adoption of § 135-1202 may continue until such time it is abandoned. However, unless specifically authorized by a new special permit:
§135-1203 Erosion control regulations.
[Added 5-7-2003 ATM by Art. 38]
A.
Preamble. Uncontrolled excavation, grading and land disturbance may cause excessive quantities of soil to erode. Erosion, and resulting sediment, requires the costly repair of roads and embankments; creates excess turbidity; clogs storm drains and swales; muddies streams; silts rivers and lakes and limits the use of water for most beneficial purposes. Sediment-choked streams are unsightly, and reduced channel capacity may result in flooding.
B.
Purpose. The purposes of the erosion control regulations are to:
(1)
Reduce damage from sediment and erosion by controlling stormwater runoff (runoff) and by protecting exposed or disturbed areas;
(2)
Protect surface and ground water quality, minimize erosion and reduce flooding by restricting runoff to nonerosive velocities through the use of erosion and runoff control measures (control measures);
(3)
Incorporate control measures into site planning at an early stage in the design process;
(4)
Prevent the unnecessary stripping of vegetation and loss of soils especially adjacent to water bodies;
(5)
Prevent land disturbance that may cause mass movement, slumping or erosion of land surfaces;
(6)
Prevent excess turbidity in water bodies;
(7)
Minimize maintenance and repairs to roads, embankments, swales, streams, water bodies, stormwater control facilities, and adjoining lots;
(8)
Retain appropriate performance guaranties to ensure compliance with permits.
C.
Intent. Section 135-1203 allows broad discretion to address the impacts from land disturbance so long as control measures comply with the objectives and design standards. Section 135-1203 therefore does not specify or mandate specific control measures. They provide the flexibility to choose control measures subject to review by the SPGA. Section 135-1203 is intended to supplement provisions of the Wetlands Protection Act (Act). Where § 135-1203 is less restrictive than the Act, the provisions of the Act shall govern.
D.
Applicability.
(1)
Section 135-1203 shall apply to every land disturbance where:
(a)
Site work involves excavating or filling more than 150 cy of material;
(b)
Site work cumulatively disturbs more than 5,000 square feet;
(c)
Site work will occur on a slope greater than 15%;
(d)
A site contains highly erodible soils;
(e)
A site directly drains into a water body; or
(f)
The SPGA determines that there is a high potential for environmental degradation from erosion or runoff.
E.
Application for erosion control permit. Persons wishing to engage in land disturbance activities shall apply to the SPGA for an erosion control permit in accordance with these regulations and said activities shall not begin unless said permit has been issued.
F.
Erosion and stormwater runoff control plan. Application for an erosion control permit shall be accompanied by an erosion and stormwater control plan and report prepared and stamped by a RPE in accordance with the methods and measures identified in:
"The Massachusetts Erosion and Sediment Control Guidelines for Urban and Suburban Areas: A Guide For Planners, Designers, and Municipal Officials" (EOEA) | ||

G.
Design standards.
(1)
Development shall be fitted to topography and soils so as to minimize erosion.
(2)
Land disturbance activity work shall not begin prior to the starting date specified in the plan.
(3)
Natural vegetation shall be retained and protected wherever possible.
(4)
Clearing, grading or other site work shall be done in a manner that will minimize erosion. Said activities shall be limited to the area required for immediate construction operations and for the shortest practical period of time.
(5)
Site drainage shall be designed to effectively treat increased runoff created during and after construction so that adjoining lots and downstream water bodies are protected from erosion.
(6)
Uncontrolled runoff shall not be diverted onto adjoining lots or into the storm drain or sewer system. Said runoff shall be disposed of at nonerosive velocities at established drainage locations.
(7)
Sediment transported by runoff shall be retained on site through the use of sediment basins, silt traps or other appropriate measures. Said measures shall be installed prior to clearing and grading to the extent practical.
(8)
Cut and fill slopes shall be constructed so as to minimize erosion. Slopes shall not be steeper than two horizontal to one vertical unless approved by the SPGA.
(9)
Diversions or other appropriate measures shall be installed at the top of cut and fill slopes to prevent uncontrolled drainage flows on the disturbed slopes.
(10)
Drainage swales used to divert runoff shall be vegetated and stabilized to control erosion in concentrated flow areas.
(11)
Storm drain inlets shall be protected so that runoff will not enter conveyance systems without first being filtered or otherwise treated to remove sediment.
(12)
Either temporary seeding, mulching or other suitable control measures shall be used to protect exposed critical areas during construction.
(13)
A site shall be maintained and/or watered to prevent dust erosion.
(14)
Grading shall not be permitted to continue if the SPGA determines that dust is significantly impacting adjacent ways or property.
(15)
Topsoil shall be stockpiled on site to the extent practicable for use on areas to be revegetated. Said soil shall be protected so that it does not erode.
(16)
Stockpiled construction materials shall be protected so that they do not erode.
(17)
Excavated materials shall not be deposited or stored near water bodies unless authorized by the SPGA.
(18)
Construction equipment shall not cross or disturb stream channels except by means of approved crossings.
(19)
In areas of the site where construction activities will cease for more than 21 days or have permanently ceased, temporary vegetation or other stabilization measures shall be initiated, weather permitting, within 14 days.
(20)
Where inadequate vegetation exists, temporary or permanent vegetation shall be established.
(21)
Permanent protective vegetation and erosion control structures shall be installed as soon as practical in the development. Permanent vegetation shall not be considered established until the ground cover is mature enough to satisfactorily control erosion. Ground cover shall not be considered mature until at least two growing seasons have elapsed.
(22)
Whenever construction vehicle access routes intersect public roads, provisions shall be made to minimize the transport of sediment (mud) by runoff or vehicle tracking onto said roads. Where sediment is transported onto a public road surface, the road shall be cleaned thoroughly at the end of each day or more often as required by the SPGA.
H.

I.
Inspection and enforcement. The Inspector of Buildings shall enforce these regulations. If the Inspector of Buildings finds that on site conditions are in violation of these regulations or not as stated in the plan, the Inspector of Buildings may issue a stop-work order and direct the applicant to take corrective measures.
J.
Construction certification by registered professional. For any site which requires a professional site plan the SPGA may require that a certified professional verify in writing that all control measures have been installed in accordance with the plan.
K.
Sequential applications. If a project is so large or complex that a plan encompassing the total project cannot reasonably be prepared prior to initial groundbreaking, an applicant may seek authorization from the SPGA to undertake major grading activities incrementally. Approval by the SPGA of phased grading activities shall take place in two steps:
