A. 
The purpose of these performance standards is to ensure that any allowed use can be conducted in a manner which would not adversely affect the surrounding natural or human environment by creating a dangerous, injurious or objectionable condition.
B. 
These performance standards shall be enforced by the Building Commissioner for the Town and will be in force throughout the life of the use or related structure(s).
C. 
Measurements to confirm compliance with these standards shall be provided by the applicant if requested by the Building Commissioner. The determination of the existence of any dangerous or objectionable elements shall be made at or beyond the property lines of the use creating such elements, wherever the effect is greatest. Measurements may be made by any public or private agency, firm or person competent to perform such activity.
A. 
Exterior area lighting, including but not limited to lighting for parking lots, recreational areas, walks, drives and outside building walls, shall be done in such a manner so as to direct light away from adjacent lots and public ways.
B. 
Light overspill onto adjacent areas shall not exceed 0.5 footcandle measured in residential districts or three footcandles measured in nonresidential districts, except that if the ambient level exceeds that, then overspill shall not be such as to create observable shadows.
C. 
No flickering or flashing lights shall be permitted.
D. 
No light shall be attached to a freestanding pole or pylon taller than 25 feet except in the Planned Commercial Village Center, where poles or pylons up to 30 feet are allowed. Installation methods employed for lights located on posts or pylons that are greater than 10 feet at their highest point must be reviewed and certified for safety by the Building Commissioner. Structural drawings and specifications for the installation, including the foundation, shall be submitted by a professional engineer registered in the Commonwealth of Massachusetts so as to conform to the State Building Code.
E. 
All streets shall be safely lit.
A. 
Excessive noise at unreasonable hours shall be muffled so as not to be objectionable due to volume, frequency, shrillness or intermittence.
B. 
No noise shall be in excess of 55 decibels at any lot line opposite or abutting a residential use or in excess of 90 decibels at any other line, except for temporary construction or maintenance work, agricultural activity, timber harvesting, traffic, church bells, emergency warning devices, parades or other similar special circumstances.
C. 
In a residential district, noise shall not exceed 55 decibels between the hours of 9:00 p.m. and 7:00 a.m. and, at all other times, shall not exceed 55 decibels at any residential lot line for more than 20 minutes in each hour.
No vibration shall be produced which is transmitted through the ground and is detectable without the aid of instruments at or at any point beyond the lot line, except for blasting and other activities within the jurisdiction of the Board of Fire Prevention Regulations.
Atmospheric emissions of gaseous or particulate matter generated by land use shall conform to the then-current regulations of the Massachusetts Division of Environmental Protection. The applicant may be required to produce plans and specifications of detail sufficient for review by the DEP at the request of the special permit granting authority and/or Board of Health. Determination by the DEP that potential exists for emissions in excess of allowable limits shall be grounds for permit refusal.
There shall be no emissions of toxic or noxious matter or objectionable odors of any kind in such quantity as to be readily detectable at the property line of the lot on which the use emitting the toxic or noxious material or odor is located. For the purposes of this section, "toxic or noxious matter" is any solid, liquid or gaseous matter, including but not limited to gases, vapors, dusts, fumes and mists, containing properties which, by chemical or other means, are inherently harmful to destroy life or impair health or capable of causing injury to the well-being of persons or damage to property.
A. 
All activities and all storage of flammable and explosive materials at any point shall have adequate firefighting and fire-suppression devices and equipment.
B. 
No highly flammable or explosive liquids, solids or gases shall be stored in bulk above the ground, unless they are located in anchored tanks at least 75 feet from any lot line or Town way or 40 feet from the lot line for underground tanks. All relevant federal and state regulations shall be met.
C. 
Propane gas tanks in 100-pound cylinders (or smaller) shall be exempt from these safety regulations.
No activities that emit dangerous radioactivity at any point shall be permitted.
No electrical disturbance which adversely affects the operation at any point of any equipment, other than that of the creator of such disturbance, shall be permitted.
The use and discharge of substances into private sewer systems, lakes, streams, similar water bodies or directly into the ground shall not violate the rules and regulations of the Lee Conservation Commission, the Massachusetts Division of Environmental Protection or the Massachusetts Division of Water Pollution Control.
A. 
No waste material, liquid or solid, or refuse shall be dumped upon, or permitted to remain upon, any part of the lot or tract outside of the buildings constructed thereon.
B. 
Any waste material, liquid or solid, or refuse stored outside the buildings shall be sorted into secure containers in such a manner that wind, rain, other environmental factors, animals and humans cannot cause a nuisance or hazard by gaining access to the materials and allowing the materials to escape from the secure containers by scattering, leaking, draining or other means. It is equally important that edible wastes be secured from access to rodents or insects. Finally, it is intended that all waste that is currently recyclable be segregated into clearly identified containers for that use by the Commonwealth of Massachusetts.
C. 
Roll-off containers.
(1) 
Definition: receptacles generally used to contain construction and demolition waste with a capacity of 10 cubic yards or more.
(2) 
Roll-off containers must display the name and valid contact information of the owner.
(3) 
Roll-off containers must be placed in a location that does not create a nuisance or potential health hazard.
(4) 
Where and when the work site permits, roll-off containers must be placed at least 25 feet from any public way or lot line.
(5) 
Roll-off containers may be kept on a job site as long as they are in use. They must be emptied when the average height of the contents extends over the edge of the container.
(6) 
Roll-off containers must be removed from the work site when construction or demolition work has ceased.
(7) 
Storage of inactive roll-off containers is restricted to the operations base of the owner(s).
(8) 
Violation of rules concerning roll-off containers will result in fines as delineated in Article XIII of this chapter of the Code of the Town of Lee.
The rate of surface water runoff from a site shall not show an increase after construction. If needed to meet this requirement and to maximize groundwater recharge, increased runoff from impervious surfaces shall be recharged on-site by being diverted to vegetated surfaces for infiltration or through the use of detention ponds. Dry wells shall be used only where other methods are not feasible and shall require oil, grease and sediment traps to facilitate removal of contaminants.
A. 
Whenever the existing contours of the land are altered during construction or otherwise, the land shall be left in a usable condition, graded in a manner to prevent the erosion of soil and the alteration of the runoff of water to or from abutting properties, and shall be suitably landscaped. Whenever a structure is involved, the remediation described above shall be accomplished within six months of occupancy of the structure.
B. 
Dust control shall be used during grading operations.
C. 
All requirements of the Lee Conservation Commission and the Massachusetts Department of Environmental Protection must be adhered to.
Accessory dish antennas shall be located in the rear yard, shall be set back at least 10 feet from all property lines, principal buildings and accessory buildings and shall not have a diameter greater than 1/3 of the required rear yard. Satellite dish antennas with a diameter of four feet or less may be installed on rooftops as long as they are not visually obtrusive as viewed from the street.
A. 
Wind energy conversion systems, machinery and equipment shall not cause interference with radio and/or television broadcasting or reception and shall comply with the provisions of 47 CFR 15 (Federal Communications Commission), as it exists or as it may be amended.
