rocky shores adjacent to Type 1 and 2 waters unless the primary purpose of the alteration is 

 to preserve or enhance the feature as a conservation area or natural buffer against storms." 



Similarly, filling, removing or grading is prohibited adjacent to Type 1 and 2 waters and 

 in coastal wetlands designated for preservation adjacent to Type 3,4, and 5 waters unless as 

 a consequence of an approved mosquito-control ditching project 



A potentially important tool in control of urban runoff contamination and pollution of 

 shorefront waters is provided by the requirement that all bulk-oil transfers involving ships 

 and facilities require a permit from CRMC. 



CRMC addresses stormwater management and erosion and sediment control in more 

 detail in specific SAM plans. (See detail of the Narrow SAM plan regulatory language in 

 Appendix 2.3). Plans oudine management policies and regulations relating to stormwater 

 control, require development of stormwater management plans as part of the permitting 

 process, and set criteria for performance and design standards to be applied, citing specific 

 publications as design references. 



Stormwater management is defined as relating to both quantitative and qualitative 

 control. For quantitative control, stormwater management refers to a "system of vegetative 

 and structural measures that control the increased volume and rate of surface water runoff 

 caused by man-made changes to the land;" for qualitative control, vegetative , structural, 

 and other measures are designed to "reduce or eliminate pollutants that might otherwise be 

 carried off by surface runoff." 



Remedial stormwater management activities are addressed in a more general way in the 

 SAM plans. Section 320.2 F. of the Narrow River SAM plan, for example, defines 

 remedial actions as those which are taken to address a simation where no stormwater 

 management presendy exists and there is a clear threat to water quality which the proposed 

 activity addresses. Pan F 2) provides for the granting of Special Exceptions, under the 

 requirements of Section 130 of the CRMP, for new or expanded discharges of stormwater. 



The section states that CRMC "shall give strict consideration to paragraphs A(2) and A 

 (3) of Section 130, which stipulate that all reasonable steps shall be taken to minimize the 

 environmental impacts and/or use conflicts, and that there is no reasonable alternative 

 means of, or location for serving the compelling public purpose cited." 



Further, Section 320.2 G recommends that CRMC, DEM, and the towns undertake a 

 cooperative program to upgrade existing direct discharges which do not employ, or possess 

 substandard, stormwater management techniques and are discharging into the (Narrow 

 River) and its tributaries and wedands, integrating the standards and design techniques 

 presendy being evaluated by DEM. Recommendations for further scientific and technical 

 research and demonstration projects are also included. 



CRMC staff limitations are such that insufficient resources are available 

 for foHow^up to ensure that permit conditions are met, and that applicants 

 comply with permit conditions in the long term. Given the maintenance 

 requirements of non-point source controls, lack of enforcement capability will create 

 increasing program vulnerability as requirements for BMP installation are attached to 

 permits. The Executive Director acknowledges that enforcement capability is inadequate to 

 meet current needs.
