Enforcement is another weak link in the regulatory framework of the estuaries. The sheer number of septic systems renders system maintenance and performance requirements unenforceable, and the state has not developed an alternative approach for ensuring proper maintenance and repair. Although the NH DES Site Specific Program has significantly improved its monitoring commitment since 1999, program staff limitations have inhibited monitoring of NH Department of Transportation projects for stormwater and erosion control. Local regulations are also only partially enforced. Enforcement officials are often not fully aware of permit requirements. In some cases, permit conditions are never monitored and there are no local programs to ensure long-term monitoring and maintenance of stormwater and erosion control measures.
