------- § sewagi Our coastal resources are a national treasure, providing recre- ation, income and beauty. We all know that the health of our coastal waters is constantly threatened by pollution from indus- try, agriculture, and urbanization. you can put the same into the water as sewage from -one of bacterial poSlution a impacts of improper vessel sewage discharge increase in high traffic areas. •f^thi)geris;;found[iw "untreated sewage^ cainVca;use extreme -- /.illness, and .•eyemdeath. jwheri; ingested:'by humans./ : Untreated vessel: sewage dischatge is capable of suffocating •$nj'm'afe.a'hd-pla^ coral .reef commu.nities arid;shellfish: beds are particularly sensi- tive totherJmpactsfrom:Untreated;sewage, : ..- ,: , ' ------- Improper discharge can cause illness of income to others! Over 33,000 square miles (24 million acres) of U.S. coastal and estuarme waters are classified as shellfish (clam, mussel, and oyster) growing waters. Annual commercial harvests yield about 77 million pounds of shellfish, worth an estimated 200 million dollars.

Cora! reefs are one of the most spectacular and diverse ecosystems on earth. U.S. coral reef communities can be found in the Florida Keys, the Southern Atlantic, the Gulf of Mexico, the Carib- bean, and. the Western . Pacific. V Cora! reef- tourism provides significant income to Florida, Hawaii, . ^ and the U*.S. Virgin isands. Home to over 1 million species, coral reefs also support valuable commercial and recre- ational fisheries. Coral reefs-protect nearby coastal areas by reducing shore- line erosion arid providing storm protection by acting as natural stoitn surge barriers. They are also believed to be important ^untapped sources ;of medicines and bjomedicals.; Coral reefs are extremely sensitive to sewage discharge and often1 act as indicators that the.ocean waters in which they: live are -polluted; Unlike shellfish beds, -,-howeve^.-0nee they.are;gone, they, are .gone- forever.... Sadly, it is Estimated that .10% of all coral, reefs worldwide have been damaged beyond repair, and another 30% are in critical condition and likely to die within 10-20 years. The; impact fromJsewage plays a role in the decline of,coral ;• reefs. •* ;.•' . ' • ';-Vl; ' ------- Federal State Agencies Doing Their Part! The Clean Water Act (CWA) of 1972 was established to protect and restore our natural aquatic resources. Section 312 of the CWA mandates the use of marine sanitation devices (MSDs) on all vessels equipped with installed toilets. There are three type of MSDs. Type i and Type II MSDs (for vessels less than 65 feet and those equal to or greater than 65 feet, respectively) disinfect and treat sewage to reduce bacte- ria and solids. Treated sewage from Type I and Type II MSDs may be discharged at any location except within designated no-discharge zones (NDZs). Type ill MSDs are holding tanks. that provide minimal sewage treatment and can be installed on vessels of any size. Therefore,,It is illegal to discharge the: contents of Type III MSDs in any U.S. territorial waters (within 3 nautical miles of shore). Type III MSDs can only be emptied at designated on-shore pumpout and dump facilities or beyond 3 nautical miles from shore. * t •f > With the approval of EPA, States can designate a portion or all of their waters as NDZs, making .all vessel sewage dis- charges illegal. States often establish NDZs if they can demonstrate to EPA that safe and adequate pumpout and dump facilities are available. . : NDZ designations are also issued as EPA regulations follow- ; ing State applications to EPA for NDZs: « if prohibiting vessel sewage discharge is needed to protect environmentaly sensitive areas such as shellfish beds, coral reefs, and/or fish spawning areas © if the water body is a.drinking water source. To initiate the NDZ process, an interested party, group, or local government can discuss its concerns with the appropri- ate State agency that addresses vessel sewage discharges. ------- • Know the Law (http:/wwWoepa.gov.owow/ oceans/regs/vsdmsdl.html) • Know what type of marine sanitation device '(MSD) is installed on your boat. • Use • Use pumpout facilities.
