Document Page: BETTER DATA AND EVALUATION OF URBAN RUNOFF PROGRAMS NEEDED TO ASSEDD EFF... - 0 views

  • The Chesapeake Bay, forexample, has been polluted with the nutrients nitrogen andphosphorus and with excess sediment caused, in part, by urbanrunoff. The excess nutrients cause algae blooms that blocksunlight from reaching bay grasses-which are a source of food,shelter, and nursery grounds for many aquatic species.
  • In aneffort to control nutrient pollution in the Chesapeake Bay, theExecutive Council of the Chesapeake Bay Program" established agoal to reduce the nitrogen and phosphorus entering theChesapeake Bay by 40 percent, including through control of runofffrom urban areas.

      The Santa Monica Bay Restoration Project conducted a study to identify adverse health effects of untreated urban runoff by surveying over 13,000 swimmers at three bay beaches. The study established a positive association between an increased risk of explains health outcome measures at various distances from storm drains. For example, the study found a 1-in-14 chance of fever for swimmers in front of the drain versus a 1-in-22 chance at 400 or more yards away.

High PAHand heavy metal concentrations were found in crayfish tissuesamples from several urban streams in Milwaukee. The studyassociated these contaminants with storm water runoff.
  • The three primaryactivities used in these programs include efforts to characterizestorm water runoff; BMPs aimed at reducing pollutants in stormwater runoff to the maximum extent practicable; and reportingprogram activities, monitoring results, and costs of implementingthe program. Some BMPs are structural-meaning that they aredesigned to trap and detain runoff until constituents settle orare filtered out.

  • Several officials in the cities we visited said that their annualcosts are likely to increase. A number of factors could affectthe costs. For example, a Baltimore City official explained thatthe anticipated, future program costs depend on several factors,including (1) requirements in watershed- management planscurrently being developed, (2) pollution-reduction goals the citywill be required to achieve, (3) requirements of the stateregulatory agency in future permits, and (4) requirements thecity may have to meet if TMDLs or numeric effluent limits areincorporated into NPDES storm water permits. Other city officialsalso expressed concern about the extent to which TMDLs couldaffect their future costs. These city officials are concernedthat when and if TMDLs are established, their future storm waterpermits may require that storm water runoff meet specific waterquality standards. For example, Los Angeles County's trash TMDLcould potentially drive the county's storm water management costsupward, and the county expects additional TMDLs to be imposed. Onthe other hand, Worcester officials estimated that their futurestorm water costs would be about the same as they were at thetime of our review-about $4.5 million per year.

Kids Search - powered by EBSCOhost: HAPPY NEW YEAR - 0 views

  • Section: Festival The Lunar New Year is the most important festival of the Chinese year. It is the celebration to welcome the start of a new year and a festival of family reunion. Families who live apart come together to celebrate. Although outside the Chinese-speaking world (China, Taiwan, Singapore, and some parts of Malaysia) Chinese New Year is not a public holiday, people still celebrate with a family get-together and a special meal, either on Chinese New Year's Eve or on the first weekend after the Chinese New Year. Chinese New Year is a family celebration that takes place in the home. The Chinese place particular importance on caring for the family. This is particularly true at the New Year Festival when the very young are treated specially because of their importance for the future, and the old are honored for their connection with the past. Public celebrations of Chinese New Year happen all over the world; cities with Chinese communities celebrate with Lion and Dragon Dances and parades with traditional costumes. They also welcome the new year with firecrackers. In China many places have traditional celebrations that last for several days. ~~~~~~~~By Sarah Moyse This article is copyrighted.
