w/th state regulations. ~%e Board's ]~-l~s~r~ criteria incorporate and re- quire enforoement of th/s prohibitio~ with regard to shoreland areas. (Ex. OGG and ~x. O, p. 13). It does not appear that the city has yet adopted a shoreland ordinance'delineating, formal shoreland zoning areas, but it is clear that the geology~ hydrology and soils in the area are unsuitable for protec- tion of ground and s~rface waters.. I I I I I I I I I I I I Other Factors 60. The ]~amsey "Gateway North" municipal airport is located in the ap- proximate center of the proposed area, east of 9amsey Boulevard. It is a pub- lic ~irl~ort which serves as a base for 23 single ar~ multi-engine aircraft. It has an east/west runway; ~036~ by 130 feet, and a north/northwest- south/southeast runway, 20500 by 135 feet. Latest Federal Aviation Adminis- tration records s]~Dw total annual general aviation and military operations at this airport of 21,430 for the 12 month~ ending October 19, 1982. (Ex..~4~4). 61. ghe location of this airport increases the probability and the poten- tial severity of accidents involving hazardous waste at this proposed site. (Afternoon Tr.; p. 61). 62. Tne airport also presents a serious potential cc~flict with use of the proposed site for incineration facilities. Such facilities generally re- quir. e tall stacks to protect against nearby air pollution. Board Staff had no information on likely or average required height for such stacks, but did pro- vide information on the 'only existing Minnesota incineration facility, the Chemolite plant, which has a ~00-foot stack. (Ex. 000). FAA regulations pro- hibit obstacles 200 feet high for over three and' o~e-half miles in any direc- tioa from a public airport location (which would include this entire proposed site). They also provide more severe "i~naginary surface" limitat{ons which are fan-shaped restrictions extending outward from the ends of runways which would effect a significant port/on of the northern two-thirds of the proposed site. (Ex. 63. Aaother factor particularly affecting %tse of this site for an incin- eration facility is the potential for air inversions. Pollution Control A~ency meterolo~ists report that the most important factor in e%~dluatir~3 air inversions is the height of the inversionl and that generally, the lowest in- versions occur within or near river valleysl such as this Ramsey proposed ~o- cation. (HE ~epor~ on Shakopee, OAR Docket 1%~. 194B-83-003-AKi Finding No. 45; see further; Ex. Nl~g}. Stack height;, of ccurse~ is a major factor in deter- mining the Probability and severity of such events. 64. ~he Ramsey area is presently a primary non-attainment area for total suspended particulate matte_ri sulphur dioxide, and carbon monoxide. ~he Pol- lutic~ Control Agency is seeking redesignation of the area (from the U.S. En- vironmental Protectio~ A~ency) with regard to .these pollutants, but the fed- eral government has not yet acted on these requests. Because of litigation at the federal level~ the question of whether an incineration facility could be permitted in a nC~-attainment area is 'uncertain. Regardless of whether the area is designated 'as attainment.' or r~>n-attainmentl a new emission source would' have to install the best available or achievable control technology,
