"SAVANNAH, Ga. (WJCL) -- City workers responded to an estimated 210-gallon sewage spill Wednesday afternoon at 1312 East 70 th  Street.    The spill apparently was the result of an overflowing manhole caused by a sewer main grease blockage. The amount of the spill is classified as a minor spill under State Environmental Protection Division guidelines.   Crews cleared the stoppage and cleaned the sewer main and the area affected from the overflowing manhole in about 30 minutes. Workers also will install a manhole monitor alarm to warn of future surcharges and resulting overflows, the city said. Spill notification devices also will be put at the spill site into Casey Canal, at Eisenhower at Canal, at Sallie Mood at Canal and at Montgomery Crossroads at Canal.
