OG-11^th的答案是D

An agreement that occurred in 1972 is correctly described with the past tens verb reduced.Since the dumping continues into the present, the past perfect verb had been allowed should instead be the present are allowed.

A Had been allowed should be are allowed.

B The phosphbates amount should be the amount of phosphates;the meaning of the sentence is changed by the omission of any form of allow.

C The present tense reduces should be the past tense reduced;the phosphate amount should be the amount of phosphates;have been allowed should be are allowed

D Correct.The past tense reduced is correctly used in this sentence to describe a past action,and the present tense are allowed is used to describle the present situation.

E The present tense reduces should be the past tense redueced;allowed for dumping is an incorrect idiom;allowed for dumping by municipalities is awkward
