A is my choice.

(A) reduced the amount of phosphates that municipalities had been allowed to dump

- this one is fine.

(B) reduced the phosphate amount that municipalities had been dumping
- out . need amount of phosphate, instead of phosphate amount
(C) reduces the phosphate amount municipalities have been allowed to dump
- need amount of phosphate, instead of phosphate amount
(D) reduced the amount of phosphates that municipalities are allowed to dump
- out wrong tense. either should be reduces to parallel to are OR were allowed to parallel reduced.
(E) reduces the amount of phosphates allowed for dumping by municipalities
- out, alowed for, need allowed to

An action in past stops an action happened before it------>the pair of tenses : simple past and past perfect. Thus, we can eliminate C,D,E.
B seems ok, but it can not deliver the original meaning of the sentence as "allowed" is eliminated.

(A) reduced the amount of phosphates that municipalities had been allowed to dump

A is ok as it is.
B-phosphate amount is wrong. also tense problem-had been dumping
C-phosphate amount. also tense problem-have been allowed to dump
D-tense problem-are allowed to dump
E-tense problem-reduces the amount of phosphates allowed

1. The agreement is signed up in 1972, and so "reduced" is better than "reduces". Thus, (C) and (E) are eliminated.

2. What is reduced is "the amount", not "phosphates" itself. Thus, (B) and (C) are eliminated.

Between the remaining (A) and (D), I'd say (A) is better.

A

No error.

(B) 'allowed' is missing
(C) 'reduces' invalid tense
(D) 'municipalities are' invalid tense
(E) 'reduces' invalid tense

It was D for me ; i reason, the agreement is still in effect. Hence the latter part of the sentence must be in present tense

I remember it is D too.

my reasoning is the same as hkm_gmat's

If you use had, it means the agreement had ended sometime in the past.
