RON: "Reduce" is not an ongoing state of existence. It's something that happens at one particular point in time.
Reduce 不可持续的动作

TIM: as for A, in the same sense that you cannot go back in time and change how much was dumped, you cannot go back in time and change how much was allowed. you can only change how much was allowed from that point forward..

GUEST: It should be D. You cannot reduce the amount of phosphates that 'had been allowed' because that dumping has already been done. You can only reduce the amount that can be dumped from now on. Only D makes it clear.

RON: If this still doesn't make sense to you, put a (pre-1972) year on them. E.g., the amounts that were specified in 1969.
Perhaps that will make it more clear"”you can't reduce the amounts that were specified in 1969, because they were specified in 1969. (The current figure can represent a diminution from those historical figures, but a diminution of those figures is impossible; we can't change history.) Same issue here.

协议减少了phosphates被允许倾倒的数量
不能说是协议减少了phosphates在1900年被允许倾倒的数量。以前被倒的已经倒掉了，不能再被减少了。

以上
