Since the rule only requires minimization (which is generally accepted
to be an 80% reduction of whatever level previously left the site), why
not simply reduce the applications of phosphorus and nitrogen so that
you gradually reduce the pollutant level leaving the site to 20% of its
previous measurement.

Is this a fertilizer application? How about slow release products, or
multiple applications of diminutive amounts only as needed and only
during growing season when it maximum uptake by vegetation is
applicable?

If it's a landscape maintenance issue, plant native species and other
low maintenance species that don't require a lot of fertilizer. Or is
this a golf course?

What about the wool bale concept?
Used in some places in New Zealand and Australia.
Local applications = Supermarket carparks, airports.
