Summary
In Pharr, construction or grading work that disturbs an acre or more must comply with a TPDES or NPDES stormwater discharge permit, and the city can demand proof of that permit before allowing any discharge into its storm drain system.
Any person subject to an industrial or construction activity TPDES or NPDES stormwater discharge permit shall comply with all provisions of such permit. Proof of compliance with said permit may be required in a form acceptable to the City of Pharr prior to the allowing of discharges to the MS4.

Full Breakdown
Pharr's stormwater article (Chapter 130, Article V) defines regulated "construction activity" to include clearing, grubbing, grading, and excavating on sites of one acre or more, tying local enforcement to the state/federal TPDES-NPDES construction permit program. Section 130-309 then requires anyone holding that permit to comply with all of its terms, and lets the city demand proof of compliance before it will allow the resulting discharge to reach the municipal separate storm sewer system (MS4). Site development plans must also route runoff into an adequate on-site drainage system under the subdivision rules in Section 118-48.
Violations & Fines
Discharging or grading without proof of an active TPDES/NPDES permit is a violation of Article V; the city can issue a written notice of violation, suspend MS4 access, require abatement/restoration at the violator's expense, and pursue criminal prosecution under Sec. 130-321.
