It may be in the best interest of the institution to select sampling point/points before the wastewater discharge into a POTW and conduct several analyses of water samples to get a baseline idea of how much of the RCRA metals are found in the discharge water. The local city or POTW would have their own limits on the quality of wastewater that they can accept. If the analytical results are higher than their limits, the water may have to be treated before the POTW would accept. If there are no limits coordinate with the POTW and get it in writing that the water discharged would not affect their operations and therefore is acceptable. This is very important to protect against any Notice of Violation arising out of inspections by the DEQ or the EPA. The link below has several useful information on water quality standards in Virginia.

I think your clients and their consultants are getting a bit confused about the difference between specific pre-treatment ordinances, which are in effect in certain larger cities (EPA has a tiered system) and general, federal statutory bans on disposal.
If you are disposing to a POTW and the POTW has an EPA-approved pretreatment program and issues you a permit, you can - in certain instances - dispose of materials that would be considered as hazardous waste (e.g., small concentrations of solvents, metals). If there is no approved pre-treatment plan, you may be subject to federal RCRA requirements.
As for Dr. Norwood=92s situation - Richmond has pretreatment limits and a program (although it is a bit sketchy):
Sec. 29-314. Discharge of industrial, etc., wastes into sewers--Generally.
It shall be unlawful for the owner or operator of any industrial plant or enterprise, located within or without the corporate limits of the City, to discharge or cause to be discharged, in any manner, directly or indirectly, into the sewers of the City, whether located within or without the corporate limits thereof, any water used in industrial processes, any industrial waste or liquid or other matter which injures or is likely to injure the sewers, overcharges or is likely to overcharge the sewers, or is detrimental or is likely to become detrimental to navigation, public health, safety or welfare.
(Code 1985, =A7 30-314)
Sec. 29-315. Same--Specific prohibited discharges.
(a) No industrial user of the City's wastewater system shall discharge or cause to be discharged into such system the following liquid or material:
(1) Any material which creates or may create a fire or explosion hazard at any point in the City's wastewater system;
(3) Any solids or viscous matter in an amount which may cause obstruction or interference in the wastewater system;
(4) Any material that, by its constituents, character, volume, strength or any combination thereof, may cause or contribute to an interference with the normal operation of the City's wastewater system;
(5) Heat in an amount that would inhibit biological activity or cause wastewater treatment plant influent temperature to exceed forty (40) degrees Celsius (one hundred four (104) degrees Fahrenheit).
(b) Industrial user for purposes of this section is defined to include any nondomestic source.
(Code 1985, =A7 30-315)
There is a compendium of national sewer discharge regulations that your consultant should be able to tap into, especially if they have worked with platers or photo labs in the past.
