There are certain materials and chemicals
that are strictly prohibited by Hampton Roads
Sanitation District (HRSD) from disposal down the drain. If you are uncertain about using any
particular substance that could end up down the drain, contact the Jefferson
Lab Material
Safety Data Sheet (MSDS) Coordinator at ext. 7882 for
assistance.
This appendix provides a list of prohibited materials that could be present at Jefferson Lab. Other HRSD permit information is provided in ES&H Manual Chapter 8030 Appendix T1 Discharges to the Sanitary Sewer System.
Flammable Liquids, Solids, or Gases
·
solvents
·
oil-based paints
·
fuel oils, lubricants
·
combustible gases
·
gasoline
·
benzene
Toxic or Poisonous Liquids, Solids, or Gases
·
anti-freeze
·
pesticides
Wastes with a pH < 5.0 (acid materials)
·
water from distillation systems may be acidic
·
some general purpose cleaners may be strongly acidic
·
buffered chemical polish (useful to etch
niobium cavities)
Solids or Viscous Substances that may Block
Sewer System Lines
· sand |
· ashes |
· plastics |
· asphalt |
· rags |
· metals |
· straw |
· feathers |
· glass |
· tar |
· paper cups |
· whole blood |

Excessive Discharges: can
overload the sewer system; avoid discharge of significant quantities of
unpolluted water such as:
·
rainwater
·
stormwater
·
groundwater
·
street drainage
·
yard drainage
Petroleum or Mineral Based Oils
·
motor oil
·
animal or vegetable based oils
·
fats or greases
·
greases collected from the grease trap in the CEBAF Center kitchen
Wastes with excessively high BOD (Biological Oxygen Demand) or COD (Chemical Oxygen Demand) or decomposable organic content.
·
carbonaceous material (vegetable based oils)
·
oxidizable nitrogen (fertilizers)
Strongly Odorous Wastes
Wastes containing significant amounts of
dissolved sulfides
Substances promoting toxic gas emissions when
combined with water
·
concentrated acids or bases (including cleaning solutions)
·
calcium
·
lithium
·
potassium
·
metal hydrides
High temperature wastes that may increase
treatment plant influent above 104°F (40° C) or higher
Wastes that require excessive amounts of chlorine to treat or disinfect
·
medical or biological
wastes. Refer to ES&H Manual Chapter 6800 Appendix T4 Regulated Medical Waste Management
Excessive amounts of low conductivity water,
distilled water, steam condensate, or other condensate or cooling water
discharge, or discharges from heat pumps.
Wastes that produce excessive discoloration
·
dyes
·
inks
Wastes that may precipitate, solidify, or become viscous between 50° and 100°F
Significant quantities of garbage or waste that cannot pass through a 3/8 inch (1 centimeter) screen
Any excessive quantity of blow-down or bleed water from cooling towers exceeding one third of the makeup water
Any significant quantities of single pass cooling water
Any quantities of radioactive material wastes
·
Consult RadCon to assist with disposal requirements for any radioactive
waste.
Any significant quantities of inorganic material
All other materials that could disrupt the operation of the treatment plant
NOTE: Water may not be added to wastewater for the
purpose of diluting wastes which would otherwise be unacceptable for
discharge. |
For any process waste that has not received specific HRSD approval for discharge, check with your Environmental, Safety, Health, and Quality (ESH&Q) staff before disposal.
As well, it is the duty of all personnel to minimize, correct, or prevent any discharge which most likely would have an adverse effect on human health or the environment.
Important Reminders:
·
Observe the list of prohibited discharges. If you’re not certain, don’t discard the
waste without asking your local ESH&Q staff for guidance.
·
Solid debris from cleaning operations should be separated from the
wastewater, if possible, and put in the regular trash.
