Photographic Fixer Management Program Over the past decade, the number of photoprocessing laboratories has greatly reduced on campus. Most laboratories have gone to digital photoprocessing. For laboratories that still use photographic fixer, photographic fixer is properly disposed or recycled.

Campus fixer users are informed through the Information and Education Program that they must collect fixer in labeled containers. EH&S picks up the containers and ships them as hazardous waste to a silver recycling vendor. The campus disposes of or recycles silver bearing fixer through a licensed hazardous waste treatment contractor. In addition, photographic laboratory sinks are posted with “No Fixer” signs that state the discharge of fixer to the sanitary sewer is prohibited.

EH&S maintains a listing of photographic chemical users. Lists of the names of the users and their location on campus are generated using the CISIS and the CWTS databases.

Mercury Thermometer Exchange Program (“Make UCB Mercury Free”) In 2004, EH&S partnered with EBMUD to create the Mercury Thermometer Exchange Program. EH&S and EBMUD collected over 3,600 mercury-filled thermometers and reduced the emergency response for broken thermometers by collecting over 1,160 additional pounds of mercury-containing equipment. EH&S continues to exchange mercury-filled thermometers with alcohol-filled thermometers.

Slug Discharge Prevention and Contingency Plan (SDPC) The Slug Discharge Prevention and Contingency Plan (Attachment B) includes:

• A listing of slug discharge prevention practices • Notification procedures to be followed in the event that prohibited priority pollutants are

discharged to the sanitary sewer and • Pollution prevention and notification training requirements for chemical users

The SDPC Plan is implemented for all campus chemical users in laboratories, shops and physical plant operations.

Standard Operating Procedures and Specifications UC Berkeley has created procedures for common discharges that may take place on the Berkeley campus. See Attachment C for procedures for staff. These procedures are also incorporated into the Information and Education Program.

UC Berkeley also has a Storm Water Pollution Prevention Specification (Attachment D) given to construction projects. The specification specifies the standard operating procedures for building washing (Attachment 1 of the specification).

SECTION 02210Attachment 1

Procedure For Wastewater Management FromUC Berkeley Building Washing And Maintenance Operations

This procedure describes wastewater management for UC Berkeley building washing operations and isto be used in conjunction with all operations where building exterior surface cleaning generates wash-water. Wastewater from washing operations is prohibited from discharge to storm drains because i tmay contain chloramines, cleaning compounds, or materials dislodged from the building surfaces duringcleaning (such as leaded paint). Wastewater may be disposed to landscaped areas or the sanitarysewer on the condition that contaminant concentrations will not harm the landscape or the sewagetreatment facility’s operations.

Offsite disposal through the Office of Environment, Health & Safety (EH&S) may be necessary i fcontaminants in the wash-water exceed sewer discharge contaminant limits. If cleaning compoundscontaining surfactants, detergents or other chemicals are used in the cleaning process and there aresludges or residues that need to be disposed of, contact EH&S, 642-3073, for disposal guidance.

Building Washing Wastewater Management Procedures

Unpainted Buildings• Construct a containment system to eliminate wash-water discharge to the storm drain.• Divert wash-water onto landscaping (preferable) or into the sanitary sewer.• If high pressure water is used (e.g., hydro-blasting to remove spalled concrete) then settle outthe solids using a containment tank, or filter out the solids using filter fabric or other solids removalmethod.

Painted Buildings• Construct a containment system to eliminate wash-water from draining to the storm drain or thesanitary sewer system.• Pour, pump or drain the wash-water into a containment tank.• Use a filter system (e.g., cartridge filters) to remove suspended paint solids. Use settlingmethods to minimize the amount of solids entering the filter system. This will prevent filtersaturation.• Sample the filtered water before it is discharge to the sanitary sewer. Have the sampleanalyzed for the 13 priority pollutant metals (antimony, arsenic, beryllium, cadmium, chromium,copper, lead, mercury, nickel, selenium, silver, thallium, zinc) and any other chemicals of concernthat could be present to determine whether or not the water is suitable for sanitary sewerdischarge. Send a copy of the analytical results to EH&S for disposal method determination.• If the analytical results exceed the EBMUD discharge limits, consider options for using a finerpore size filter, or dispose of the water through EH&S. EH&S will arrange to ship the water to aproperly permitted disposal facility.



SECTION 02210Attachment 2

Procedure For Preventing Chlorinated Water From EnteringThe Storm Drain System Using Sodium Sulfite Tablets

PurposeThese procedures describe how to manually dechlorinate discharges of domestic water using sodiumthiosulfate solution prior to release into storm sewer systems or receiving waters in accordance withRegional Water Quality Control Board requirements.

This procedure is limited to domestic water discharges with a chlorine residual of 2 mg/L or less.Dechlorinating superchlorinated water (chlorine residual of 50-200 mg/L) is not addressed in thisprocedure. Contact EH&S, 642-3073, for guidance on discharging superchlorinated water.

Dechlorination Procedure OverviewDechlorination of chlorinated water discharges is accomplished by the addition of tablets comprised of90% sodium sulfite to the discharge flow. For discharges from trenches during main breaks, the tabletsare placed inside synthetic mesh fabric pockets sewn together in a grid or line (called a “dechlor mat” or“dechlor strip” respectively). The dechlor mat or strip is laid across the flow path or over the stormdrain and either weighted down or nailed to the street to keep it in place.

In all cases, as the discharged water flows over and around the tablets, chemical is released as thewater contacts the tablets, reacting with and destroying the chlorination. The key to the success of thisprocedure requires effective contact between the flow and the tablets. This is accomplished by ensuringthe tablets are well-distributed across the flow path. The tablets must be spaced no more than 4” apartfor gravity discharges at ambient pressure. For discharges under pressure (such as pumping), the tabletsshould be spaced as close together as possible without constricting the flow. The various tablet holderdesigns are fabricated to ensure that this specification is met.

Selection Criteria For Dechlor Mat or Dechlor Strip For Use In Gravity Discharges

This decision is ultimately up to the preferences of the user as long as the tablets are well distributedacross the flow path. The mats can cover a larger area so if the discharge flow is large and spread out,mats may be easier to use than multiple strips. Mats are also sized to cover storm drain inlets so if theflow is not well channelized, it may be easier to locate mats over the storm drain(s) the flow isultimately discharging into rather than laying out strips or mats upstream of this point. Strips aresmaller, take up less space in vehicles and multiple strips can be used to cover larger flows so theirconvenience and flexibility make them the appropriate choice unless some of the conditions describedabove are encountered.

Dechlorination EquipmentThe following equipment is needed for dechlorination when following this procedure:

Dechlor mat (3’ x 4’) -or-Dechlor strip (3’ x 6”) -or-Diffuser with tablet chamber -or-Diffuser with mesh tablet holder -and-Dechlor tablets (45 lb bucket) -and-DPD Powder-Pop Dispenser -and-



Attachment 2 continued

WARNING!Don’t use sodium sulfite with calcium hypochlorite (HTH) or sodium hypochlorite (used to disinfectwater distribution system mains or appurtenances). These two chemicals can react when mixed in thepresence of water. The reaction can produce heat and both hydrogen and chlorine gas, creating both apotentially toxic and explosive/flammable atmosphere. These chemicals and associated mixing anddispensing equipment must be kept segregated from each other at all times. Should the chemicalsbecome mixed, call EH&S 642-3073.

Procedure 1—Dechlorination For Releases From Trenches During Water Main Breaks

Fill Pockets With TabletsPut one tablet in each pocket of the dechlor mat or strip. If the pocket contains a partially-used tablet,add another tablet only if there is room.

Place Dechlor Mat Or Strip In flow PathPlace the dechlor mat or strip across (perpendicular to) the flow path downstream of sediment controldevices (e.g., pea gravel bags). Nail the mat or strip to the street using street nails (through thegrommets in either end of the mat) or weigh the mat or strip down to ensure that it stays in place. If theflow path is more than 4’ wide (width of dechlor mat) when using a dechlor mat or 3’ wide (width ofdechlor strip) when using a dechlor strip or there is more than one flow path (flow is spreading out inmore than one direction), use additional mats to ensure all water from the source is crossing a mat. If theflow is deep (more than 1” above the top of the dechlor mat) and/or the flowrate is very high (>300GPM), a second mat should be placed downstream of the first mat to ensure adequate dechlorination.

Monitor Mat Or StripCheck the dechlor mat periodically to ensure some tablet remains in each pocket and that all flow iscrossing at least one mat.

Clean-upWhen the discharge is complete, move the dechlor mat(s) or strip(s) to the storm drain(s) where thedischarge was entering, placing it on the upstream side of the grate. Hose the flow path to remove anytablet residual, ensuring that the flow enters the storm drain(s) upon which the dechlor mat(s) orstrip(s) is installed. If the flow path separates and some flow travels to a different storm drain, adechlor mat or strip should be installed at that location as well.

Tablet Disposal

Tablets Shelf LifeTablets have a relatively long shelf life unless exposed to high temperatures (>85∞F). At highertemperatures, tablets may crumble. During the summer months, crews may need to place enough tabletsfor daily use in coolers for storage on trucks at the beginning of each workday. Supply buckets must bekept in a cool storage location.

Powdered Tablet Waste DisposalAs long as tablets are in large enough pieces to be retained within the mesh dechlor, diffuser chamber ordiffuser mesh pockets, they can be used for dechlorination per the procedures contained herein. Smallamounts of powdery or granular tablet waste from tablet supply buckets or secondary containers should bemixed with water and discharged to the sanitary sewer.

1. Introduction Disposal of chemicals into the sanitary sewer is regulated by federal and state laws and regulations, by the local East Bay Municipal Utility District (EBMUD) Ordinance and by the EBMUD Wastewater Discharge Permit issued to the campus. These laws and regulations prohibit any drain disposal of hazardous wastes and limit the allowable wastewater concentration of a number of specific substances. The University of California, Berkeley (UC Berkeley) is committed to protection of the local community and the environment through strict compliance with these laws and regulations. Discharge of hazardous chemical wastes into the campus sanitary sewer system is prohibited by campus policy (Water Protection Policy, http://campuspol.chance.berkeley.edu/policies/waterprotection.pdf). The range of substances that can be considered hazardous waste is enormous. Indeed, almost any substance is a hazardous waste if it is disposed of in large quantities or in high concentrations. Federal and California laws permit laboratories to drain dispose small amounts of some chemicals in quantities that do not pose a hazard to human health or the environment. The following requirements for drain disposal of chemicals at the UC Berkeley were developed by the Laboratory Operations & Safety Committee (LO&SC) together with the Office of Environment Health & Safety (EH&S). These requirements are based on state law, EBMUD regulations and permits, and on procedures set forth in the National Research Council (NRC) publication "Prudent Practices for Disposal of Chemicals from Laboratories," National Academy Press, Washington D.C., 1983 (Reference 1) and "Prudent Practices for Handling of Hazardous Chemicals in Laboratories," National Academy Press, Washington D.C., 1981 (Reference 2). Drain disposal is permitted by campus policy only within the requirements set forth in this document. Disposal of radioactive materials into the sanitary sewer is not authorized. All liquids generated as part of radioactive materials experiments must be collected and sampled for radioactivity. Any sample whose count rate is more than three standard deviations above background, (e.g. good approximation is: 𝑏𝑘𝑔 +(3�𝑏𝑘𝑔)) is considered a statistically significant amount of radioactivity above background and must be collected for disposal through EH&S as radioactive waste. Any aqueous sample with a count rate below this threshold can be disposed of if they meet all other criteria laid out in this document. Mixed radioactive waste (waste containing both radioactive and chemical components) must be collected by EH&S for proper disposal. This version of the Drain Disposal Restrictions replaces any previous versions. Notice: EBMUD regularly monitors campus wastewater. Failure to comply with wastewater discharge regulations could lead to fines of up to $25,000 per day and/or restrictions on University water use. Notice: Laboratory and facility management operations at Richmond Field Station must follow City of Richmond Wastewater Discharge Requirements for chemical drain disposal. City of Richmond requirements have been incorporated into these Drain Disposal Requirements. All other Field Stations are advised to contact EH&S for drain disposal guidance, as these requirements may not apply due to local ordinances.

2. Overview of Drain Disposal of Chemicals Campus interior drains (and several outside drains) are connected to sanitary sewer systems, and their effluent drains to the EBMUD water pollution control plant. Chemicals and some food wastes may be prohibited from drain disposal for a variety of reasons. Radioactive materials are prohibited from drain disposal.



Potential Problems at EBMUD Water Pollution Control Plant: Chemicals and some food wastes may be prohibited from disposal to the water pollution control plant because they:

• interfere with the biological processes of sewage treatment, • are not digested in the sewage treatment process, pass through treatment and are

released as pollutants to the air, • are released to San Francisco Bay where they are toxic to aquatic organisms or where they

accumulate in Bay sediments, • concentrate in the sewage treatment sludge, compromising EBMUD's ability to use the

sludge for beneficial purposes, • cause blockages in sewers that result in sewage backing up into buildings or discharges

from manholes where raw sewage could come into contact with humans and the environment.

UC Berkeley policies governing drain disposal of chemicals and certain food wastes to campus sewers have specifically been formulated to comply with these prohibitions. In addition, Bay Area Air Quality Management District (BAAQMD) air toxics regulations require EBMUD to reduce their release of reactive organic gases (ozone precursors) and other toxic air contaminants. One strategy EBMUD uses to reduce air emissions from the water pollution control plant is source control, limiting the release of chemicals through permit restrictions. For example, for the campus EBMUD has set very low limits for discharge of chlorinated hydrocarbons to the wastewater, which are eventually released as toxic air contaminants from the water pollution control plant.

Potential Problems in Drains and Campus Sewers:

Chemicals and some food wastes may be prohibited from disposal to laboratory drains because they can:

• create hazards of fire, explosion, or local air pollution or stench, • react with other chemicals to form hazardous gases, • corrode lab and building plumbing, • leak out of old pipes as liquid to pollute campus grounds, • escape from sewer pipes as air pollutants, • expose plumbers to contact or inhalation hazards.

Campus drains are generally interconnected; substances that go down one sink drain may well come up as a vapor in another. Sinks are usually communal property, and there is a very real hazard of chemicals from two sources contacting one another; the sulfide poured into one drain may contact the acid poured into another with unpleasant consequences for all in the building. Much of the campus plumbing infrastructure is old and may not be resistant to chemicals placed into the drains. The cost of replacing corroded plumbing can easily exceed the cost of disposal of corrosive chemicals as hazardous waste.

3. Characteristics of Hazardous Wastes Hazardous wastes are prohibited from discharge. Chemical wastes are hazardous if they are: • corrosive • reactive • ignitable • moderately or highly toxic Waste that contains both a radioactive constituent and a chemical which is prohibited from drain disposal is called a “mixed waste.” Disposal of mixed waste into the campus sewer system is prohibited. Production of mixed waste is to be avoided or minimized. When mixed waste is generated, store it in a safe and protected location. Contact EH&S (642-3073) for disposal of mixed waste.



Drain Disposal of Biohazardous Wastes Disposal of infectious or biohazardous waste, as defined by the California Department of Public Health (CDPH), into the campus sewer system is prohibited. Infectious or biohazardous waste must be handled, stored, treated, and disposed of in accordance with the California Medical Waste Management Act and requirements of Biological Use Authorizations (BUAs).

4. General Rules for Sanitary Drain Disposal

A. General Rules for Sanitary Drain Disposal of Chemicals The following general rules apply to drain disposal of chemicals to sanitary sewers at UC Berkeley*. Disposal of chemicals is limited to occasional disposal of small amounts of chemicals, as detailed in the requirements below. Large scale or continuous disposal of any chemical is permitted only with the written approval of the LO&SC (Lab Operations & Safety Committee). (EH&S should be contacted to obtain this approval.)

a. Only water-soluble substances** may be disposed of in sinks, toilets, and floor

drains. Solutions should be flushed down the drain with an appropriate amount of water. [Residue animal or vegetable fats and oils generated as a result of normal cleaning activities are an exception to the solubility rule. However, significant amounts of these oils and fats (approximately more than a pint) can cause clogging in interior drains and so should be collected and disposed of appropriately (see Appendix V for additional guidance on solubility).]

(Note**: A compound is considered water-soluble if it dissolves to the extent of at least 3%. In general, a soluble substance that contains a substance that is not soluble should not be poured down the drain. However, if the water-insoluble material comprises less than about 2% of the mixture, drain disposal is usually acceptable because the small quantity of water-insoluble material will be well dispersed in the aqueous effluent.)

b. Only acid and base solutions in the range of pH 5-10 may be disposed of in the sink. At Richmond Field Station, only acid and basic solutions in the range of pH 6-10 may be disposed of in the sink.

c. Highly toxic, malodorous, or lachrymatory (that is, those that cause strong eye

irritation) chemicals shall not be disposed of down the drain. d. Unless EH&S has provided prior written approval, unwanted or waste chemicals and

products must not be poured down the drain, treated or diluted as a means of disposal. These materials must be picked up by EH&S personnel.

* Adapted from Reference 2, pp 231-232. ** Adapted from Reference 1, pp 52-53.



5. Specific Requirements for Laboratory Drain Disposal We divide chemicals into three groups with regard to drain disposal in laboratories: (1) Class A.

Class A includes chemicals that pose little or no hazard in dilute aqueous solution. These aqueous solutions are suitable for disposal down the drain in quantities of up to about 100 g of solute per laboratory per day (e.g. 100 g of ethanol in one liter of water).

(2) Class B.

Class B includes chemicals of moderate hazard in dilute aqueous solution. These aqueous solutions are suitable for disposal down the drain with excess water in quantities no greater than 1 g of solute per laboratory per day.

(3) Class C.

Class C includes chemicals that may not be drain disposed in any amount except by written approval of the LOSC or their delegate. Normally requests for exceptions are made to EH&S who obtains any necessary additional information and coordinates review by the Committee(s).

Class A chemicals include many simple organic and inorganic compounds, as well as common inorganic chemicals. Included in Class A are most biological metabolites and nontoxic cellular constituents (proteins, nucleic acids, carbohydrates, soluble fats, and their precursors and catabolites). A partial list of Class A chemicals, derived from State regulations and Appendix K of Reference 2, is provided below in Appendix I. Class B chemicals include all of the chemicals listed as toxic (T) in the California Code of Regulations Section 22-66261.30 et. seq. that are water soluble, except for those listed as Class A chemicals in Appendix I or Class C chemicals in Appendix III. Class B chemicals also include all inorganic salts listed in reference 2 as "high hazard" in tables 6.1 and 6.2. A partial list of Class B chemicals appears in Appendix II. Class C chemicals include all chemicals that are not soluble as defined above, chemicals that cause unacceptable concentrations of offensive, toxic or explosive vapors, and chemicals that are toxic or reactive at concentrations below 1 ppm in aqueous solution. Class C chemicals include the chemicals identified in the Main Campus EBMUD Wastewater Discharge Permit "Priority Pollutant Management Plan" Compliance Requirement (Federal Clean Water Act priority pollutants listed in 40 CFR Part 122 Appendix D, Tables II and III). A partial list of Class C chemicals appears in Appendix III.

6. Specific Drain Disposal Requirements for Shops, Studios, Kitchens, Janitorial Areas, Grounds, Athletics Operations, Maintenance Operations, and Construction Sites

Drain Disposable Chemicals and Process Wastewater Chemicals and wastewater of little or no hazard in dilute solutions are suitable for disposal down the drain in quantities that would be expected in normal operations (for example, latex paint brush wash-water or a bucket of mop water). Large quantity wastewater discharges from physical plant equipment can be drain disposed if approved by EBMUD (for example, cooling tower discharges and boiler blow-down).



Following are examples of drain disposable chemicals and process wastewater for shops, physical plant operations, kitchens, janitorial, grounds, and athletic operations.

• Latex paint wash-water from the rinsing of brushes, rollers, sprayers, and other water base painting equipment washing.

• Drywall compound wash-water. • Commercially available custodial and cleaning products such as soaps and detergents if

they are used in accordance with the manufacturer instructions. • Super-chlorinated water used to disinfect new plumbing. • Photographic developer solutions, neutralized (does not include used fixer solutions). • Garbage truck and dumpster wash-out. • Building wash-water that is managed in accordance with the Procedures for Wastewater

Management from UC Berkeley Building Washing and Maintenance Operations.

Hazardous Chemicals That Are Prohibited From Drain Disposal The following are prohibited from drain disposal. ORGANIC CHEMICALS

• All alkanes and water-insoluble hydrocarbons, including:

Mineral spirits Stoddard solvent Paint stripper (e.g., Jasco) Petroleum hydrocarbons Naptha Solvent based adhesives

• All chlorinated and brominated solvents, including:

Methylene chloride (dichloromethane) Tetrachloroethylene (perchloroethylene) Trichloroethane Trichloroethylene

• Chlorofluorocarbons (freons) • Concentrated acids and bases (pH <5 or >10) * At Richmond Field Station, concentrated

acids with a pH<6 are prohibited. • Latex paint (other than wash-water) • Oil and grease (e.g., crankcase oil, lube oil, grease (all kinds), vegetable oil, shortening)



• Oil based paint • Oil based paint solvents • PCBs (polychlorinated biphenyls) • EPA Priority Pollutants (See Appendix C)

7. Accidental Spill Prevention and Emergency Notification UC Berkeley's EBMUD Wastewater Discharge Permit requires that the campus maintain a Slug Discharge* Prevention and Contingency (SDPC) Plan. The purpose of this SDPC Plan is to eliminate or minimize the potential for an accidental, or slug discharge of any pollutant including laboratory, construction, maintenance, and photoprocessing chemicals which could interfere with EBMUD's Wastewater Treatment Plant.

*Definition of a Slug Discharge For the purposes of this plan, a slug discharge means any discharge of a non-routine, episodic nature, including but not limited to:

• an accidental spill or a non-customary batch discharge, • discharges that exceed EBMUD Ordinance 311 limitations, • hazardous waste discharges, and • discharges that are not allowed by these Drain Disposal Restrictions for Chemicals at

UC Berkeley. Due to the diverse nature of laboratory, shop, construction, and facility operations that use, store, and handle chemicals, the SDPC Plan does not contain specific prevention practices for all campus operations. General best management practices (BMPs) for spill prevention applicable to all chemical use, handling, and storage operations are presented below. These spill prevention measures should be incorporated as standard operating procedures for chemical use operations. Measures for containing toxic organic and inorganic pollutants, including solvents, from laboratories, shops, construction, and facilities operations:

General best management practices for slug discharge prevention: • avoid open container use of chemicals near sinks and floor drains, • where open container use of chemicals near sinks and floor drains is

unavoidable, cap or plug sinks and drains during chemical use, • store chemicals in tubs, cabinets, bermed or diked areas, or in other secondary

containment, • avoid storing excess quantities of chemicals - order only what you need and

dispose of unwanted or expired chemicals through EH&S, • secure storage cabinets and shelves to prevent tipping or falling, • use proper container restraints, • maintain spill containment and clean-up materials nearby, and • follow good housekeeping practices - never use sinks to store chemicals.



Inspection and maintenance of storage areas: All chemical use and storage areas (for example, storerooms) should be inspected for BMP implementation on a regular basis. Storerooms that contain floor drains routed to the sanitary sewer should have the floor drains plugged at all times, except when floor drains are needed (for example, when floors are mopped). Storerooms should use removable drain plugs in such cases.

Material handling and transfer:

When chemicals are transferred within buildings or between buildings, they should be placed in secondary containers which can contain over 100% of the chemical, should the primary container break.

Loading and unloading operations:

Most exterior loading and unloading locations (loading docks) drain to the storm drain system, and storm water pollution prevention BMPs should be followed. Where locations drain to the sanitary sewer, floor drains should be plugged at all times, except when floor drains are needed (for example, when floors are mopped). Temporary drain plugs should be used during time when floor drains are not in use.

Control of site runoff:

Most site runoff drains to the storm drain system, and storm water pollution prevention BMPs should be followed for any operation that has the potential for discharging a pollutant to the storm drain. Prior to initiating any operation, determine the location and drainage route of all drains. Storm water pollution prevention or slug discharge BMPs should be implemented as necessary. For more information regarding storm water pollution prevention BMPs, contact EH&S at 642-3073.

Worker training:

All laboratory, photoprocessing, shop, construction, and facility workers in operations that could cause a slug discharge must be trained in slug discharge prevention and spill reporting. This is accomplished through the Chemical Hygiene Plan and Worker Right-to-Know training and other training implemented by Department Safety Coordinators (DSCs). Drain disposal restrictions and spill discharge notification requirements are also posted through the use of sink stickers, which are required for laboratory, shop, and facility chemical use areas.

If prohibited chemicals or substances enter a sink or drain, immediately notify EH&S at 642-3073 during business hours or, after hours and weekends, call the University Police Department dispatch by dialing 642-6760 or 911 from a regular phone or 642-3333 from a cell phone. Upon receiving notification of a chemical release, EH&S will make the appropriate agency and Campus contacts.



Appendix I – Class A Class A chemicals are of little or no hazard in dilute aqueous solution. These are aqueous solutions suitable for disposal down the drain in quantities of up to approximately 100 g of solute per laboratory per day (e.g. 100 g of ethanol in one liter of water) Class A chemicals include many simple organic and inorganic compounds, as well as common inorganic chemicals. This includes most normal biological metabolites and nontoxic cellular constituents (proteins, nucleic acids, carbohydrates, soluble fats, and their precursors and catabolites).

Appendix IV – Additional Guidance on the Determination of Solubility There are many approaches that may be used to determine a chemical compound's solubility in water. The following discusses two of the more common approaches. The solubility class of the compound to be released could be determined directly from common literature data (e.g., Handbook of Chemistry and Physics - CRC Press, and Lange’s Handbook of Chemistry - McGraw-Hill Book Company). If a compound is classified as “vs’ (very soluble) or “s” (soluble), this would indicate the compound is “readily soluble.” On the other hand, if it is classified as “i” (insoluble), “sls” (slightly soluble), or “vsls” (very slightly soluble), this would indicate materials that are “not readily soluble.” Certain compounds are designated as class “d” (decompose). Additionally, if the decomposed species of these compounds are classified as either ‘vs’ or ‘s,’ this would indicate that the parent compound is “readily soluble.” If these decomposed species are simple ions, such compounds (class ‘d’) should be considered “readily soluble.” Compound solubilities (g/100 ml or mole fraction per 100 ml) are also listed in the chemical literature. From a review of general scientific literature, “formal solubilities” greater than 0.003 mole/liter would indicate the compound is readily soluble. Formal solubilities less than 0.003 mole/liter would indicate compounds that are “not readily soluble.” Solubility information is readily available from the supplier. Materials that are “NRS” or “Unknown” indicate these materials MAY NOT be disposed to the campus sanitary sewer system. ONLY materials that have a solubility of RS can be disposed to the sanitary sewer system. Solubility Product (Ksp) Determination: The solubility product constant of the compound could also be used to determine if a compound is readily soluble in water. The solubility product constant, Ksp, for a strong electrolyte MmAa, is expressed as:

Ksp = [M] m [A] a where “[M]” and "m" are the ionic concentration (mole/liter) and the number of moles, respectively, of the dissolved cation; and [A] and "a" are the ionic concentration and the number of moles, respectively, of the dissolved anion.

For a simple electrolytic compound, with one mole of a dissolved cation species and one mole of a dissolved anion species, a Ksp greater than 1.00 E-05 mole/liter would indicate that a compound is readily soluble. For other compounds with more complex dissolution reactions (i.e., more than one mole dissolved for each species and/or more anionic or cationic species present in the dissolved products), the Ksp constant would increase exponentially, based on the number of moles and/or the number of dissociated species. For example, if three moles are present (two for the anion and one for the cation), the unit of Ksp would be:

Mole3/liter3, and the corresponding Ksp would be (1 E-05)3/2 or 3.2 E-08 mole/liter; the same principle could be applied for more complex dissolution reactions.

Formal Solubility Determination: Compound solubility (g/100 ml or mole fraction per 100 ml) are also listed in the chemical literature. From a review of general scientific literature, "formal solubilities" greater than 0.003 mole/liter would indicate that a compound is readily soluble. The general relation between the formal solubility, Sf, and the solubility product, Ksp, of a strong electrolyte MmAa in water is given by: Sf = (Ksp/(mm aa ))1/(m+a)

where Ksp is the solubility product, [M] is the molar concentration of the metal ion (cation), [A] is the molar concentration of the anion, "m" is the number of moles of dissolved cation per mole of



dissolved substance, and "a" is the number of moles of the dissolved anion per mole of dissolved substance.

A formal solubility of less than 0.003 mole/liter indicates a compound that is not readily soluble. It should be pointed out that all values mentioned above (e.g., solubility class, formal solubility, and solubility product) correspond to measurements taken under standard conditions (e.g., 25øC, 101.3 kPa, pH of 7, and Eh of 0). If material to be released would not qualify as being readily soluble, it will require an exemption from the campus requirements. Exemptions are judged on a case-by-case basis. A permit for disposal of these materials may be granted, if it is demonstrated that release to sanitary sewerage is consistent with applicable regulations and in the public interest.

Appendix V – Decision Making Tree

Implementation of the UC Berkeley Drain Disposal Requirements for Chemicals Notice: EBMUD regularly monitors campus wastewater. Failure to comply with wastewater discharge regulations could lead to fines of up to $25,000 per day and/or restrictions on University water use.

Hazardous Wastes Hazardous wastes are prohibited from discharge. Chemical wastes are hazardous if they are: • corrosive • reactive • ignitable • moderately or highly toxic

General Rules for Sanitary Drain Disposal Only water-soluble substances may be disposed of in sinks, toilets, and floor drains. Solutions should be flushed down the drain with an appropriate amount of water. (Residue animal or vegetable fats and oils generated as a result of normal cleaning activities are an exception to the solubility rule. However, significant amounts of these oils and fats (more than a 500 ml, approximately) can cause clogging in interior drains and so should be collected and disposed of appropriately. Only solutions in the range of pH 5-10 may disposed of in the sink, unless at the Richmond Field Station where compounds must be in the pH range 6 – 10, Highly toxic, malodorous, or lachrymatory (that is, those that cause strong eye irritation) chemicals shall not be disposed of down the drain. Old, unwanted, or waste chemicals and products must not be poured down the drain as a means of disposal. These materials must be picked up EH&S personnel.

Specific Process for Laboratory Drain Disposal

Step One Do you know the chemical identity of the material and the concentration? Are you sure that the material is not hazardous (corrosive, reactive, ignitable, moderately or

highly toxic). Is the pH between 5 and 10? (Unless at the Richmond Field Station, where compounds must be

in the pH range 6 – 10.)

If the answer to any of the above is NO, the material cannot be disposed of to the sewer. If the answer to all of the above is YES, proceed.

Step Two Is the material a Class A? (chemicals that pose little or no hazard in dilute aqueous solution). Class A chemicals include many simple organic and inorganic compounds, as well as common inorganic chemicals. Included in Class A are most normal biological metabolites and non-toxic cellular constituents (proteins, nucleic acids, carbohydrates, soluble fats, and their precursors and



catabolites). A partial list of Class A chemicals, derived from state regulations and Appendix K of Reference 2, is provided in Appendix I. If YES, these aqueous solutions are suitable for disposal down the drain in quantities of up to approximately 100 g of solute per laboratory per day (e.g. 100 g of ethanol in one liter of water). If NO, continue.

Step Three Is the material a Class B? (chemicals of moderate hazard in dilute aqueous solution). Class B chemicals include all of the chemicals listed as toxic (T) in the California Code of Regulations Section 22-66261.30 et. seq. that are water soluble, except for those listed as Class A chemicals in Appendix I or Class C chemicals in Appendix III. Class B chemicals also include all inorganic salts listed in reference 2 as high hazard in tables 6.1 and 6.2. A partial list of Class B chemicals appears in Appendix II. If YES, these aqueous solutions are suitable for disposal down the drain with excess water in quantities no greater than 1 g of solute per laboratory per day). If NO, continue.

Step Four Is the material a Class C? (chemicals that may not be drain disposed in any amount except by written approval of the LOSC or their delegate). Class C chemicals include all chemicals that are not soluble as defined above, chemicals that cause unacceptable concentrations of offensive, toxic, or explosive vapors, and chemicals that are toxic or reactive at concentrations below 1 ppm in aqueous solution. Class C chemicals include the chemicals identified in the Main Campus EBMUD Wastewater Discharge Permit "Priority Pollutant Management Plan" Compliance Requirement (Federal Clean Water Act priority pollutants listed in 40 CFR Part 122 Appendix D, Tables II and III). A partial list of Class C chemicals appears in Appendix III. If YES, these aqueous solutions are not suitable for disposal down the drain. However, you may ask for a specific exception by making a request to the LOSC. Contact EH&S to determine how this request is made. If NO, contact EH&S for assistance in classifying your material for disposal purposes or to arrange pick-up of this material for proper disposal.

Note: Radioactive material may NOT be disposed of down the sewer.
