Objective

• Use US EPA Office of Solid Waste (OSW) and DTSC
  guidance documents to analyze advanced issues.
• Examine scenarios and discuss varying
  interpretations.
• Three topic areas
• Part I Point of generation
• Part II Waste Analysis
• Part III Is it a Container or is it a Tank?
• Well start with the laws and regulations then
  progress through guidance documents and scenarios.

5
Part I,Point of Generation

• Is it Waste?
• Is it a Hazardous Waste?

6
Is it a Waste?66261.2. Definition of Waste

• 66261.2(a) "Waste" means any discarded material
  of any form (liquid, semi-solid, solid or
  gaseous) that is not excluded by 66261.4(a) or
  66261.4(e) or that is not excluded by HSC
  25143.2(b) or HSC 25143.2(d).
• (b) A discarded material is
• (1) relinquished, or
• (2) recycled, or
• (3) considered inherently waste-like.
• Of course there are other exceptions

7
Is it a Hazardous Waste?66261.3. Definition of
Hazardous Waste

• 66261.3 (a) A waste as defined in 66261.2 is a
  hazardous waste if
• (1) it is not excluded from classification as a
  waste or a hazardous waste under HSC 25143.2(b)
  or 25143.2(d) or 66261.4 and
• (2) it meets any of the following criteria
• (A) it exhibits any of the characteristics of
  hazardous waste identified in article 3
• (B) it is listed in article 4

8
A Hazardous Waste is

• Declared Generator decides to manage as a
  hazardous waste
• Characteristic A representative sample exhibits
  a hazardous characteristic (RCRA D001 to D043
  California corrosive, reactive, toxic) (22
  CCR, Ch. 11, Art. 3)
• Listed (22 CCR, Ch. 11, Art. 4)
• F listed (Non-Specific Sources)
• K listed (Specific Sources)
• P Listed (Acutely Hazardous Off-Spec, Spills)
• U listed (Hazardous Off-spec, Spills)
• M listed (Ch. 11, Art. 4,1 mercury containing
  products)
• Mixtures of solid hazardous waste
• Residues derived from a hazardous waste

9
Example of waste listed as hazardous due to
Benzene

• D018 Benzene concentration ? 0.5 mg/l TCLP
• F037 Petroleum refinery primary separation
  sludge
• F038 Petroleum refinery secondary separation
  sludge
• K085 Distillation bottoms from the production
  of chlorobenzenes
• P028 Benzene, (chloromethyl)- (commercial
  chemical product)
• U019 Benzene (commercial chemical product)

10
Mixture Rule

• A mixture of a solid waste a characteristic
  (Art. 3 or Subpart C) hazardous waste is
  hazardous only if the resulting mixture exhibits
  a hazardous characteristic.
• A mixture of a solid waste a listed (Art. 4 or
  Subpart D) hazardous waste that is listed only
  for ignitability, corrosivity or reactivity
  (I,C,R) is hazardous only if the resulting
  mixture exhibits a hazardous characteristic.
• A mixture of a solid waste a listed (Art. 4 or
  Subpart D) hazardous waste that is listed only
  for toxicity remain listed as a hazardous waste.

11
Derived from Rule(Treatment Residue)

• Residues from treating, storing or disposing a
  characteristic waste are hazardous only if they
  exhibit a characteristic of hazardous waste.
• Residues from treating, storing or disposing a
  listed waste, that is listed solely for
  ignitability, corrosive or reactive (I,C,R), are
  hazardous only if they exhibit a characteristic
  of hazardous waste.
• Residues from treating, storing or disposing a
  listed waste, which is listed for toxicity,
  remain a listed hazardous waste.

12
Who Makes a Waste Determination?

• The
• Generator

13
Whats A Generator? 66260.10

• Generator "any person, by site, whose act or
  process produces hazardous waste identified or
  listed in Chapter 11 or whose act first causes a
  hazardous waste to become subject to regulation.

14
Whats A Person? 66260.10

• Person "an individual, trust, firm, joint stock
  company, federal agency, corporation (including a
  government corporation), partnership,
  association, state, municipality, commission,
  political subdivision of a state, or any
  interstate body. Person" also includes any
  city, county, district, commission, the State or
  any department, agency or political subdivision
  thereof, any interstate body, and the Federal
  Government or any department or agency thereof to
  the extent permitted by law."

15
Whats A Site? 66260.10

• The term, "by site," refers to where a hazardous
  waste is generated. The regulations do not
  explicitly define the term site. But the
  regulations do define onsite.
• "Onsite" means the same or geographically
  contiguous property which may be divided by
  public or private right-of-way, provided the
  entrance and exit between the properties is at a
  crossroads intersection, and access is by
  crossing as opposed to going along, the
  right-of-way. Noncontiguous properties owned by
  the same person but connected by a right-of-way
  which that person controls and to which the
  public does not have access, is also considered
  onsite property.

16
Whose Act or Process?

• A generator is defined as the person whose act or
  process first causes a hazardous waste to become
  subject to regulation.
• Sometimes the generator of a waste may not
  necessarily be the person who actually produced
  the waste. For example, if a cleaning service
  removes residues from a product storage tank
  excluded under 261.4(c), the person removing the
  residues is the first person to cause the waste
  to become subject to regulation, not the owner of
  the tank.
• In case the cleaning service and the owner are
  co-generators.

17
Co-Generators

• The person removing the waste from the unit is
  not the owner or operator of the unit, but may be
  considered a generator. The owner or operator of
  the unit may also be considered a generator since
  the act of operating the unit led to the
  generation of the hazardous waste. In other
  words, both the remover of the waste and the
  owner or operator of the tank are considered to
  be co-generators.
• In cases where one or more persons meet the
  definition of generator, all persons are jointly
  and severally liable for compliance with the
  generator regulations. The parties may through a
  mutual decision have one party assume the duties
  of generator, but in the event that a violation
  occurs, all persons meeting the definition of
  generator could be held liable for the improper
  management of the waste (45 FR 72026 October 30,
  1980).

18
Point of Generation

• The point where a material becomes a waste is
  also the point where
• Waste determination is made samples are taken.
• Treatment tier determination is made
• Container tank standards are required
• RCRA Land Disposal Restrictions apply

19
Point of Waste OriginationDefined per 22 CCR
66260.10

• "Point of waste origination" (22 CCR) means as
  follows
• (1) When the facility owner or operator is
  the generator of the hazardous waste, the point
  of waste origination means the point where a
  solid waste produced by a system, process, or
  waste management unit is determined to be a
  hazardous waste as defined in this division.

20
Point of Waste Origination Defined 22 CCR
(Continued)

• NOTE In this case, this term is being used in
  a manner similar to the use of the term "point of
  generation" in air standards established for
  waste management operations under authority of
  the Clean Air Act in 40 CFR parts 60 , 61 and
  63.

21
Point of Waste Generation Defined per 40 CFR part
61

• Point of waste generation means the location
  where the waste stream exits the process unit
  component or storage tank prior to handling or
  treatment in an operation that is not an integral
  part of the production process, or in the case of
  waste management units that generate new wastes
  after treatment, the location where the waste
  stream exits the waste management unit component.
  (40 CFR Part 61)

22
Points of Generation

• Waste exits a non-waste unit or piece of
  equipment (e.g. radiator, parts washer).
• Waste exits a manufacturing process unit.
• Material is spent and a decision to discard or
  recycle is made.
• Decision is made to discard a P or U listed
  chemical.
• Treatment residue exits a treatment unit.
• Residue exits a recycling unit.

23
8.2 What Is the Point of Generation?

• According to RCRA and Sate law, when a waste is
  generated, you must identify whether the waste is
  hazardous
• hazardous waste identification must be made at
  the point where the waste is first generated.
  The point of generation is usually defined as the
  point at which a generator first determines that
  a material is no longer useful (or the point at
  which the generator decides to discard the
  material).
• www.epa.gov/OSWRCRA/hazwaste/ ldr/ldr-sum.pdf 

24
8.2 What Is the Point of Generation?

• However, under 40 CFR 261.4(c), hazardous waste
  is not generated from product or raw material
  tanksand pipelines, manufacturing process units,
  or associated non-waste-treatment-manufacturing
  units until it exits the unit or the HW remains
  in unit gt 90 days after the unit ceases to be
  operated for manufacturing, or for storage or
  transportation of product or raw materials.

OSW Answer (faxback 13395)

• Q. A D002 acidic waste and a D002 basic waste
  from two different manufacturing process are
  individually piped to a collecting pipe. The two
  wastes neutralize each other in the collecting
  pipe and the result is a non-hazardous waste. Is
  there a point of generation?
• A. Each of the corrosive wastes has a point of
  generation upstream of the collecting pipe.

NO 66268.3. Dilution Prohibited As a
Substitute for Treatment

• (a) No generator, transporter, handler, or
  owner or operator of a treatment, storage, or
  disposal facility shall in any way dilute a
  restricted waste or the residual from treatment
  of a restricted waste as a substitute for
  adequate treatment to achieve compliance with
  article 4 or article 11 of this chapter, to
  circumvent the effective date of a prohibition in
  article 3 or article 10 of this chapter, to
  otherwise avoid a prohibition in article 3 or
  article 10 of this chapter, or to circumvent a
  land disposal prohibition imposed by RCRA section
  3004 (42 U.S.C. 6924).

50
YES DilutionRef EPA 530-R-01-007 (revised
August 2001)

• Wastes that are aggregated or mixed as a part of
  a legitimate treatment process, and are
  subsequently diluted as a result, are not
  considered to be impermissibly diluted under LDR.

Is a treatment authorization required?
Yes, authorization is required. Waste A C are
hazardous waste. Dilution is treatment.
Additional treatment might be required to meet
LDR standards.
52
Treatment is

• 25123.5(a) Treatment" means any method,
  technique, or process which is not otherwise
  excluded from the definition of treatment by this
  chapter and which is designed to change the
  physical, chemical, or biological character or
  composition of any hazardous waste or any
  material contained therein, or which removes or
  reduces its harmful properties or characteristics
  for any purpose.

53
Land Disposal Restrictions(LDRs)

• LDRs were established to keep landfills from
  becoming superfund sites.
• The dilution prohibition is in chapter 18 (LDRs).
  
• But deactivation (DEACT) is a form of treatment
  permitted under LDRs that can be achieved by
  dilution.
• The dilution reduce the toxics concentration
  below hazardous thresholds, then water could
  evaporate in non-hazardous waste surface
  impoundments and the resultant sludge could be
  hazardous and leach, so stringent treatment
  standards were mandated by the courts.

54
LDR Treatment Standards Example D006 Sludge
w/Cadmium

• HAZARDOUS WASTE THRESHOLD
• D006 Cadmium concentration ? 1.0 mg/l TCLP or
  STLC
• Ni concentration ? 20 mg/l STLC
• LDR TREATMENT STANDARDS

Commingling RefEPA 530-R-01-007 (revised August
2001)

• Where a waste stream will eventually be
  commingled with other waste streams, the Agency
  generally requires waste identification and LDR
  determination to be made at the point the waste
  is generated, prior to the commingling, even if
  the commingling occurs within a pipe (except in a
  totally enclosed treatment system). One exception
  to this rule is that the point of generation for
  tank cleanouts occurs at the end of the rinseouts
  in the receiving rinsate tank, even though the
  first rinse is likely to be of higher
  concentration than the other rinses.

66
Is this Dilution Permitted?

• Aggregation for Centralized Treatment is
  generally acceptable dilution provided that the
  type of treatment will remove or destroy the
  contaminants.
• You cant aggregate to dilute, but you can
  aggregate for efficient treatment.
• Wastes that are aggregated or mixed as a part of
  a legitimate treatment process, and are
  subsequently diluted as a result, are not
  considered to be impermissibly diluted under LDR.

67
Is it Treatment?

• HSC 25123.4 (b) (1)Treatment does not include
• (C) Combining two or more waste streams that are
  not incompatible into a single tank or container
  if both of the following conditions apply
• (i) The waste streams are being combined solely
  for the purpose of consolidated accumulation or
  storage or consolidated offsite shipment, and
  they are not being combined to meet a fuel
  specification or to otherwise be chemically or
  physically prepared to be treated, burned for
  energy value, or incinerated.
• (ii) The combined waste stream is managed in
  compliance with the most stringent of the
  regulatory requirements applicable to each
  individual waste stream.

68
Do LDRs Apply?

• These wastes are subject to land disposal
  restrictions. Removing the characteristic of
  corrosivity by combining these wastes can satisfy
  the treatment requirement of deactivation set out
  in 40 CFR 268.42, (now 268.40) Table 2. Dilution
  may not be appropriate if there are other
  requirements for the waste matrices. (FAXBACK
  13395)
• Combining waste acid a waste caustic to remove
  the characteristic of corrosivity is regulated
  treatment in California.

Recycling LDRs

• A generator that recycles onsite is still subject
  to LDRs. (FAXBACK 13280)

• A hazardous waste which is generated in a product
  or raw material storage tank is not subject to
  regulation under this division until it exits the
  unit in which it was generated unless the
  hazardous waste remains in the unit more than 90
  days after the unit ceases to be operated.
• The exemption in this subsection applies only to
  the hazardous waste generated in the above-named
  tanks, not to the tanks themselves. The tanks
