||New Low Level Air Analysis Method Required by
NJDEP’s Site Remediation and Waste Management
The NJDEP Site Remediation Waste Management (SRWM) Program
has developed criteria for a Low Level Volatile Organics Method
for air sampling and analysis that will be used in place of
USEPA Method TO-15. The new method is designated as NJDEP-SRWM
Low Level USEPA Method TO-15, March 2007 (NJDEP-LLTO-15-3/2007).
The specific details of the new method requirements are given
in the following three documents:
- NJDEP Modified Low Level TO-15 Method (NJDEP-LLTO-15-3/2007) [pdf 406 Kb]
- NJDEP Ambient Air Regulatory Data Report Format (Appendix
1) [pdf 530 Kb]
- Method NJDEP-LLTO-15-3/2007 Data
Reporting Spreadsheet [pdf 24
These documents can be obtained directly from the NJDEP’s
Office of Quality Assurance (OQA) website at:
or on the NJDEP Site Remediation & Waste Management (SRWM)
Program’s Vapor Intrusion website at:
Included in the method is the specific list of compounds
that meets the requirements of the SRWM Program. This list
is contained in Table 2 of the method. To submit data to the
Department, laboratories must be certified for all compounds
in Table 2 of Method NJDEP-LLTO-15–3/2007. Laboratories
cannot add additional compounds to this method.
Among other requirements, Method NJDEP-LLTO-15–3/2007
will formally lower the reporting limit for volatile organics
in indoor air to 0.2 ppbv for a majority of the compounds.
However, a select group of compounds listed in the method
will have higher reporting limits. These compounds and their
associated reporting limits can be found in Table 2 of the
The Department expects that as of July 1, 2007 USEPA Method
TO-15 will no longer be accepted for any indoor air or soil
gas analysis by the SRWM Program. Please review the above
named websites on a regular basis for notifications and updates
on certification and vapor intrusion status and issues.
Laboratory Certification Process
Effective immediately, the Department’s Office of Quality
Assurance will begin offering certification for Method NJDEP-LLTO-15–3/2007
under the New Jersey Environmental Laboratory Certification
Program (NJ-ELCP) and the National Environmental Laboratory
Accreditation Program (NJ-NELAP). The requirements for applying
for certification are as follows:
For Laboratories New to the Certification Program
or For Certified Laboratories Not Having USEPA Method TO-15
The laboratory shall submit the following to the OQA.
- An application and appropriate fees for new parameter
codes CAP03.06850 – CAP03.06972.
- A standard operating procedure (SOP). The SOP shall contain
all operational details including calibration and QC procedures
with associated acceptance/rejection criteria. Hard copy
submittal is required.
- Submittal of all method performance data to include:
- Limit of Detection (LOD) Study.
- Laboratory’s procedure for determining LOQ
(can be referenced in SOP).
- Precision and Accuracy (P&A) Study.
- Initial Calibration Summary Reports and Associated
- Method Blank Summary Report and Associated Chromatogram.
- Analytical data report of a real environmental sample.
The sample must be collected in a 6 Liter canister for a
24 hour period from an indoor air location. Submittal of
data from a Proficiency Test Sample or a sample generated
and/or collected on the laboratory property is not acceptable.
(Original and one copy are required).
- Submittal of all the electronic deliverables as specified
in Appendix 1 of the Ambient Air NJDEP Regulatory Data Report
Format. (1 set of electronic data deliverables is required).
An onsite laboratory assessment is a requirement for certification.
An acceptable onsite laboratory assessment must be concluded
prior to granting certification for the new method.
For Laboratories Currently Certified for USEPA
All of the submittals listed in Items 1 through 5 above are
required. An onsite laboratory assessment may not be required
if the laboratory’s data and documentation are acceptable
and if the laboratory has had an acceptable onsite assessment
by the NJDEP’s OQA within the last two years.
Overall, certification will be granted after a laboratory
has successfully completed the following OQA assessment criteria:
Application for Certification and Submittal of Fees
Standard Operating Procedures Review
Method Performance Data Review
Method Data Report Review
Method Electronic Data Review
Onsite Laboratory Assessment (if required)
Any method performance and/or data reporting deficiencies
determined during data review and during the on-site assessment
will be brought to the attention of the laboratory in writing.
The laboratory will have the opportunity to provide corrective
actions based on the findings. Certification will only be
granted after any and all corrective actions from method review
and onsite assessments have been acceptably completed.
Analytical Data Package Compliance
Please note that if after certification has been granted
and if the laboratory is found to be routinely unable to properly
submit a compliant data package, the laboratory may be fined,
subject to a loss of certification and/or found "ineligible
to report data to the NJDEP". Data package requirements
are found in Appendix 1 of Method NJDEP-LLTO-15–3/2007.

Quality Assurance at (609) 292-3950.
