N.J. Admin. Code § 7:18-7.7 - Laboratory quality control and recordkeeping
(a) A laboratory
performing acute toxicity testing shall develop and implement a quality control
program. The laboratory shall not perform acute toxicity testing without having
such a program. The laboratory shall have a written description of its program
on file and be able to produce a copy during an on-site inspection. The written
description shall include all methods manuals used for culturing test
organisms, and all testing protocols used by the laboratory. The quality
control program description, or standard operating procedures (SOP) manual,
shall be specific to the operations of the laboratory and not a generalized
document.
(b) The laboratory shall
make records of all analytical control tests and quality control checks on
equipment and materials. The laboratory shall maintain the records for at least
five years. The laboratory shall file and maintain data and other records in an
accessible location on the laboratory's premises for one year after the date of
analysis so that reviews can be conducted during on-site audits.
(c) If the laboratory discovers an error in
the analysis of a regulatory sample, and the error may affect the validity of
the reported analytical result, the environmental laboratory manager shall
report the error to the regulatory program for which the analysis was
conducted, and to the client. The laboratory shall make this notification
within 72 hours after discovery of the error.
(d) Laboratories performing acute toxicity
testing shall comply with the following requirements when performing quality
control checks of laboratory media, equipment, and supplies:
1. Operate each pH meter in accordance with
7:18-3.3(a)3.
Rinse the probe with laboratory pure water immediately after each use period.
Label commercial buffer solutions with the date of receipt and the date of
initial use;
2. Operate top loader
or pan balances in accordance with
7:18-3.3(a)2;
3. Verify all temperature measuring devices
using the procedures listed in
7:18-3.3(a)5;
4. The temperature of air or water-jacketed
incubators, aluminum block incubators, water baths, and incubator rooms shall
be recorded either continuously or daily from in-place thermometers immersed in
liquid and placed on at least one of the shelves in use. Keep the records in a
log book, signed and dated by the analyst;
5. Record date, time, pressure and
temperature of an autoclave either continuously, or individually during each
sterilization cycle. Keep the records in a log book, signed and dated by the
analyst;
6. The time and
temperature of hot air ovens shall be measured with a thermometer either
continuously or individually during each cycle, with the bulb of the
thermometer placed in sand. Record the date, time and temperature of each
cycle. Keep the records in a log book, signed and dated by the
analyst;
7. Monitor the temperature
of each refrigerator in accordance with the procedures listed in
7:18-3.3(a)7;
8. Label all reagents and solutions to
indicate identity and, when applicable, titer, strength or concentration,
manufacturer's recommended storage requirements, preparation and expiration
date, and other information pertinent to identification. Do not use materials
of substandard reactivity or deteriorated materials. Discard all outdated
material immediately;
9. At least
annually, check conductivity and salinity meters equipped with conductivity
cells having platinum electrodes. Perform the check over the range of interest
using at least five concentrations of a standard potassium chloride solution.
Check conductivity cells not having platinum electrodes against a conductivity
meter equipped with platinum electrodes. Perform this check annually and record
the raw data, cell constant, and results in a log book, signed and dated by the
analyst; and
10. Check dissolved
oxygen meters weekly, using the Winkler method. Record the results in a log
book signed and dated by the analyst.
(e) Only the laboratory manager, supervisor
or quality assurance officer is authorized to make changes in laboratory
procedures. Changes are effective only if:
1.
The change is made by the manager, supervisor or quality assurance officer of
the laboratory;
2. The manager,
supervisor or quality assurance officer makes the change in writing, signed and
dated by the manager, supervisor or quality assurance officer, and includes the
change in the laboratory's SOP manual.
(f) A laboratory shall not perform acute
toxicity tests unless it keeps current laboratory SOP and reference manuals in
the immediate bench area of laboratory personnel engaged in examining samples
and performing toxicity testing and other related procedures. The laboratory
may use textbooks to supplement the manuals, but shall not replace the manuals
with the textbooks. The manuals shall include information relating to:
1. The analytical methods to be used,
properly designated and dated to reflect the most recent supervisory reviews;
and
2. Any applicable
regulations.
(g) A
laboratory conducting a flow-through toxicity test shall check the temperature
in the exposure chambers, the flow rate through the exposure chambers, and the
maintenance of effluent concentrations. The laboratory shall conduct these
checks when the test is initiated, at least once every 24 hours for the
duration of the test, and upon completion of the test. The laboratory shall
document these measurements, and any resulting adjustments to the flow-through
dilutor system, in the toxicity test report.
(h) A laboratory performing an acute toxicity
test shall establish an acute toxicity test precision requirement that the 95
percent confidence interval be within +/-30 percent of the estimated or
incipient EC[50] or LC[50] value.
(i) A laboratory performing acute toxicity
tests shall keep records and report data in accordance with the requirements of
(i)1 and 2 below. The records to be retained include raw data records, quality
control data records, chain-of-custody forms, laboratory reports, and the
information required under (i)2 below.
1. The
laboratory shall retain each record for at least five years after the date of
the analysis. The laboratory shall file and maintain data and other records in
an accessible location on the laboratory's premises for one year after the date
of analysis so that reviews can be conducted during on-site audits.
2. The laboratory shall record the following
information as part of the daily log of feeding, behavioral observations, and
mortality of organisms during holding and acclimation:
i. The water temperature of holding
tanks;
ii. The air temperature in
the culturing/holding room;
iii.
Mortalities or organisms per holding tank;
iv. The analysis of laboratory grade waters
as specified in
7:18-7.4(b);
v. The food and feeding schedule;
and
vi. General observations of
behavior and condition.
(j) The laboratory shall not accept custody
of regulatory samples unless a chain-of-custody form is submitted with the
samples, in accordance with
7:18-9.5(c).
1. Before accepting custody of a regulatory
sample, the laboratory shall determine that the sample is properly labeled and
has been collected, preserved, processed, stored and transported in accordance
with the provisions of this subchapter. If the sample fails to meet those
requirements, the laboratory shall indicate that failure on the
chain-of-custody section of the sample request form or the chain-of-custody
form;
2. The laboratory's sample
custodian accepting responsibility for the sample shall sign the
chain-of-custody form;
3. The
laboratory shall have an internal chain-of-custody procedure or an alternate
sample tracking procedure which establishes the integrity and completely tracks
the custody of a sample during its lifetime in the laboratory; and
4. If the analysis was not performed at the
environmental laboratory that first received the sample, the chain-of-custody
form shall include the name, address and identification number of the New
Jersey certified environmental laboratory to which the sample was
forwarded.
(k) If a
laboratory violates any of the requirements of this subchapter in the process
of performing an acute toxicity test, the laboratory shall prefix the test
result, that is, LC[50] or EC[50] value, with the letter "J," and describe the
violation in the "remarks" section of the test report.
