Quality System Procedure
08.4 Final Inspection for Marketers
rev-08a00 / issued 11-07-08 - Approved by: Andy Erikson
1.0 Purpose and Scope
The purpose of this procedure is to provide instructions, and to assign responsibility for performing
and recording verification of final product and storage tanks. This procedure applies to all finished
biodiesel and biodiesel blend products prior to shipping (and in some cases during shipping). This
procedure applies to BQ-9000 Certified Marketers.
1.1 Definitions
1.1.1 ASTM: ASTM International, originally known as the American Society for Testing and Materials
(ASTM), was formed over a century ago. ASTM International is one of the largest voluntary standards
development organizations in the world. ASTM develops technical standards for materials, products,
systems, and services.
1.1.2 Biodiesel: a fuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils
or animal fats and meets ASTM D 6751, designated B100.
1.1.3 Blend: a blend of Biodiesel with fuel oils in a specified ratio, designated Bxx, where xx is the volume
percent biodiesel.
1.1.4 External Lab: A third party laboratory that the biodiesel organization can use to test product
samples.
1.1.5 Internal Laboratory: A laboratory that is operated or managed by the biodiesel organization.
1.1.6 Marketer: an entity engaged in the business of the distribution and sale of biodiesel and/or biodiesel
blends of B2 or greater.
1.1.7 Producer: the entity responsible to the first purchaser of neat biodiesel for that neat biodiesel to
meet the specification of ASTM D6751. A producer can also be engaged in the distribution of biodiesel
blends of B99 or higher.
1.1.8 Verification: confirmation by examination and provision of objective evidence that specified
requirements have been fulfilled.

1.2 Discussion
Formal ASTM biodiesel blends specification now include B1-B5, B6-B20, with variations for
burner and fuel use. Associated regulatory controls exist. Compliance is critical.
a)
b)
c)
d)
Retail Pump Labeling define fuel grades associated with regulatory controls (B1-B5,B6-B20,Bxx)
ASTM D975 - diesel fuel may contain up to 5% biodiesel (B1-B5)
ASTM D396 - fuel oils (burner, bioheat) may contain up to 5% biodiesel (B1-B5)
ASTM D7267 – biodiesel blend specification for B6-B20
All finished products are subjected to final inspection before they are shipped. The Quality
Assurance department is responsible for final inspections and for the release of product for
shipping. This includes controls of final product lots within distribution tanks, and the verification
of product at time of shipping.
Storage tanks with inactivity are verified for continued quality of tank and product.
The primary focus is on defect prevention, rather than detection. Normally, by the time products
are completed they have been completely verified through the program of receiving and inprocess inspections. The purpose of final inspection is not to re-inspect the products, but to
ascertain that all verification activities have indeed been carried out with satisfactory results.
However, should there be suspect product nonconformance, the product is isolated and will not
be shipped until corrective actions have been successfully completed.
2.0 Procedure
2.1 Method of Sampling
ASTM D 4057, provides standard sampling methods.
2.2 Required Sample Volumes and Containers
Reference WI 20-10-0001(Providing Samples to QA) for appropriate containers, identification,
and volumes of fuels required for testing.
2.3 Nonconforming Product
Procedures for Non-conforming product (QSP_09.1), define the actions required if product lot
fails to pass required inspections or test.
2.4 Inspection Records
QA Inspection Sheets log the inspection results, which includes product tested, appropriate
traceability-ids, properties to test, property specification(acceptance limits), actual results,
approval sign-off / date, test method specification, and test method revision.

2.5 B100 Storage
2.5.1 B100 Storage & Distribution Tanks
All B100 storage and distribution tanks should be dedicated to biodiesel service. If a tank is
changed from some other service to biodiesel storage, the tank should be drained dry, cleaned,
and then inspected. Inspection shall be documented.
2.5.2 B100 Storage Tank Sampling & Testing
Quality assurance shall verify sustain quality of stored B100. Given the verification of B100
specification on receipt, verification is focused on the sustained quality of stored and aging fuel.
B100 shall conform to ASTM D6751 specification.
If out-of-specification, appropriate procedures are invoked:
a) nonconforming product (QSP_09.1)
b) corrective actions (QSP_10.1)
2.5.3 B100 Storage Tank Homogeneity
Upper, middle and lower samples shall be taken every 30 days based on ASTM D 4057 sampling
guidelines. All three samples shall conform to tank homogeneity requirements ASTM D 1298 or
ASTM D 4052. If requirements are met, then a composite sample is created by combining the
three upper, middle and lower samples for testing purposes in section 2.4.4 B100 Tank Testing. If
relate density of samples fall outside the homogeneity requirements, then each sample must be
tested individually.

2.6 Fuel Blending and Distribution
2.6.1 Fuel Blending
Fuels shall be blended and inspected per applicable blend specification and sales requirement.
See referenced specification by B1-B5(road & bioheat), B6-B20.
Fuel blending is a controlled process, which shall be performed and documented to ensure
biodiesel blends are of correct product proportions and have been adequate mixed. This includes
the measuring and recording the volumes and blend levels as verified through bills of lading,
meter printouts, %blend inspection devices, or other auditable records of both the biodiesel and
fuel oils which comprises the blend. These records shall be retained for a minimum of two years.
2.6.2 Blended Tank & Truck Homogeneity
The process for blending biodiesel and fuel oils is validated for tank homogeneity after 5
consecutive blended lots meeting Tank Homogeneity requirements. To validate, the upper,
middle and lower samples shall be taken based on ASTM D 4057 sampling guidelines. All three
samples shall conform to tank homogeneity requirements:
Property
Relative Density
Test Method
ASTM D1298 or ASTM D4052
Limits_________
range 0.006
If operational parameters fall outside of the Tank Homogeneity requirements, the blend
procedure shall be re-evaluated and revised as appropriate. Actions are documented per
Corrective Action (QSP_10.1).
2.6.3 Tanks Containing Blended Biodiesel
All blend tanks should be dedicated to biodiesel blend service. If a tank is changed from some
other service to biodiesel blend storage or distribution, the tank should be drained and cleaned
prior to use. Inspections shall be documented per Corrective and Preventive Action (QSP_10.1).
Each time blending of biodiesel occurs, a composite sample of the blended fuel tank shall be
obtained and retained for a minimum of 60 days.
2.6.4 Blended Fuel Tank Testing
Blend tanks with no activity over a 30 day period shall be validated prior to use. An outlet sample
shall be tested for moisture and sediment per ASTM D 4176 (procedure 2).
If out-of-specification, appropriate procedures are invoked:
a) nonconforming product (QSP_09.1)
b) corrective actions (QSP_10.1)
