# §1066.910. SHED enclosure specifications.


Enclosures for evaporative and refueling emissions must meet the specifications described in 40 CFR [86.106-96](/cfr/40/86.106-96.md), [86.107-96(a)](/cfr/40/86.107-96.md?p=a), and [86.107-98(a)](/cfr/40/86.107-98.md?p=a).


# §1066.915. Enclosures; auxiliary systems and equipment.


Enclosures for evaporative and refueling emissions must be equipped with fans, blowers, and measurement and data recording equipment as described in 40 CFR [86.107-98(b) through (h)](/cfr/40/86.107-98.md?p=b..h) and [(j)](/cfr/40/86.107-98.md?p=j).


# §1066.920. Enclosure calibrations.


Enclosures for evaporative and refueling emissions must meet the calibration specifications described in 40 CFR [86.116-94](/cfr/40/86.116-94.md) and [86.117-96](/cfr/40/86.117-96.md).


# §1066.925. Enclosure calculations for evaporative and refueling emissions.


Calculate emissions for evaporative emissions as described in [40 CFR 86.143-96](/cfr/40/86.143-96.md). Calculate emissions for refueling emissions as described in 40 CFR [86.143-96](/cfr/40/86.143-96.md) and [86.156-98](/cfr/40/86.156-98.md).


# §1066.930. Equipment for point-source measurement of running losses.
