# §141.713. Schedule for compliance with Cryptosporidium treatment requirements.

- (a) Following initial bin classification under [§ 141.710(c)](/cfr/40/141.710.md?p=c), filtered systems must provide the level of treatment for Cryptosporidium required under [§ 141.711](/cfr/40/141.711.md) according to the schedule in [paragraph (c)](#c) of this section.
- (b) Following initial determination of the mean Cryptosporidium level under [§ 141.712(a)(1)](/cfr/40/141.712.md?p=a-1), unfiltered systems must provide the level of treatment for Cryptosporidium required under [§ 141.712](/cfr/40/141.712.md) according to the schedule in [paragraph (c)](#c) of this section.
- (c) **Cryptosporidium treatment compliance dates.**
- (d) If the bin classification for a filtered system changes following the second round of source water monitoring, as determined under [§ 141.710(d)](/cfr/40/141.710.md?p=d), the system must provide the level of treatment for Cryptosporidium required under [§ 141.711](/cfr/40/141.711.md) on a schedule the State approves.
- (e) If the mean Cryptosporidium level for an unfiltered system changes following the second round of monitoring, as determined under [§ 141.712(a)(2)](/cfr/40/141.712.md?p=a-2), and if the system must provide a different level of Cryptosporidium treatment under [§ 141.712](/cfr/40/141.712.md) due to this change, the system must meet this treatment requirement on a schedule the State approves.
