Significance and Use5.1 This is intended to outline O and6.3.2.2 Where assistance by the optical fiber cable ownermay be necessary.6.4 Routine Operating Procedures:6.4.1 Notification:6.4.1.1 The sewer operator an
12、d fiber cable system ownershould notify the other entity as far in advance as possible forplanned, routine operations.6.4.1.2 Improper cable repair or maintenance proceduresmay damage the sewer or optical fiber system, creating anunsafe situation. Because of this risk, the fiber cable systemowner mu
13、st notify the sewer pipeline operator as to the natureof the intended repair or maintenance and verify whether seweroperator supervision or oversight is required during the repairor maintenance.6.4.2 Extended Duration Access (4 hours+) to Sewer Vaultsby Optical Fiber System OwnerWhen accessing a sew
14、ervault or sewer manhole, the optical fiber cable owner mustprovide the sewer pipeline operator with at least 48 hours priornotice. If re-cabling, replacing the conduit or other extendeddurations repairs are contemplated, the optical fiber systemowner must provide with that notice, written repair pr
15、ocedures,the duration and hours that the vault or manhole is beingaccessed and other requirements which may be locally required(traffic control plans, odor control, and so forth).6.4.3 Sewer Service ConnectionsThe optical fiber cableowner must provide the sewer pipeline operator with preferredmethod

In the absenceof those preferences, the sewer pipeline operator may use anycustomary method.6.4.4 Sewer Pipeline Maintenance and RehabilitationTheoptical fiber cable owner must provide the sewer pipelineoperator with preferred methods for chemicals used for od

20、-ously identified as containing optical fiber cables. A contactnumber must be provided where the optical fiber cable owneror sewer pipeline operator may access further instructions onhow to safely proceed.6.6.2 ConduitConduit containing optical fiber cable (lo-cated outside of the pipeline) must be
